while
and you who have had a lot of fans but I
think so
expect to see quite so many journalists
here today something must be going on
thank you so much for joining us I'm
Brian McClendon
I'm in charge the Google GEO Group here
and I we are in charge of Google Maps
earth and all the services that are
possible with your day to day
I'm gonna be talking about three
underlying principles and Google Maps
Rebecca Moore is going in to do some
uses Google Maps they're incredibly
inspiring
we're gonna demo some cool new featuresand then finish up the talk
but first I wanna give you some history
about where we came from where I came
from
I spent most my career in Silicon Valley
ninety-five percent that time was within
a mile the Googleplex
I were to become a concert in graphic
traded those years building
graphic supercomputers these are very
expensive machines they were used to
make the movies like terminator 2: in
jurassic park
in the abyss they're also used in
scientific visualization
in flight simulators this picture the
picture here
is actually be infinite reality this was
the most advanced machine at the time
1986
and had this powerful feature to zoom a
texter from
outer space all the way down to near
future but we wanted to demo the really
demonstrated that
who came up with this thing we call
space to face and it may look familiar
to you
because it was a satellite image the
whole globe very low resolution
with satellite image the Matterhorn
followed by a real injury the Matterhorn
combined with terrain data and this demo
was so beautiful and you know was really
the best thing you could show for into
reality it inspired a group with the
engineers who worked on two years later
we decided to try to reproduce this
functionality
on E graphics consumer PC these things
in advance someone
we gotta a good version working bruise
on relatively expensive hardware the
challenges are that you know
3d graphics was barely there in 1998 but
in
inspired us and made aggressive
prediction about what we thought would
happen with 3d graphics
I'm really famous for aggressive
predictions
about this license plate 1998 I'm a
technology optimist
and well known for saying things will
happen and I
made my predictions and Moore's Law I
more often right than wrong
based on random lock but I'm still doing
pretty well however
the challenge with all predictions is
timing was not until 2001
the keyhole the company was founded as a
as a a new company
but 2001 was right after the dot-com
bust
most are not true just happy to be alive
we focused on a subscription service
you without the traveling will stay
would be a good verticals go after
we operate on a shoestring budget which
really limited the amount of data which
provide
wasn't until 2003 when a chance meeting
with CNN
goddess into their mapping service
providers and put it on air
it turned out that when iraq was invaded
in 2003
in April things exploded basically our
service was
you know on the screen pi times an hour
are serviced are you know getting very
hot
we had to go to frys in by disk drives
and bring more machines in just to keep
things alive but
this really grew the awareness and put
us on the map
as it were so in April 2004
sergei was in the board meeting
discussing the I P O
everyone has maybe a story he was
showing who keyhole
to all the other board members showing
where they lived and he was pretty
excited about it
we're invited to come present a week
later in just 24 czar
24 hours after the meeting who offered
by us and we
after some thought accepted because
there's two things the Google providers
we can get anywhere else and that was
scale
an investment when it we've been
suffering a by machines fries just keep
the servers alive
you know right when we join go away said
what would you do with a thousand
sheen's
well we figured out what we do that we
were able to
set up on many different data centers
and provide a much better service to a
large number users
but the other thing we also in really
important we really look at the
proposal to buy this satellite day and
said you know why are you doing just
this way
just by it all in this change everything
because this game is World
worldwide coverage many different
countries and made from much better
experience in that one
led to the launch Google Earth free
however
even that was a challenge for Google it
turned out that in the first few weeks
we're over half the pan with served by
Google we almost
took out Google search before we got
things under control
but the ability to reach so many users
with something the only guy who could
give us
meanwhile sitting right next to us was a
team-building Google Maps
and I don't think for people fully
realize all the walls like back in 2004
web-based mapping involve waiting ten
seconds not just for the first map
but any pan and zoom you had a round
trip to the server
you members it was good to type in
different fields four five and six your
address and street and city
you know what you're searching for and
sometimes it wouldn't work
so there was several different things
knew about this this used Ajax
so the javascript running in the Browse
was able to make for a much more
interactive experience
we pre-rendered the entire world tiles
offline so we can serve them very very
quickly in this made the performance
smooth and snappy in the big thing was
we had the single search boxes
at the top this is our geo coder in and
like the ones in the past we had to
break things up
we made a single box now people were
surprised and
had to get used to this we gave me
examples right here
above the six in a six different ways to
use the service
so teaching was no big for the process
now like to talk about how these apply
to all whom as we've learned a lot in
the last seven years
in the focus we've had on
comprehensiveness accuracy and usability
are going to describe all the work that
we do on Google Maps
google has always had him session
comprehensiveness while they were
growing more and more the web
we were trying to map more and more the
world
however you know that first launch
Google Maps in 2005
actually look like this there's
something wrong with this map as United
Kingdom
Western Europe Asia South America we
didn't have it
however we wanted to launch early and
often and down here you see in the
spring I was actually sent in
it's in German because the germans one
happy with that not been represented on
the map
in 2006 and a further we were able to
add more and more countries and complete
the a
world but we still had a skeleton we're
still missing you know Eastern Europe in
many countries around the world
but by 2008 we had a world map we
license data from as many
good providers as we could find and we
had good coverage
and this was the state of the world but
on the imagery side things continue
so in 2006 after we had launched Google
Earth
we had you know much that imagery that
worry about from integer go home
but today that same amount of data is
launched every two weeks
and to both Google Earth and Google Maps
in 2006 37 percent world was covered
with high resolution imagery and today
75 percent
all people in the world can see their
house
in high-resolution
3q it started in 2007 we launched
with just five cities United States we
used five megapixel panorama cameras and
you may remember
you know look to be there is a bit low
resolution we've been improving for
years since then
and now in 2012 139 countries
we have three thousand cities covered
and we taking sixty five megapixel
panorama beautiful pictures
but we can get this review car to every
continent
getting to antarctica required me going
on a boat because I wanted to
I was going there anyway and I realize
that this is a chance to add
the final cut into Street View so I was
able to take these pictures
in a wonderful trip that I had to the
Antarctic Peninsula
so today we're also announcing we've
driven over five million
unique miles in Street View this is a
huge achievement and shows
just how much data can do to change the
world combined with all over imagery
acquisition Google now has over 20
petabytes
imagery street he was a big ambitious
project
but inspired us to even bigger one
building our own maps in a project
called ground truth RGT is we used
internally
we've been licensing data but there are
challenges with quality impressionists
and the flexibility to offer all over
ons all the services we wanted to
building our own maps gives us that
freedom we embark on a five-year mission
to build our own maps from raw data
combining errands I'll injury basic row
data and street view
allows us to make much more accurate
maps in our previous a possible
this is a example the at was to on shows
how we can actually pull out
using computer vision all the street
signs and automatically placed them
on the map in use the GPS tracks
other Street View cars to more actually
correct the road geometry
whipple able pull at Turner sturgeons
and even down here speed limit signs
and this is all part the process we'd we
use to make an incredibly complete and
accurate map
and we're working this on many countries
in the glow however
in countries where the word good base
maps and their work was in street view
we needed something and we watch matt
maker in 2008
in for for many countries this is this
is the best maps they have some Pakistan
is a
excellent example the country whose
almost fully mapped for mat maker
this is this all about and i this is one
of the best examples I've ever seen over
a four-year period
this one from a naked map to something
that's more detail than almost any
american city that I know of
so you can see here you get labels in
different languages
all the plot sir labeled we have local
business listings we have
parks areas bypass know the people
who are experts in their area really
able they're detail that is unavailable
elsewhere
in this is in Pakistan many other
countries the best maps available
through mat maker
so to wrap a comprehensiveness in 2008
with 22 countries thirteen million miles
that weird right now have a bowler hat
driving directions
it was all based on license data today
we have a 187 countries
there's twenty six million miles so
double there are navigable
we also have 29 countries they have turn
by turn voice guided me driving
directions
all possible because it was first
imagery and users for symmetry
and the coverage in Cali continues to
improve you know we're certainly not
done
or continue work on it the next
underlying principle
is about accuracy to a minor injury
we use many different computer vision
and GIS techniques to match our various
sources
aligning imagery to train is actually
one the biggest corporate affairs when
you do or the rectification
you tend to get me in pretty big
mistakes even after you iron all that
out
there's still some cases where we have
to correct
be on that and get small errors here's
an example
a group of engineers came to me very
recently after having found a set in
this line is that they couldn't explain
to any the other typical processes
it turns out the somebody in it imagery
that would received
have accounted for one very important
thing plate tectonics
as it turns out typically people map
data in their own local they to
coordinate system because
you know that things move relish each
other so most map most
GIS is done locally Google needed to map
the whole world
and so we used algorithms to convert a
different days date accordance around
but in many cases it wasn't handled
correctly at the source
or in some cases with the algorithm and
were able to detect
that you know this row data here doesn't
matter the imagery and in this case to
different sources in Madrid in line up
in a really mattered when the date was
taken
and how we corrected for the trip from
california's two and a half inches a
year
but in the algorithm can be up to me in
15 to 30 years
difference in data so things do move
around this allowed us to knock out
another source here in our data
but they're many more that we continue
to work on
against reviewers is to help correct
data we use
computer vision to pull a business names
in all sorts of information
directly from the picture we combine
this
again with human operators to verify and
validate when we're not sure
and this is that over twenty million
precise cheer codes to
to the Google Maps service
users are a great source for corrections
we have a service call reporter maps
issue
that allows people to complain about
anything that they don't see is right
in this example users gotten driving
directions &
there they have an issue with this left
turn it says it should be restricted
in the reported to us and using the tool
similar to ones that you should you
a were able to look deeply into the data
in use art Street View imagery in a very
nice
interactive method to compare its to
what these report in this case it was
very easy
you know our Street View imagery
actually confirm exactly with these were
saying
we are able to verifying published
immediately when we publish
are all users who use Google Maps get
those corrections
within a few minutes in this this
ability to quickly turn around
corrections
very powerful and what are the
advantages having a
holistic and complete database
in addition to all the developed world
makers also been launched in developed
countries like the US Canada and France
the ability to add your local knowledge
enables users to add hiking trails
bypass incorrect improve local business
listings
today we've launched and that may
continue country South Africa and Egypt
in later this month we're going to
launch in 10 your pic 10 countries
about in Europe and Australia and New
Zealand
the third element a a google map as
usability
being able to provide the power of the
data to all users
is is critical me do it in many
different services the single search box
is available
on your GMM on websearch
and provides much more than just did you
go to these days
its it behind it hides you know the
Local Business Index
driving directions the ability to turn
on traffic supporting many languages at
the same time and also the powerful
suggest features
sontag you know here's some examples
being able to work
do searches in any language about any
country
being smart about answering the question
about Paris where is it
you're looking at the whole world is
probably in France if you're in Las
Vegas
is actually the hotel but if you're in
Texas you might actually find Paris
Texas
no in context in providing the best
answer to the query
saying the user time is is all part of
the issue
I want to bring up one example here in
particular yesterday I was listening to
NPR
and there was a story about a finding
finding jobs after college graduation
and this woman who'd been a liberal arts
major gotta
was it like being an RA 1&2 also
with camp camp counselor and thought
that these experiences really good so
she thought
boutique hotels would be a good place to
go search so what did she do she
actually went to Google Maps
search for he could tell says F was able
to find ways to 13 boutique hotels
your send a resume and and within 24
hours she'd gotten a job
I can't promise that but you know it's
much more than finding a path home
finding a book business you might be
able to change your life
traffic is another example where
integrating people using Google
and search service is very important
as we were I was being driven in
Washington DC
and we just passed a fender bender and
is only a few cars backed up as we
slipped by
happened just you less than a minute ago
and I look to Google Maps it was green
right then because it was so soon within
three minutes it gone red
the ability to takes a sensor data and
send it through the server and back down
2 users
in only three minutes is an incredible
example the Google infrastructure and
the ability to very quickly
compute in return data back to users and
help
with navigation in their traffic
so we have not thousands data feeds and
one of them
is the floor plans for no buildings that
we've created
and it's not just about a picture on a
map the ability to have all the flowers
are building the ability to
say you with my location say what for my
own where my in the building
is very powerful but that's also not
enough we launched indoor walking
directions the ability to
here you from outer space per her
cure you from you know out in the world
in the building
possibly to its transit station: to take
a train and then back out
no navigating this complicated tokyo's
subway stations i think is really only
possible
with Google Maps for Mobile
so remember when I said that we or
whatever innovations was to pre render
all over map tiles in 2005
well a few years ago reverse that
decision Google's infrastructure
improved
and also networks improve were able to
render tiles on demand within 10
milliseconds
that's a thousand times faster and
experience in 2004
in this enables many new capabilities in
Google Maps in one of them is Matt in
your language
now this is Matt the United States
networks fine if if you speak English in
can read it very easily
but if you re Japanese you know you like
like something like this and so the
challenge being able to provide all the
world maps
in your language is one of our goals we
done this for several languages so far
in our land more by translation
and by technology but there's several
other features
the Google Maps API is used by over
800,000 developers and it's a service
that's continuing to grow year-over-year
this is an example love the render
on-demand tiles
the ability for whom have Maps API site
have it own
look and feel based on what he asks for
i think is really important is one of
the strong appeals
Google Maps mining that with the power
the search box and all the other
infrastructure
who was behind it the Google Maps API
extremely popular service
but now I like to talk about some other
uses have
Google Maps Google Earth Rebecca more as
they had a good workout region she has
done some incredible work
bringing social and environmental
awareness and tools to those folks
so with that Rebecca
thank you very much Brian and good
morning everyone
yes I'm had a Google Earth outreach so
what happens when you take this
breathtakingly detailed and vivid
replica
the planet and you put my hand in the
world people do amazing things
so I'd like to share with you this
morning how our
partners thousand nonprofit
organizations around the world
are using Google Earth and Google Maps
I'm to
better understand the world to raise
awareness
and even to create solutions to some of
the most challenging issues we face in
areas as diverse as
climate change environment human rights
cultural preservation and humanitarian
relief
my first week on the job
as an engineer on Google Earth team
Hurricane Katrina
hit as you might have guessed as he did
just learn from
from Brian I'm cooler than just been
released two months earlier
the US government asked for our help so
we worked
around-the-clock everyday publishing
near-real-time
imagery up the flooding and I'm actually
gonna show you
that now we're starting
on August 16th before Katrina hit but
pay attention more about to switch to
august thirtieth
you can see in the image in
where levees had burst where the
flooding was
which areas were still say as people
over those days called 911 from the
roofs of their homes
the rescue workers use this imagery
and Google Earth to enter their address
figure out how to safely conduct a
rescue get the latitude and longitude
from Google Earth
and call that information those
instructions to rescue helicopters
the Air Force told us later
that they using Google Earth they save
the lives of more than 4,000 people
so that was when many of us realize for
the first time the Google Earth was much
more than just
a fun way to fly to your home and figure
out where to go on vacation
and actually was a uniquely powerful and
meaningful and significant or
for public benefit so from that Google
Earth Hour which was born which is
our initiative to help people around the
world use Google Earth and maps to make
the world a better place
so since then there have been many many
success stories from our partners
and you can see some other featured on a
Google Earth outreach site
we received a lot of interest from
people in organizations who not only
want to use our maps
but they actually wanna put themselves
and their stories
on our map which is the world map so for
example
take chief Almir he's the indigenous
leader other tribes in
the Brazilian Amazon in 2007 he was the
first member has tried to go to
university
and in an internet cafe he stumbled on
Google Earth
like most view the first thing he did
when he tried to go on earth was he flew
to his home
which you can see his territory is
surrounded by that read boundary
he was shocked because what he had
he couldn't appreciate from the ground
what you can see from the air
that their primary beautiful rainforest
territory
is completely surrounded by apocalyptic
devastation and even in our satellite
imagery
you can see the areas where illegal
loggers were making incursions onto
their land
some which he had not even known about
so he came in he asked for our help
to put his people literally on the map
to help defend their territory he said
the time had come to put down the bone
marrow
and pick up the laptop so we did a
in 2008 we literally took laptops to the
Amazon
to help them go from the Stone Age their
first contact was 1969
from the Stone Age to the Internet age
we gave them workshops
on how to take photographs videos have
the young people interviewed the elders
and put that information on Google Earth
there now layers
that they've created that help the
sooner we in the world visualize the
sites have illegal logging
where they hunt where they fish where
they gather medicinal plants
the first contact with the outside world
this is an example this is just the a
snippet
on what's coming very soon from them I'm
this is I icon that marks our historic
battle
know what we've learned through this is
that just as language as an expression
of culture
maps are an expression of culture we put
the site up gettysburg on our map
now the sooner we are putting their
battles and their their stories on their
map
it takes the concept have preserving
their land
and their culture and makes it much more
tangible to people around the world
cheapo me actually told us that in their
language to be Monday
the sooner we people call Google rug Aug
mark on
which means messenger think about that
so today I am excited to also finally
announce that
are on our news partners the halo trust
is today
arm announcing an unveiling
their work using Google Earth to
illustrate an advocate for their cause
the hell trust is a non-profit
organization dedicated to eradicating
land mines
across the globe and they've launched
this project called explore
a minefield the group is using Google
Earth
to track landmine clearance operations
demarcating areas
that are too dangerous to walk
identifying land mines for removal
and then marking the areas that have
become safe to return
you can see in a green the areas they've
cleared and the redder areas
still to be cleared
to give you an idea of the performed
after in Google Earth in 2002
you can see the area con J in angola
I had these minefields but by the time a
2011
they had successfully clear those mines
and these areas were now safe to return
so why is this so significant
just for that one region I showed you in
Afghanistan once halo had cleared the
mines
more than 70,000 displaced people could
return to their homes
children can walk safely to school the
locals were again
planting wheat Nationals and grapes
this is a snippet I've their Google
Earth war they just launched today and
you can read about it in a lat long blog
post
is an area long on the border between
Cambodia and Thailand
more than two million mines are located
in this area that they're working on
removing
innocent lives are being put in in peril
are and i buy these enemies essentially
they can strike at any time
halos goal is by taking
abstract information and putting it on
the map and making it more vivid
they'll raise global awareness and
support for this humanitarian cause
so as I hope you can see something as
simple as
a map can be a uniquely powerful
and meaningful way to bring to life
these stories and these causes
people in organizations are changing the
world simply through the ability to
access
and contribute to this map we found
that they can unite people's and nations
toward a common good
thank you very much friend
thank you very much Rebecca records
Earth outreach team inspired is a Google
to continue to improve the capabilities
Google Maps and improve its impact on
society
in May removing incredibly quickly and
we launching
you know large was to feature shown here
and Google
jeered he was really incredible rate and
that's where we are
but it's still early days we're excited
about the progress and now I wanna
talk about three new demos to ensure
share with you and first
research and a product manager from
Google Maps for Mobile we present a new
feature
Google Maps thank you we did
thanks brian good morning everyone
since we launched Google Maps for Mobile
back in 2005
there's always been one key requirement
interacting with our map
an internet connection and because of
this
people would often still carry around
paper maps just in case
for instance when traveling
internationally without a data plan
or when tom underground in the subway
well today I'm here to tell you you will
no longer need those paper map
like many other Google App Google Maps
is going offline
this has been one of the most requested
features and is coming soon
to Google Maps for Android we think of
my master really brings your mobile
Matic
maps experience full circle by providing
you with
million Google Maps always in your
pocket whether or not you have an
Internet connection
so let me show you how this works
couldn't coolly please switch the
projector
great select their you find yourself
traveling to London this summer
and you'd like to make sure you have a
map available at soon as you land
well before you head off simply find the
area
that you plan to visit on Google Maps
and select make available offline from
the many
you'll notice that we're estimating the
amount size that
this map will take seeking get are rough
estimate
how much space this'll take on your
device and plan for any
data charges if you're on a metered are
capped wireless plan
want to confirm your selection the map
will automatically start downloading
onto the device while
downloading let me share with you the
most
the biggest benefits of I'm at
if you have GPS enabled on this device
the blue dot will still work
it's like a digital you are here: marker
that follows you as you move
and if you have a compass on this device
you will be able to Korean yourself
without 3G or WiFi
making the experience truly better than
paper
so it looks like london is just about
outmoded
onto my device though let me show you
quickly what the experience will be like
when you're offline and to do that
I have another tablet here where I have
not saved London
and ultimately being offline by putting
both tablets into airplane mode
so let's start with the tablet that does
not have the math saved
this apology this would be your
experience today if you are using
MobileMe
and as you can see the mat may be clear
at this zoom level
but as I get off the plane and start
doing in United that
the map is virtually unusable because
the streets are not clear at this level
now as a comparison the device for we
have just downloaded
the Google map and you can verify that
we are in airplane mode
as a start zooming in the map remains
clear
even down to street level see you can
easily see where you are and where
you're going
could police with backslide
the ability to provide of I'm at is just
another benefit
building are on global base map
so next time whether you're traveling
internationally
or underground we hope offline maps will
help you get around
look for offline maps coming soon to
Google Maps for Android
now that we share that bit of news it's
my pleasure to introduce
Luc Vincent engineering director first
review
thank you retire and good morning I am
so was buy explains Google Maps new
rates many layers on information
and one other than is stood you and I'm
YouTube
any but the next evolution in Street
View technology
before the National deleted history so
why joined Google
what is now known as to you was my
twenty percent project and
I'm very pleased to have taken so far
but in truth he was not even my idea
the idea of us should you came from
Larry Page RC himself
who before I even join Google had to
take on a camcorder
and driven around the bay area and I can
run stand for truth few hours
to content until his car and given the
material into
computer science professor along with
some research funding to push drug
research in this area
he believes strongly that it was good
information a street-level
that we made useful tool users at scale
and a
in the right benefits a Sola
to make this happen in the early days of
the project
we build a few fans like this I you
can't it's that little monster is good
102 found requirements
many many cameras lasers computer rack
in the back
batteries GPS what have you so
with these vans I worry bout you a
driving up to capture a few cities and
we'll we used imagery
too long should you about five years ago
and run some
however those that do not very reliable
too many things can break
at and given time so over the next few
years we've been working
to improve our technology to improve
their love you too can rise the
resolution
and after a few to rations this is with
the card like today
Morris a you notice in the tub this
15 Lance soccer ball looking camera
those panoramic
you on your route sixty five megapixel
resolution
the Denver rival and we've deployed
those
and other cars other malls around the
words
and as Ryan said we have captured five
million by the road
now an adult or yours are however
you can't go everywhere we scars and
we soon realized that in order to
capture some the worst the words must be
four sites
we had shoes in fact do something
different so we've been
for strikes was actually we took all the
equipment in the car
major shrinkage them through them to BG
tricycle
and we've taken those choose a number of
amazing and unique place in the world
like UC campuses like one who decides
like amusement parks and what-have-you I
am
week even got great even occasions and
we put those
on boats like you see on the left your
the trike on a boat in the Amazon River
recently were also produce a tricycle on
a train
in the Swiss Alps and kept on Hwy train
truck that happens to be ordered site
I am we r 12 step brother
now in 2010 when we decided to put the
equipment on snowmobile
and captured the in this case the
Vancouver Olympic sites
we had a number issues with vibration
and was a
cold temperatures that caused him to be
a reliable we
record I'm solve them and were emerge
you actually take this
snowmobile to number ski resorts and
gorgeous places again
run the warm so this again a quest to be
comprehensive
on but
even more recently on we get involved in
a
the Google our products where this time
we want to you
our users the beach in ninety gate
museums virtually
and you do this we trunk they've been
even further
and were able to bring on one good the
trolley I would you see here
on the left it's as you likely pushcarts
with a battery computer screen
the same camera and again with this run
museums
or large indoor spaces and with %uh
we've taking this to you the on the
order of 50 museums worldwide
and and cause growing and and this is
Benjamin a launching the grill our
product
recently which was a second-generation
so you ask what next
well let me show you what's next I I
would put them on your
here's
fears or because the trucker went to the
gym for them argument
your ego so
menu in the video
so obviously lot of places with a
gorgeous miss in the world
John you walk to right so to do this
we love the trucker willing to shrink
equipment even further
you and everything together into one to
reform package
this is on your for under forty pounds
includes June a
lithium-ion batteries that can carry for
the whole day
I am is gonna minicomputer is
android-powered
I am you Android phone that parent
so this in concert go all day we intend
to take it
to a number of other national parks you
to Grand Canyon
to new steps and Buford places like
castles and ruins I really
I'm interesting the to Venice were you
know you might mission to YouTube gonna
lies as well as on the the narrow alleys
for over the place
so it's really are next evolution we
want this to be ever to take
imagery in places where you only dream
I'll visiting I even took this recently
I am skiing this with its quarterly
just a test equipment yard sale the
skiing and it's really not so bad
I am you know you gonna be a bit careful
obviously but it works
i cant so I was the acute in a few
minutes they're here
was using GoPro camera instead so our
said well you know
after you asking for a few hours with
this news from AP joining you small and
mid mounted camera
the but obviously with this you can get
far greater resolution
for a quality and we hope to users
and what he was partners as early as
this fall on the even sooner
got your whole bunch of places and bring
imagery that
you've only dreamed of a i've seen
before so with this I would deduct
to your cheap YouTube urge far financed
by the day
thank you future
thanks Luke so we talk today a lot about
what it takes to build a map that is
comprehensive accurate and useful
but now induced talk a little bit about
the work
that we've been doing on the Google
Earth team to bring
the next dimension map which is 3d and
somebody give an overview of what we've
been doing
and a peek into the future so
that seems to be a lot history lesson
today so I thought I would do the same
arm earlier Brian showed the shot love
keyhole
this is the technology that I was
acquired by Google on is found its way
into all over mapping products including
Google Earth and Google Maps
on and hear the 3d that we have
is terrain data and this works really
great when you're trying to model the
Matterhorn because it's really large
I it's a great way to represent natural
features
but when it comes to a cityscape you get
these buildings that is kinda
are flattened down on top of the terrain
and it really looks a real I and doesn't
really give you any sense at all
what that this place is like by 2005 we
started to introduce our first three
buildings
and here we basically took the
footprints in billings
and extrude them up to the high to the
building and so for example here
in New York City you can start to get a
sense of the the grandness at the
buildings and I
in New York City here but by no means
does actually
make you feel like you're there in 2006
we introduce our first
photorealistic 3d models so here
actually taking
actual images and texturing on inside
models
and this does a great job for showing
detail
off select landmark buildings so here
for example is
san Cisco City Hall off in the distance
there's Transamerica building
yeah in just kinda not much else in
between see had to serve
desolate landscape that a that really
just
leaves you wanting more by 2008 we've
really ramped up our ability
to get more 3d models arm in here so
here for example is a
Shana same Cisco we have I'll lots in
different bombed buildings
so in in urban areas like this in urban
cores and same Cisco New York and other
places
were able to get a pretty good coverage
I'm to the point where we now have
millions have models and
dozens of countries around the world but
they're some issues here
for one the imagery in the tears coming
from multiple sources
I'm it could be earlier jury could be
coming from a user model
in some cases it might even be a
synthetic texture that doesn't
represent the actual image it all and so
it creates some
inconsistency that this doesn't look
right also
not every model is actually or every
building is modeled
and the gaps also kind of break that
allusion
I finally you can see that we still have
3d Billingsley he can see quite our the
be %um it is still lay down on top of
the train
even though we have three mall next to
it so
we knew we wanted to do something better
and
we want to do something that would be
comprehensive
something that would be consistent and
something that we could do at scale
that would allow us to work towards our
goal of modeling the world in 3d
so how we can do about doing this
so what we're doing is we're using
automated technology to extract 3d from
aerial images
now this isn't a new idea this is
something we've actually been working on
for a number years
but the quality just wasn't really there
I to meet the standards for Google Earth
that is until now so let me describe how
this works
so the starts with planes the planes are
equipped with custom
Google design camera systems where
they're actually gathering
what we call oblique imagery where we're
taking
these 45 degree angle shots from each
other cardinal directions
and directly down so that we can get
each side
are structures in an area to make sure
that we have what we need
actually create an accurate model
then the plane's are flown in a very
tightly-controlled pattern to make sure
that there's a sufficient amount of
overlap
so that we can get a complete picture
and
be able to represent are large
metropolitan areas
so ima we do is we use a technique
that's called stereo photogrammetry
to extract the 3d model from the
multitude images that we've collected
so here you can see again a San
Francisco City Hall
and this is actually reconstructed from
just the images that we've taken all
these various different angles
and I mean almost looks like an old clay
model but in this case disclaim all has
been sculpted by technology
rather than by Hans
so the next step is we actually
for each point or pixel on the model we
have to find the best possible
color or image to match that point
and we go through the collection and
this multitude images we have
to find the best one for each location
and we generate what's called a
textured 3d mash and this is basically
the building block
that is necessary for a 3d graphics
system to be able to render a 3d scene
like this
so it's great we have this really
beautiful detailed model
we're still not done because we need to
be able to
producers and serve it in a way that can
reach oliver users wherever they are in
the world
and so to do that we have to package up
information in a way
that is efficient to store and serve
transmit over networks anywhere in the
world to whatever device is our users
are using to look at this data
cell you know all the serious great
there's nothing like seeing a real
product
so I'd like to show you that now so if
we could switch to the habit please
so here we are again we can see that
we're
at San Francisco's City Hall and this is
a beautiful view
and it looks like I'm just hovering
about it taking a photograph but what
I'm actually able to do here
is interact with this
just by twisting my fingers and you can
see
now only is City Hall a beautiful model
but everything around it is modeled as
well including all the surrounding
buildings
and even the trees and landscaping and
the consistency of this
really does crate that delusion that
you're flying over the city
let's do that now some sticker
a little flight here along Market Street
again they'll notice that
every single building here is completely
modeled
and and that's important because we're
trying to create magic here we're trying
to
create that allusion that you're just
flying over the city
almost as if you're in your own personal
helicopter
so here we are heading towards downtown
and
let's just spin around down to the Ferry
Building
so Google Earth is a fantastic tool
for people build explore the world but
what are the challenges we've had as
it's been difficult for people
to be able to go in and explore
the world in 3d and to discover new
things
so when I wanna show you now is an
example of a new UI that we have
are the recall the tour guide which is
really a way for people to
search and explore I areas of interest
that night when I find
so for example here were back in San
Francisco
animus gonna sway this or to the side in
OC that there's a
allister various ventures that I might
wanna go explore so maybe a Giants fan
slits go check out AT&T Park it's one
more second
this is a technology demonstration zone
all right here we go
so again I want to come in and check out
AT&T Park
will take a flight and now I actually do
a circle around the location
again here giving a great sense have
what this location is like and then to
finish list sister
fly along the Embarcadero here
here we are back at quite our but you'll
notice that now
everything in the landscape is modeled
in 3d I
really giving in that sense that you're
there can we switch back to sites please
so
and you can see this is just a sneak
peek out some other technology that we
have available
but I'm proud to say that in the coming
weeks
we're gonna bring this new 3d imagery
and the first
a bar metro areas modeled in 3d to both
Android and i OS devices
and given that we really want to make
sure that we model
you know the whole world to the point
where everyone can %ah
can be able to see their own communities
we're gonna be bringing
I we expect by the end of the year that
will have communities over 300 million
people
modeled in this new technology thanks
very much
back era thank you very much better
so the obvious question is
when wall the 3d imagery be available on
the rest Google Maps services
and I i think this this example actually
points out one of the challenges that
different vices have different issues
the ability to carry
power 32 JavaScript or to them variety
of a 3d graphics drivers
that you might run into is is one of the
challenges that the key on Google Earth
and in any 3d developed ap faces over
time so
our goal is to get everywhere and it's
just a matter developing the
doing the process carefully so we've
been able to
bring google map services to a lot of
people today we're announcing that with
over one billion monthly active users
for all cool map services and this is a
very big number four is what it means is
that
as we've been trying to create a map of
the world we created a map
for the world as I said I'm a technology
optimist
going from the domain Hollywood studios
to anyone with internet connection being
available in my pocket
is something that you know even the on
my most optimistic predictions
I'm so happy to see it that it's
happening I've been working in 3d and
mapping technology most my life
as an industry we made more progress
more quickly than I imagined possible
and we expect innovation to speed up and
even more over the next three years
what we never will create the perfect
map we're gonna get much much closer
than we are today with that like to say
thank you
and we're ready for a Q&A so
I just wanna dance that
