Chikai Ohazama
Project Manager, Google
Earth
Chikai Ohazama
has watched the software program he helped design become a worldwide phenomenon
that made high-resolution satellite imagery available to the average person. He helped bring Google
Earth to life as a founding engineer at Keyhole Corp., which Google purchased in 2004. Now as Google's project manager for Google
Earth, Ohazama's job is to evolve the product.
Given the competitive nature of the
business he is close-lipped on some of issues regarding the company's future.
He declined, for example, to say whether his business unit, which includes Google Earth, Google Local and Google Maps, is profitable, how much it invests in its
archives or whether the company will continue to acquire new companies, as it
did in March when it purchased @Last Software, the maker of the 3-D software SketchUp or follow in the acquisition footsteps of
competitor Microsoft Virtual Earth, which in May bought the remote sensing
engineering services company Vexcel Corp.
What he will talk about is the product and how the
company intends to make Google Earth even more 3-D, concentrating on getting images of locations not
only from above, but also from ground level. Google Earth also plans to rely
extensively on its user community, to come up with unique
overlays or customized uses for its products.
Ohazama
discussed these and other issues recently with Space News
staff writer Missy Frederick.
How far are you now in terms of world
coverage? What are you projecting to achieve?
Right now, we have sub-meter
coverage of about 20 percent of the land surface of the Earth, which accounts
for about a third of the world's population. We have the entire Earth covered
in terms of Landsat data. I can't say anything very
much about what we'll have in the future, but we're working to be the biggest
and highest-quality database in terms of resolution and currency of coverage.
How updated does Google Earth plan to be in terms of its imagery currency?
Right now much of the imagery seems to be around two-years old.
I guess the
average will probably stay around that, or perhaps a bit older, though we will do
our best to keep things current.
How do you see this
product changing and expanding?
From a
bigger perspective, we want to capture all different dimensions of imagery.
With our purchase of Sketch Up, you are going to see 3-D models featured
even more. We're also stressing featured content, such as the overlays we've
developed with the United Nations Environment Programme and
the Discovery Channel. Not only will our base layer of the world exist, but
also content that is put on top of it to add variety and diversity.
What are your plans for
acquiring data and new content? Are more mergers in your future?
There are two ways of doing this. We can acquire data
through commercial sources, but the community effort is also very big. There
are companies with warehouses of data who are contributing data for free -- this
is particularly relevant for the 3-D data that we're acquiring.
The best data source for us right now is third-party
efforts -- we might be annotating our coverage of San Francisco, and someone
will submit photography of a great bar downtown. This will probably continue
for awhile. We think very much in the global perspective of the entire Earth.
What is the
relationship between Google Earth and Google Maps, and how is it evolving?
They address different segments of the population in
terms of usage platforms. Everybody has a Web browser, and this is a much more accessible way
to get access to imagery technology. But there are interesting match-ups that
are going on -- you see all sorts of housing maps that use Google
Maps as a springboard to display their content, for example.
Do you have any plans
for additional featured content in terms of overlays?
We're
planning on making featured content something that always gets refreshed on a
regular basis. We're getting contributions all the time from different people --
one community produced a layer that displays all the lighthouses that exist in
New Zealand and their locations.
What is the business
model? How do make money? Is your revenue going to be
primarily advertising driven or based on customized products for business
customers?
We have
forays into both right now. We have an enterprise product that allows our data
set to be put to use in particular corporate environments. And we're playing
around with advertising to see how best we can do that with the Google Earth algorithms. We want to provide advertising in
a local or geographic way that is still tasteful, and provides the maximum
benefit to the end user, instead of something that's just looked at. We've also
done a little bit with pop-up advertising with Google
Maps, and you'll see different things coming in that sense.
From the enterprise side of things,
we have a fair number of clients. I can't say how many, but it is a large
number, some of which we acquired through Keyhole, but it's grown a lot. A lot
of our customized products tend to be things like government agencies or real
estate firms - people who want their people to be able to have access to this
kind of information from any laptop, or have the tools to upload it to any
desktop.
Have you been working with the U.S.
government and do you have any plans to do so more in the future?
We have a
close relationship with the National Geospatial-Intelligence Agency and the
government. We definitely have taken our technology and tried to figure out how it can be applied within that
environment. Right now our relationship mostly consists of listening to them
when we develop new stuff to make sure that we're addressing their needs and
including the features that they're asking for. I think our relationship will
continue to grow from there.
Would Google Earth ever consider building its own satellite or
acquiring a satellite imagery provider? How do you see your relationship with
imagery providers continuing?
Right now,
what we're doing has been very successful. We've had a great relationship with
Digital Globe, and with others, such as small towns who contribute imagery to
our database. Everybody wants to make sure they contribute,
and I think that aspect will help us grow to have the best data set possible.
As for building a satellite or
acquiring a provider, we'll see what makes sense technologically and
financially and whether we'd want to pursue those elements. But we're open to
new ideas at any time, and as time goes on, we'll see what happens.
You recently started a Google Enterprise Program that's designed to bring together
developers, vendors, etc. in order to develop value-added services for Google products. What does Google
bring to the table in this kind of partnership?
Most of
what we bring to these people are accessibility. We're
taking technology that's very hard to understand and making it so anybody can
load it up and make use of it. At a recent remote sensing conference, everyone
was coming up to me and telling me how their seven-year old uses Google Earth. The
fact that people as young as that can actually use
[geographic information systems] GIS technology is one of our high
leverage points, and other vendors can use that in order to customize to their
particular needs.
