Christopher Tucker
Senior VP, ERDAS
SOA will invert
productivity paradigm
How do you see
your company
and the Indian
Defence sector?
ERDAS has a long history
with the Indian Defence community.
We have a large customer
base and support a variety
of operational groups. We
are aware of the mission
needs and challenges across
the Indian Defence community
pertaining to imagery management,
data management,
Defence Spatial Data Infrastructure
(SDI) and look forward
to providing support on
all these fronts. The technical
presentations made on LiDAR,
geovisualisation, etc. at the
recent GeoIntelligence India
2008 conference show the
maturity of the knowledge
base of the Indian Defence
sector, which is similar to what
we have encountered in the
US. Most of my interactions
with the Indian Defence staff
have been with regard to the
areas where they look to
industry solutions for their
specific needs.
What is the
'Bounding Box'
problem we are
facing?
I come from the service oriented
architecture (SOA) side of
the business. People talk a lot
about geospatial exploitation
and geospatial analysis. And
they have just started to think
about how they can get all
that data to the right people,
at the right time and the right
place. If you have an SDI, any
user, at any level across any
organisation can simply use a
bounding box query to discover
and marshal all the data,
regardless of where it is in the
network and which organisation
owns it. Currently, people
spend 80% of their time trying
to find data, access data and
get data into an application.
Approximately, only about
20% of their time is given to
the real analysis or operational
support activity. With SOA, we
are trying to completely invert
the productivity paradigm,
where you spend 5% of your
time discovering data and
marshalling that data into your
application. The rest 95% of
your time can be spent on
doing your work. That's the
essence of the Bounding Box
problem. As we invert the productivity
paradigm with SOA,
people will see the reduction
of mission latencies and the
technology infrastructure that
provides these benefits will
become transparent or visible
to the use. The scenario is
similar everywhere.
Are there specific
needs for Defence
that you are presenting
to the OGC?
The notion of a Defence SDI
has always been an important
topic in the OGC. Getting the
right series of specifications is
important. There is not just
one standard; it is a sweep of
standards that enable the
vision of SDI. In the OGC, we
have a Defence and Intelligence
(D&I) Working Group
where people from the US
and outside come together
and discuss Defence use cases.
We realise that many cases
are similar to commercial
use cases, but there may be
specific needs for precision or
online processing that start in
the Defence community that
also become needs in the
commercial sectors. In these
instances, the needs may not
be specific to Defence; but for
Defence they are more acute.
At the working group on D & I,
individuals come together and
articulate their needs to solve
the problems as a community,
developing standards-based
architecture that benefits
everybody.
Why is a Bounding
Box more than
an SDI?
A Bounding Box is just a different
articulation of SDI. SDI
has been around for years and
people continue to be interested
in having the infrastructures
built and in ensuring that
their investment supports their
activities. There are some that
are interested in the productivity
gains of an SDI. In
Defence, there are huge
amounts of 'Mission Latency'
that often prevent accomplishing
tasks on time. An SDI
allows, if properly implemented,
the ability to draw a
Bounding Box, discover and
marshal data for productivity
gains. So often, when people
state that they need SDI, it is
really a bounding box problem.
Will Wiki/social
networks be
the future for data
creation?
I definitely think so. There is
an ongoing concept of Web
2.0; and we have already seen
the transformation happening
on social networking sites. We
have also seen the power of
dynamic communities built by
individuals with shared interests.
Similarly, an SDI is built
around a community of users
with shared interests. As
these users seek to contribute
data back into the SDI, there
is the need to tie the
user/contributor to his/her
data. This requires Wiki-like business rules and transactional
audit, which create a
social network. By taking
social networking technologies
and Web 2.0 like wikis,
you introduce the ability for
people to organise SDI
dynamically. I think that this is
one more opportunity to experience
productivity gains.
What is the status
of the ERDAS
TITAN Network?
ERDAS TITAN is a synthetic
innovation, venturing into the
social networking space.
Things like instant messengers,
MySpace, wikis and
mapping applications through
mashups, have been combined
to address this growing
interest. The core technology
is a Geospatial Instant Messenger
and our Geohub proxy
server, where any human on
earth can have geospatial data
on his or her computer and
can share it with anyone
through Web streaming services.
This allows the users to
retain control of their data. For
example, you are not sending
a 2GB image, but I can construct
a personal space on
ERDAS TITAN (called
MyWorld) that reflects my
interest and my knowledge. I
can share it with anyone in the
social network so they can
pull a layer from my desktop
and add it into their MyWorld,
or I can switch to their
MyWorld. It is very different
from other data sharing solutions
in that you build and
maintain your own personal
space and are able to maintain
ownership of your data.
People continue to adopt
ERDAS TITAN for their data
sharing solution in unique scenarios.
State and county governments,
as well as private
organisations could use
ERDAS TITAN for emergency
response and data management.
In the military sector, a
commander would use it to
gather shared data to determine
if there is existing data
to conduct an operation. We
continue to learn about new
use cases as we discuss
ERDAS TITAN with potential
customers.
