Adena Schutzberg
As members of the geospatial community, we rely on a wide variety
of sources to keep up with technologies and services that underlie
our work. We consume print and electronic publications, examine
advertisements, listen to conference presentations live or on
the Internet, and talk to peers in our local areas and at national
and international events. We also interact with the vendors
of products and services. This month’s Technology Showcase offers
yet another approach.
In keeping with GIS Monitor’s mission to help you “make sense”
of the geospatial marketplace, we’ve taken the “potential customer’s”
side of the relationship and asked the vendors to respond to
some rather pointed questions in order to put their offerings
in context. We offered vendors six questions having to do with
technology, misperceptions, user awareness, and so forth—in
essence, questions about who, what, when, why and how—and asked
them to select three to answer. We asked that they limit hype
and focus on education to help their offerings “make sense”
to you.
I’m pleased to report that the responses make for interesting
reading. They also provide a firm foundation to further explore
these organizations, should you be in the market for these products
and services. Finally, these Showcase “interviews” are designed
to help fill in knowledge gaps we all have in such a broad marketplace.
Trends in Imagery
Earth imaging is becoming a requirement for more and more geospatial
projects every day. Those looking for data run into a host of
questions at the start: Aerial or satellite? What resolution?
What type of sensor? Film or digital? How will topography be
included? What delivery format? How will the data be delivered
to end-users? How should it be processed?
Being an “educated consumer” in the imagery arena is complicated.
Unfortunately, some aspects will not get easier. However, some
trends in the industry may make the marketplace appear a bit
less intimidating.
Consolidation: There are hundreds of aerial imagery companies
in the United States. Can the marketplace sustain them? As technology
and digital sensors make turnaround times faster, individual
companies will be able to do more work, perhaps squeezing the
same amount of imagery delivery into fewer, more efficient players.
The other big push factor here, of course, is the challenging
economy.
Compression: Compression technologies make it possible for more
imagery to make its way to more places inside or outside of
an organization via an intranet or the Internet. This should
also enhance previewing options for potential buyers, helping
insure that the correct imagery, at the correct resolution,
is selected for a project. Once the imagery is collected and
processed, its delivery should be faster, too. I can imagine
situations where specific tiles are delivered electronically,
while the “rest” of the database follows in via “snail mail”
in DVD format or on an inexpensive hard drive.
New Ways to Share: Just as data services are beginning to pop
up that provide “as needed” access to vector data for Web applications,
imagery services are growing, too. NASA’s Global Mosaic is under
construction and will provide full resolution Landsat 7 from
year 2000, for the entire globe. Expect more offerings from
both the public and private sector.
More Satellites: Smaller, cheaper satellites may in time mean
more imagery for everyone. For example, the Disaster Monitoring
Constellation’s four small satellites should all be in orbit
as you read this. At 90kg each, the satellites will provide
32-metre multi-spectral imaging, covering 600 x 600km areas.
The bottom line however, is that keeping up with technology
means that vendors, technology writers and technology users,
all need to do our homework. I’m hopeful that this Technology
Showcase will provide an interesting contribution.

LIZARD TECH
LizardTech Software creates software solutions and tools that
make high-quality digital content easier to capture, store,
share and use. The company’s innovative solutions make business-critical
information available instantly over any network on any device.
LizardTech is a private company, formed in 1992 to build valuable
business solutions from technologies created by the world’s
leading research organizations including Los Alamos National
Laboratory (LANL) and AT&T Labs. LizardTech software is
installed on millions of desktops and integrated into a wide
variety of platforms and applications. LizardTech has offices
in Seattle, London and Tokyo.
What type of problem/need does a typical customer bring to
LizardTech?
Users of imagery in geospatial applications have long been familiar
with the unique benefits and challenges presented by high-quality
aerial imagery. Geospatial imagery tends to be very large in
file size—and the better the resolution, the larger the file!
Working with and distributing massive raster images efficiently
inside of desktop or web-based image analysis and GIS applications
can be a data and time management nightmare. In the past, many
of our customers got around these issues by resampling the imagery
to lower resolutions, breaking mosaics up into smaller more
manageable tiles, or simply not distributing the images past
a core set of users. LizardTech’s MrSID technology solves all
of these problems through industry-leading compression and selective
decompression features making massive geographic images instantly
useable in virtually any working environment. Our customers
can derive more value out of their investment in imagery on
each project and share that value with more of their working
teams.
Why might potential customers be apprehensive about buying
LizardTech products? Why shouldn’t they be?
People are apprehensive about anything that may mean a change
in workflow or formats, and they sometimes have concern about
proprietary file formats. However, proprietary formats are not
really the issue: the issue is interoperability. If every software
application can seamlessly use a file format, then there is
no real difference between a proprietary format and a published
format. The MrSID image format is supported in nearly every
GIS and CAD package on the market, with the latest generation
of MrSID technology rapidly gaining support as well.
The geospatial community as a whole is working towards improved
data interoperability for all types of geospatial data through
industry groups like the Open GIS Consortium (OGC), which are
addressing areas like client/server workflows, and standards
groups like the JPEG 2000 committee, which is defining a standards-based
wavelet compression technology. As a leader in both of these
areas within the Geospatial community, LizardTech is committed
to driving further standardization and developing solutions
built on these new standards. LizardTech is working with our
partners in the industry now to ensure that when the geospatial
community is ready to move to JPEG 2000, their applications
to create, use and distribute JPEG 2000 files will be fully
functional and interoperable.
What one question will help clients determine whether they
need LizardTech products?
Would you like to increase your efficiencies in working with
and sharing raster imagery, and be able to use more imagery
at a given time? If you do, MrSID technology retains the image
accuracy both geometrically and radiometrically while dramatically
decreasing on-screen rendering time. MrSID files are also read
natively by nearly every GIS and imaging software available
on the market so you can be up and running immediately. And
we are continually improving on our core technology: the latest
release—GeoExpress with MrSID—supports lossless encoding and
about a 50% decrease in file size for visually lossless compression.

GEOVANTAGE
GeoVantage Inc. is a private information technology company
specializing in digital aerial imagery using GPS, Inertial Measurement
Units (IMUs) and a 4-band digital camera configuration. Although
GeoVantage Inc. is a relatively new company in the world of
remote sensing, it was founded by individuals with extensive
histories in the remote sensing and computer science fields.
This experience is reflected in 22 of the most advanced sensors
found in the market today. Extensive geographic coverage and
timely delivery makes GeoVantage a universal solution for even
the most complex remote sensing needs. GeoVantage imagery is
used in agriculture, urban management, forestry, mapping, emergency
response and other industries require that accurate, detailed
products and quick turnaround.
If you could educate prospective customers about one thing
before they contact you, what would it be?
We would emphasize that digital imagery is the way to go. The
advantages of digital products are well documented today; there’s
no reason to go “back” to film. The advantages of digital imagery
include: increased color depth, automated georeferencing of
images from data captured by GPS and IMU during flight, and
cost-savings because it can be reused and stored on hard drives.
The fact that the imagery is collected and delivered digitally
plays a key role in our turnaround time. As one of our clients,
who previously used conventional film-based aerial photography
put stated, “…Since digital imagery can be shared and communicated
throughout the organization much easier than hard copy photographs,
it has proven to be more expedient and efficient all around.”
Why might potential customers be apprehensive about buying
your product/service? Why shouldn’t they be?
GeoVantage is a fairly new player in the digital imagery marketplace,
but we are not new to the imagery business. We have solid experience
from years of work at TASC (now part of Northrop Grumman), Siemens,
and Polaroid. We have Stanford and MIT professors on our board
of directors. In fact, GeoVantage was started as the two founders
tried to learn from earlier missteps in imagery. They decided
that the best way forward was to automate more of the process,
keeping costs down and quality up. That’s been our guiding principle
and it has served us well.
What one question will help clients determine whether they
need GeoVantage services or products?
Do you need cost-effective, detailed GIS-ready imagery
with quick turnaround? Nearly every type of GIS user can benefit
from imagery, whether it’s for delineating areas to increase
or decrease fertilizer use or updating infrastructure maps.
There is sometimes a concern that a job is too big, or too spread
out for aerial imagery. Digital cameras and advanced navigation
tools allow us to cost-effectively cover large contiguous areas
as well as small distributed “pockets” around a county or state.
What’s more, turnaround times are quick because so much
of the process is automated.

PCI Geomatics
PCI Geomatics is a developer of Geomatics software (geographic
modeling, measurement, analysis, and output)
and solutions based on its remote sensing, digital photogrammetry,
spatial analysis, and cartographic editing programs. The privately
held Canadian Corporation has headquarters in the Toronto area
with second facility in the National Capital Region of Ottawa.
PCI software products and solutions are distributed through
a direct sales force, international resellers, and third party
developers. Founded in 1982, PCI Geomatics began building and
shipping geomatics software when the industry was still young.
Today, with Geomatica 9, PCI Geomatics provides all the imagery-centric
geomatics solutions necessary to meet the expectations of a
large and expanding industry. PCI Geomatics is continuously
driven to make new and better applications for the geomatics
world. We know that this is something that the industry needs.
But more importantly, we also know that this is something that
today’s customers want.
What type of problem/need does a typical customer bring to
PCI Geomatics?
Customers who approach PCI Geomatics typically present three
main issues. First, they identify that they are using digital
satellite imagery, aerial photos, and/or digital spatial data,
and need to work with this data in a more productive and professional
manner. Second, they require geoprocessing capabilities that
produce highly accurate results—results that can be used to
accurately represent the world for planning, development, or
for other purposes. Finally, customers need to be able to extract
and apply the necessary information from their imagery, either
to use directly for decision-making or to transfer to a GIS
for analysis and action support. Given these practical work
needs and the diversified range of user types who are rapidly
adopting geomatics technology solutions for their geospatial
purposes, the biggest challenge facing R&D departments is
how to make the newest geospatial software flexible as well
as capable and complete—for remote sensing, GIS, photogrammetry,
and cartography.
What is the most common question prospective clients ask? What’s
the answer?
PCI Geomatics customer representatives are frequently asked
whether we support a particular satellite or work with a particular
data type. “Can PCI Geomatics software read/write my Arc/Info
data?” “Does Geomatica 9 support JPEG 2000?” “I use Hyperspectral
Image Data—does PCI Geomatics software accept this?” “Can your
software perform rigorous model corrections for IKONOS, SPOT,
EROS, and QuickBird satellite data?” The answer is always
‘Yes we do.’
All of our products open and work with more than 100 file formats,
and PCI Geomatics clients in most disciplines appreciate the
built-in data source flexibility for their work. Efforts to
anticipate, plan, and maintain this advantage have required
resources, but have created an encouraging reputation and a
long-term competitive advantage. Broader use of geospatial technology
and the market’s growing interest in single-load software solutions
like Geomatica indicate that diversified format support will
continue to be an important consideration for developers and
customers.
What is the biggest misconception about your product or service?
Occasionally we meet a customer who thinks PCI Geomatics only
develops remote sensing solutions. Although PCI Geomatics has
a history of providing leading remote sensing software, this
is only one of the areas we serve. The geomatic sciences engage
disciplines beyond remote sensing, and so do we.
Our software development initiatives include products and services
that support remote sensing, GIS, photogrammetric, and cartographic
accomplishments within a single environment. Our geomatics solutions
provide a complete process: starting from raw imagery, performing
refinements, extracting information, and then presenting results
online, on a map, or exporting to a GIS database.
The advantages of combining the whole process in one environment
(versus multiple commercial applications) extend beyond real
cost savings. Interoperability efficiency, rapid file sharing
between sister applications, programming (a relative impossibility
across multiple products), design compatibility, higher performance
standards, and the avoidance of proprietary formats are just
a few PCI Geomatics’ advantages.

LASER MAP
L
Lasermap Image Plus has been a LiDAR service provider since
1997. With years of operational experience in a wide variety
of conditions—from the tropics to the Arctic, and deserts to
rain forests—Lasermap can guarantee clients a realistic cost
estimate with no surprises. The company has recently acquired
one of the latest Optech LiDAR sensors: an Optech 2050, one
of the most efficient LiDAR systems available. Lasermap also
has a digital frame camera, capable of capturing full color
imagery along with the LiDAR data. While the frame camera is
not necessarily suitable for very large area projects, it can
be efficient for smaller areas or corridor projects. Lasermap's
home base is located in the north east of North America, and
their work has taken them all over the continent as well as
to Africa, Asia, Central America, and South America.
If you could educate prospective customers about one thing before
they contact you, what would it be?
The best suggestion to clients contacting a LiDAR service contractor
is to provide us with as much information about their project
and project area as possible. This allows the estimator to make
a reliable financial estimate for the project. If some of the
information is not available, then the estimator has to make
assumptions which might not be correct. Clients looking for
LiDAR pricing should explain where their project is located,
as well as its approximate size and shape. (Shape can be very
important when designing flight lines—for example,”Northwest
of Dallas” is rather a large area!) Ideally, of course, the
client could indicate approximately how much of the area is
urban, farmland, or forest and, if possible, provide an estimate
of the overall change in elevation over the project area. It
also helps if the client knows of any ground control points
close by or in the project area. If the area is a corridor project
(compared to an area survey) then the number of changes of direction
is very significant. For example, many clients do not consider
that 100 miles of corridor mapping with twenty changes of direction
takes more than five times longer to survey than 100 miles of
corridor mapping in a straight line. (This is because it takes
several minutes for the aircraft to turn at each change of direction
and then align for the next segment.)
What is the biggest misconception about your product or service?
Possibly the biggest client misconception lies in scheduling.
LiDAR data can be provided very quickly, much more quickly than
most other technologies, and consequently clients come to expect
this. On the other hand, from a business point of view, the
service provider hopes that he is not just sitting on the ground
waiting for you to phone! While many projects can be completed
in a remarkably short time period, there are times of the year—such
as spring, when firms tend to be their busiest—when next day
service is usually not feasible. A bit of planning ahead can
ensure everyone remains happy.
Why might potential customers be apprehensive about buying
your product or service?
Some potential clients are apprehensive that LiDAR is “a relatively
new technology” and are not sure if they should “trust it.”
In reality, the concepts and individual technologies which make
up a LiDAR system are all well-developed and mature. Lasers,
inertial systems and even GPS have been around for years, and
LiDAR systems have become very robust over the last few
years. LiDAR systems today are as accurate as the components
they contain, which, with the off-the-shelf systems developed
by the major manufacturers, generally means (with attention
to proper operation and local control stations) accuracies of
six inches or better can be obtained in open, clear areas.

BENTLEY
Bentley, a global software vendor founded in 1984, provides
software solutions to create, manage, and publish architectural,
engineering, and construction (AEC) content. Bentley enables
leading AEC firms and owners to design, build, and operate facilities,
industrial plants, roadways, and other essential infrastructure
assets. Bentley delivers integrated building design, plant design,
civil engineering, and geospatial solutions for transportation,
process and discrete manufacturing, government and public works,
building, and utilities. Bentley’s 2002 revenues reached $230
million. Bentley software plays a mission-critical role in over
two-thirds of the work of the Engineering News-Record Top 500
Design Firms.
What type of problem/need does a typical customer bring to you?
Our users build and operate the world’s infrastructure: highways,
airports, industrial plants, utility networks, and buildings.
Our users require an integrated, multi-disciplinary solution
that helps them to design, build, and operate this infrastructure.
Yet, the common universal requirement is interoperability between
interdependent systems. Our AEC GIS Interoperability Initiative
with ESRI is the most compelling example of our commitment to
address this requirement.
While Bentley and ESRI applications manage data in a common
coordinate space, our respective applications are designed for
unique purposes and used by individuals with distinct organizational
functions. ESRI users are analysts and planners, while Bentley’s
are engineers and architects. The planning role requires a broad
view of spatial information, while engineers and architects
create detailed geometric drawings and models. Interoperability
will unify previously compartmentalized workflows. AEC work
will benefit from the spatial context that GIS can provide.
And planners will benefit from an updated record of constructed
infrastructure.
If you could educate prospective customers about one thing
BEFORE they contact you, what would it be?
It would be the value of a Managed Environment for AEC Content.
AEC Content comprises the design work of engineering disciplines,
architects, and mapping professionals, and includes vector files,
models, images, specifications, and more. AEC professionals
cannot operate without the context of what has been built. As
they extend and operate infrastructure, they rely upon the documents
of record. This information is the basis for everything new.
And effective management of such information is critical to
efficient operations.
A managed environment helps participants find information quickly,
share it, and make quick, effective decisions. Bentley believes
a managed environment requires three critical capabilities.
1) Change Management to determine who has access to what, and
when; 2) Intellectual Property Management to verify the author,
and track and seal changes; and 3) Information Query and Retrieval
to easily and efficiently locate content.
What’s the biggest misconception about your product or service?
The biggest misconception is the relationship between GIS and
AEC. A GIS is a self-contained, consistent, and rigidly defined
index of assets. The strength of GIS is the analytical capabilities
that such a paradigm enables. AEC work is conducted by a multitude
of collaborating players, typified by perpetual work in progress.
And AEC relies heavily upon document-based workflows.
In AEC, the map is not a navigational construct, but a highly
precise spatial setting, in 3 dimensions, for the scaled geometry
of physical infrastructure. It is large scale to reflect the
scope of this setting, yet must be very accurate at any given
point. A spatial context for AEC is critical and distinct from
GIS. While each leverages a spatial index, the information indexed
and the way that information is used is very different. Ironically,
however, a spatial index provides the appropriate medium to
support exchange of information and the foundation for AEC GIS
Interoperability.
