Attendance seemed to be good-I heard numbers in the thousands for each day's total registrants. I confess that I did not attend a single session, so I can't speak to
how papers were received. I will say that exhibitors seem to have made great strides in tightening up their demonstrations. Not once did I find myself stuck in a
long, dull, feature function inventory.
I visited with Visual Learning Systems (more below) and when I let them know I only had 15 minutes to listen, heard the company's "elevator pitch"-a one-sentence
statement of what the product was and how it fit within the market-and got a quick demo. Kodak's Research Systems Inc. took another tactic: they used the theory
that the best demo is one you never give. Despite my suggestions that I'd like to see an example of how the company's ENVI software works, I never got the
chance.
Finally, I'll note that as much as things change, they stay the same. Time spent at the National Atlas booth revealed that every visitor to a mapping booth basically
has the same ultimate goal: to see his or her house or region. The big difference between that demand, which I heard regularly ten years ago (when I started
demoing), and today, reflects exhibitors' ability to comply. Today, most vendors CAN show a house (or at least a region of interest) from local or distant servers.
Unfortunately, doing so rarely shows off the specific solution the vendor is trying to highlight, but rather shows the data sets available.
ENVI, from Research Systems Inc. (RSI) is one of those products you hear about, but not so much as others in the image analysis space. Now, after the purchase
by Kodak, RSI hopes to find new users in the many traditional Kodak customers of film and aerial cameras. That said, ENVI already has some 200,000 users
across its many clients, including NIMA, FEMA and USGS. The software is aimed at hyperspectral and multispectral imagery processing. It has tools to process
just the area of interest (or as they call it, ROI, region of interest) and based on the signature of one pixel, pull up a likely candidate for the material from a library.
RSI is excited about a new service, EON (ENVI Online), that allows an organization to host a trimmed-down version of the software online along with the typically
large imagery files. EON is currently in use by NASA Goddard, which hosts a system for Maryland schools to use as part of their remote sensing curriculum.
Kodak is still a film company and there are new films available. Kodak also offers a new service to scan and host existing film archives for distribution via the Web.
Kodak is trying to redefine the imaging industry with a new term: infoimaging. The company even put a colorful advertising insert in the Wall Street Journal to define
the term as the convergence of information and images. It's still not clear how widely used this term is. A quick search shows the term still only used by Kodak, its
subsidiaries and partners. Time will tell if this term sticks.
In addition to the list of acronyms I learned at the Kodak booth, I found the show floor brimming with even more! The four-letter acronym, DIME, explains the
goal of Positive Systems software: Digital Images Made Easy. The software sits between data acquisition and image analysis and does three things: mosaicking,
color balancing and georeferencing. With 14 employees, the company's business model is particularly interesting: the software runs under $1000 but credits for use
are $5. So, it's sort of a pay and you go model or what VP Dale Johnson calls "the cell phone" model. The company's literature describes the investment in terms of
a car purchase: first you buy the car, then you regularly pay for gas. DIME user organizations get as many copies of DIME as they like and use their credits
wherever and whenever they like. The model works well for contractors who bid on imaging and for local governments who can easily budget software costs for
the year ahead.
It took a moment to figure out which company's employees were wandering around in black shirts and blue and black ties. It was Leica doing a bit of a "Men in
Black" look. I visited with Cyra, one of the company's recent acquisitions, and got a first-hand look at the 3D data capture instrument. What I didn't quite
understand until now was that the solution is basically LIDAR. A laser pans across the view and paints a 3D dot cloud into a digital file. This sort of LIDAR is at
the other end of the spectrum from that used from airplanes. In contrast to aerial LIDAR, Cyra's instrument moves slowly across the scene and must be fairly
"close" to the target.
Unlike the aerial LIDAR solutions, the Cyra system doesn't have an integrated GPS system. An external GPS can easily be used to locate specific points in the
scene and interpolate location information. And, just to be sure the crew back at the office knows what the 3D image looks like in "real life," a digital photo is
captured at the time of the scan. The data cloud can then be brought into a design package and used as a backdrop for changes or additions.
Telemorphic's Maplicity is the technology behind websites dedicated to publishing maps of the David Rumsey collection online. The company's Java solution for
ArcIMS puts a host of powerful GIS tools in the hands of a user with a browser. My favorites include the ability to easily create and then intersect a buffered road
with underlying data and various tools to examine imagery by changing translucency. Telemorphic is looking forward to a new version, which should include even
more imagery tools and a more robust software development kit (SDK).
Also on the horizon is Maplicity Enterprise, a tool to share data created with the browser tools with other users by hosting it on the server. This product, which
adds onto the core functionality, solves the problem of how to easily add vector data to a server for group access. Down the road Telemporphic wants to move
exclusively into the toolkit business. One way to think of the Maplicity SDK, at this point, is as a junior version of ESRI's MapObjects Java.
Intergraph was showing a variety of products, but most discussion seems to turn to GeoMedia Web Map. The new version (5.0) is expected in July and boasts a
Java client which is smaller, lighter, and more secure than previous plug-ins or controls for CGM. CGM is the vector delivery format for Web Map. The new
version will also include support for the OpenGIS Web Map Server specification, allowing data from GeoMedia Web Map servers to be integrated with data from
others servers implementing the specification.
Visual Learning Systems product Feature Analyst won the Most Innovative Solution Award at the recent ESRI Business Partner conference. So, is it innovative?
The answer is an unqualified yes. Feature Analyst is very "smart" feature extraction tool that sits on top of ArcView 3.2 or 8.1. It finds features in any type of
ArcView-supported image, and creates shape files to illustrate them. The process of "teaching" the system about the target feature involves digitized a sample area,
then setting other parameters-such as describing it as vegetation or pavement-that help the system tease out the properties of signature. There are tools to let the
system know how far from the object to look for context. The reps highlighted the accuracy of the system and I have to say the trees we sought from a 6"
resolution aerial photograph had the odd shaped crowns that scream "natural." Further, by teaching the system with care, including pointing out errors, it's able to
distinguish between sidewalk and road, where other systems only see pavement.
On Wednesday, I attended the Management Association for Private Photogrammetric Surveyors (MAPPS) breakfast. The speaker was Scott Cameron, Deputy
Assistant Secretary of Interior who positioned Geospatial One-Stop (GSO), one of the 25 e-government initiatives in the President's management agenda. The goal
of all of these is to provide a "quantum leap in value" for the public. GSO is the next step in Clinton's NSDI, but this time the goal is to look at and encourage
external input. NSDI, Cameron suggested, had more of an introspective vision. The main concepts for GSO are simplification and unification. In terms of
simplification, for example, he pointed out that if potential players in GSO don't follow standards, it's an indication that perhaps we are offering the wrong
standards. Unification refers to interoperability.
One of the more interesting things Cameron suggested was that USGS consider not "filling in" all the holes in national coverage in certain products. Instead, he
argued, it may make more sense to work the localities to provide data that is useful. For example, maybe it makes little sense to cover New York City at 1:25,000,
but coverage at 1:4,000 would be welcome.
When asked about how to "follow" Geospatial One-Stop progress, Cameron noted that representatives from various agencies would be selected in the next week
or so and that they could provide insight. He also said the federal geodata acquisition plans should be finalized in late spring or summer. Local governments are
encouraged to post theirs, too, to create a marketplace of demand.
Cameron also highlighted the government's initiative to support competitive outsourcing. The idea is to use the competitive model of the private sector for
government work. The goal is to have 15% of jobs selected this way in '03 and then head toward 50% in coming years.
