ESRI RETIRES ARCCAD AND ATLAS GIS
ESRI will end sales and support for two of its products: ArcCAD and Atlas
GIS. Atlas GIS sales ended March 31 and ArcCAD sales will end with April
30. Technical support will be available until the end of the year,
according to letters sent to users.
As I have a long history with these products, I can empathize with the
users of these products. I was a member of the ArcCAD team for many years.
I received my first live demo of Atlas GIS in 1990, then owned by
However, it is hard to argue that these products should be kept alive.
ArcCAD was originally built to work with AutoCAD 11, back in 1992. The
unprecedented collaboration of ESRI and Autodesk back then surprised many.
I spent many days as an ESRI employee in the Autodesk booth showing ArcCAD
and gathering feedback on where the product should go in the future. But
ESRI had a tough time keeping up with Autodesk�s fast pace -- as did many
other developers. ESRI survived AutoCAD�s move to Windows, the unlucky R13
and even AutoCAD Map, Autodesk�s competing entry into the CAD/GIS space.
However, after the launch of AutoCAD Map, Autodesk decided that ESRI was
no longer welcome in the Autodesk developer program. Even without
developer support or early access to new releases, I was pleased that ESRI
continued to support the existing user base for years.
But, let�s face it, CAD-based GIS --anyone�s CAD based GIS -- just
did/does not deliver on its promise. All of the attempts, from Dennis
Klein�s FMS/AC (gone), to Bill McKenzie�s Geo/SQL (still around, but
tiny), to Intergraph�s MGE (no longer in development), to ESRI�s ArcCAD,
to Autodesk�s AutoCAD Map/Land Development Desktop to Bentley�s
MicroStation Geographics (originally Mizar�s MicroGIS) were quite similar.
The integration between CAD and GIS was never complete �- you could never
just pick up the CAD tools and work on the data. Extra procedures created
entirely new workflows and made learning difficult. Try as they might,
splicing GIS genes into CAD package did not make graceful creatures.
To make matters worse, these products failed to deliver in the
Consider the best selling of these products, AutoCAD Map. According to
figures from their Autodesk GIS 2000 Conference, held last fall, users of
Autodesk mapping products are distributed as follow:
- over 600,000 AutoCAD-only GIS users
- over 150,000 AutoCAD Map and AutoCAD Land Development Desktop (LDD)users
- more than 17,000 Enterprise GIS users (Vision)
- 2000 Autodesk MapGuide installations with users measured in the millions
With the price difference of only a few hundred dollars between Map and
AutoCAD, Autodesk probably expected most of its GIS Users to switch to it.
Map probably did win some AutoCAD users over because it supports
MicroStation DGN files � something AutoCAD still does not do. More may
have had Map fall into their laps after buying Land Development Desktop
for engineering purposes. To me, this proves there just isn�t that much
demand in this niche. CAD based GIS did not, and does not, rule the world.
Look for other solutions to solve the CAD/GIS integration challenge
including Windows-based desktop GIS (GeoMedia, for example) and client
server solutions, like Autodesk�s own GIS Design Server.
Among the Windows-based desktop products was Atlas GIS. One of the early
products introduced by Strategic Mapping (SMI) in the late 1980s, this was
a fine piece of software. Simple, intuitive, inexpensive, Atlas was very
much the �Excel� of mapping. When SMI realized that selling inexpensive
software and expensive data was not working out well, they sold off their
data to Claritas and the software, Atlas GIS, to ESRI. ESRI more than
likely wanted the Atlas market share, which was mostly in business
geographics, a �hot� market in 1996. Indeed, ESRI did get a few hot Atlas
resellers with big accounts in the deal.
But the business geographics market on the desktop did not live up to
expectations and MapInfo ruled whatever there was of it into the mid �90s.
ESRI ended up with TWO Windows desktop GISs and had to simultaneously
market and support Atlas and ArcView, the rising star of the company. How
long could Atlas last? I feel strongly that it actually survived longer at
ESRI than it might have elsewhere.
Perhaps the most important thing to remember is that this is a business
decision, not an evaluation of the importance or quality of the products.
The fact that so many users did so much with the software products is
testament to their worthiness of the products and their role in the
industry. The work put into Atlas and ArcCAD continues to drive GIS
development and the data and maps developed in them will no doubt have a

MANIFOLD GIS CHOOSES ECW OVER MRSID
Earth Resource Mapping (ERM) recently issued a press release stating that
Manifold chose their ECW image compression format over LizardTech�s MrSid.
As there was no explanation of why, I got a hold of Dmitri Rotow, Manifold
product manager, who gave me the details. He explained that work occurred
during the time that LizardTech was involved with a lawsuit against ERM
for patent infringement, illegal use of MrSID trademarks, illegal copying
of a LizardTech SDK, making false statements when comparing ECW to MrSid.
�We actually did do a comparison between ERMapper and MrSid to consider
which SDK (if any) we would incorporate into 5.00 before we were aware of
the lawsuit. That analysis considered a variety of factors, including the
technology, the licensing terms and conditions of the SDK, the strategic
factors, etc. From our perspective as a software developer it was hands
down a choice for ERMapper.
�In a nutshell the key issues for us were:
1) Core technology. ECW really is supported by an open community that
exchanges many sophisticated ideas and actual code. Anybody (including
ERMapper and us) can't help but benefit from that. We could educate
ourselves in a deep and serious way on ECW using the resources of the open
community. We couldn't do that with MrSid. MrSID, in our view, was likely
to fall further behind with their approach.
2) Licensing. The ERMapper SDK makes it easy for a third party to
read/write ERMapper ECW formats. Their legal approach is surprisingly deft
and low key.
3) Strategic factors. We think compression is a good idea. ECW makes it
easy to add compression, as we've done in our own ECW implementation
(we're pretty good at math so this is no big deal given the open community
discussions about ECW). However, our business focus is not ECW nor are we
licensing our stuff to the entire world for free. ERMapper has a focus on
this and is doing a good job making it easy for third parties to use their
approach. It's a safe bet that ERMapper's SDK will become a widely-adopted
industry standard for interchange so we wanted to have it in 5.00 whether
or not we did our own. In contrast, it is difficult to see how MrSid will
become an interchange standard on the scale ERMapper's SDK makes
MAKING MONEY IN LOCATION-BASED SERVICES
To end-users location-based services sound like a good idea. People need
to find out where the closest drycleaner is. Many take this one step
further and believe people are willing to pay to get that information.
Questions: when we do pay and where does the money go? Or in other words,
who needs to be paid for the subscriber to get that information?
It�s actually fairly complicated. First, the carrier has to know where the
device is. Wireless carriers are currently scrambling to be sure they meet
the FCC deadline of October 1 to meet regulations in the US. Some are
�doing it themselves� and others are contracting with companies to provide
just the �locate me� piece. CellLoc, based in Canada, is a company
addressing just that part of the equation, though a sister company will
deliver services. CellLoc is building a network designed not to carry
phone traffic, but just to pinpoint locations of devices.
Once the device�s location is known, step two is mapping it and the
querying for the information of interest. There�s a bit of geocoding
(locating the latitude/longitude or the cell the device inhabits) and then
the GIS part: doing the spatial query and providing candidate �hits.�
Step three is delivering that response � in a map, or text or perhaps
voice. Now, it is entirely possible for three or more companies and
technologies to come together to answer the drycleaner query. So, what
happens to my $10 a month (I made that number up)? How much goes to each
piece? I suppose we�ll learn more about that as LBS comes online, but for
now, the GIS part is but a sliver of the whole.
PLAGIARISM ON THE RISE
A few incidents of content �borrowing� have left me less than comfortable.
Stung was our own site, TenLinks, one of our partner sites, and another
GIS specialty site. I cannot believe that the individuals were not aware
that they were in fact taking intellectual property of others and passing
it on as their own. Perhaps they thought they would not be found out.
A year ago, I uncovered a case of plagiarism. I had agreed to help a GIS
Masters degree candidate with her thesis. She interviewed me and I sent
her to several sites with white papers written by technologists at many of
the top GIS companies. When I saw her draft, I immediately recognized huge
passages taken verbatim without attribution. I told her that I�d have
nothing further to do with her education. Where I went to school, such
behavior resulting in expulsion, no questions asked.
But the writers involved in the recent website incidents were not students
but professionals. The Internet makes stealing even easier than in the
past, but it makes it no less unethical.
We at TenLinks do receive requests to republish our content and in most
cases, we comply, asking only that credit be given.
POINTS OF INTEREST
-A reader requested some details on the CeBIT Bluetooth failure. It turns
out the application was designed to give visitors to CeBIT indoor
map-based directions between booths. And, this detailed article suggests,
the failures were due not only to incompatibilities, but also overworked
servers and interference. On another note: Microsoft has decided against
in the box support for Bluetooth in its Windows XP due later this year.
- Palm and Sanyo Fashion House have introduced a new raincoat with a
special pocket for a Palm Pilot. Prices range from $185 to $695 at
specialty stores nationwide.
