RE: [emergency] Circle and Polygon

["Ham, Gary A" <hamg@BATTELLE.ORG>]

Actually, I remain pretty ambivalent in this argument for the moment.
The "excess taggage" approach actually helps to avoid the problems we
have experienced with some of Patti's more elaborate messages. It helps
to avoid huges string lengths that need individual parsing by allowing a
simple load into Java Vectors and the like.  The single string approach,
howver, is preferrer by my GIS programmers who, for some reason, find
string parsing preferable to significant attitional container
manipulation.

Len,

I cannot. Gary Ham has received complaints from DMIS users that the
messages that we post that contain large, complex polygons have caused
throughput problems. Gary, can you provide specifics?

Please, can you be more specific about the applications, 
the problem types, and where they occur (eg, 
on portable devices, desktops, etc.)?  Examples?

Message size has multiple solutions.

With the size and complexity of the polygons that represent
jurisdictional boundaries, I fear that the GML polygon representation
would become prohibitively large. Some applications are already having
problems ingesting the large messages containing the simplified version
for complex polygons.
