I'll post as well since I have some related questions.

The SDTS software for GRASS, which covers only the vector profile,
is at ftp://moon.cecer.army.mil/grass/incoming/SDTS*

Does anyone plan to write something for the raster profile? 

What is the future of SDTS? How is it progressing at ANSI?

I have heard that Australia is looking at it, but the EC has
DIGEST, France has EDIGEO, and Canada has SAIF.  What about ISO?
A month ago Kurt Buehler said that there was opposition to SDTS
at ISO---they want to start over and write another standard!

Does anyone have programming experience with SDTS? I have
been working with a trade organization that will likely adopt
SDTS. There has been some discussion of funding either 
 1. a simple tab, comma, or CSV value ASCII file to vector
    profile generator, or
 2. an OLE custom control, usable by any mapping package
    (produced by a member company), to write either a raster 
    or vector profile (for all entity types).
If there is anyone that is interested in this, drop me a line.
We would certainly want to utilize any available code (GRASS
or the Common Software Platform), but if SDTS will be dead in
three years, we may need to re-think the whole situation.
