On the subject of 3D topographic maps, you may want to contact the folks at Sandia Labs--Clint Atwood, Brian Pardo, and Darryl Reckaway. I have seen a scaled-down 3D topo of the Sandia Mountains, the major geographic landmark in Albuquerque, made in their SLS machine from USGS topographic data. As a native Albuquerque son, and as a lifelong map lover, I was very impressed. I think the raw data for raised relief map production is there for the taking/manipulating through USGS.

Subject: RE: Color
Our PRISM group at Ariz. St. just visited the Geography dept. on Friday to check out RP opportunities there. Creating 3D topographic maps with colorband satellite data overlay would create a miniature earth with cities, forests and furthermore, color-coded air pollution, popoulation, etc. I sense that the geograpy world has not fully grasped these possibilities, but I have only begun to think like a geographer and would appreciate any comments. Thanks.

Hi Ray,
again to quote my alter ego:
quote
When asked about color in models many engineers have stared back blankly,
"What would you need that for?"
"One of the most exciting possibilities of a full color model is in the
stress analysis field. Currently, after running a finite analysis,
a color plot of various cross sections are printed with the colors
showing the relative stresses in each area. Can you imagine the
clarity
that would result from being able to see the stress on the entire part
at once??!!!" Chad L Buchanan, Supervisor -RP and Model Shop at Cummins

Color is a quality of rapid prototyping that would complete it as a
mature communications tool. A fully colored model is both a picture and
an object and contains all the information of both.
"In manufacturing, color helps designers test working mechanical
assemblies," said Terry Wohlers of Wohlers Associates, Inc. "Envision
50
pieces assembled, all in a single color, versus the same pieces in
different colors," he explained. "What's more, RP models are used
frequently to propose new concepts and gain support from others when
developing new product ideas. Color is compelling and more accurately
communicates these ideas to others," Wohlers said.
