RE: [compass-users] Access to Digital Terrain Models to load to COMPASS?
Hi Larry,
Thanks very much for your usual very prompt and thorough help.
I successfully located and loaded a DEM from GeoCommunity. Unfortunately, the area of interest was right on the seam between two maps, but lo and behold, you already anticipated that and had a good fix available in your DEM Reader. I haven't been able to get to that work yet: I get an error message, I/O Error 103. Do you have a translation or recommendation for me to try? Both files will load and display successfully by themselves.
thanks!
Rich Aram

Rich,
I sent most of this information in a private email, but I thought some of the other cavers might benefit from these answers.
Thanks for your letter. I have updated the links on the Compass web page and rewritten a section that gives detailed information on how to download and use the DEM files. I would start by reading this section of the Compass web page:
I think you should be able to find all the DEM files you need for Lewis and Clark Caverns. If you have any problems the quadrangles, let me know which ones you need. They are usually specified by the same names used for the 7.5-minute topographic maps.
If you have any other questions, feel free to write.
Larry

I wish to load a Digital Terrain Model to our maps of Lewis and Clark Caverns in Montana. The link from COMPASS to the USGS site does not appear to work, so the USGS probably changed something. I plan to spend some time hunting it down, but I also hope other users can offer some suggestions and help if they have used it recently.
