RE: [compass-users] Access to Digital Terrain Models to load to COMPASS?
Rich,
The problem is probably caused by anomalies
in the files right at the edge between the two maps. For example, if the edge
of one map has 250 points and the edge of the adjacent map has 270, the program
has a problem trying to resolve the difference. (I have seen very strange data
in these files.)
Send me the two DEM files and I will look
at data and try to make changes in the DEM Reader that will handle the problem.
I have been successful at doing this in the past.
Please zip both files and send them to
this email address:
It has a large in-box and won’t
reject large files.

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,
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.

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.
