Other SDTS Sources

This page (click on 1:24K DEM graphic)

http://edc.usgs.gov/geodata/

lists 2 other sources for free SDTS files, both of which are faster than gisdatadepot. The mapmart was 560 kBps, atdi 17 kBps. The mapmart is limited to 10 files per order, but it appears easy to place additional "orders".

There are other sources for DEM info, but would require coding for different file format.

If any fellow Texans read this, the Texas Natural Resource Information Service (TNRIS) makes 30m DEM data available on their web site, in old DEM format (non-SDTS). Their interface is also very easy to use: http://www.tnris.state.tx.us/digital.htm

I've just started looking for similar organizations in other states; post up others here.

(I originally said 10m.  It's really 30m.)

Thanks to Tom Harvey for the following link to tons of DEMs for states west of Kansas or thereabouts:

This site, http://130.166.124.2/dems.html, has most of California in DEMs, with clickable map, nice and quick to load. The other states are in SDTS just with quad names, which is more demanding. I worked on some parts of Utah by getting quad names from http://nrwrt1.nr.state.ut.us/cgi-bin/quadview.exe and then downloading one by one from the above SDTS site.

I'd like to suggest some kind of sharing scheme between the people here, since getting the DEMs is painful (although a bit less with Alan's program).

I have most of Wasatch Front and SW Utah (St. George, Gooseberry) now, which I can compress and put on my website, if there's interest. I'll probably end up doing most of Utah, at least the places where I've been. Don't want to advertise this too much, as it's an university site, but, a few dozens downloads would be OK.

Pls, let me know if others feel like joining in.
