Ok, First off, my first post here. Now off with my dilemma, I am trying to get some DEM data for a couple of towns, but i cant locate any anywhere, and i was hoping you could help me. I am looking for two town both in the United States, and both in Massachusetts(MA) One is Littleton, MA and the other is Tyngsborough, MA. I am looking specifically for 30m level 24k. sorry for any mistakes, its late for me.
Locating DEM data

GIS Data Depot has always worked for me, although most quads are now 10m...
If you need to know which quads you need the USGS National Map Viewer has overlays.

The easiest way would be USGS Seamless Server: http://gisdata.usgs.gov/website/seamless/viewer.htm
G'day dnt462,
Littleton MA is located at Longitude 71.52298 degrees W and Latitude 42.54659 degrees N. TyngsBORO is located at Longitude 71.41172 degrees W and Latitude 42.69308 degrees N. Both of these locations will be found to 'reside' on the DEM tile N41W71 in the SRTM catalogue (which is 30 meter data), although I cannot recommend, highly enough, the 'quality' of the 1/3 arcsec (10 meter) resolution data available from the National Elevation Dataset (provided you are prepared to accept the necessary increase in 'memory capacity' required for it's use)...

"...Well, I spent most of yesterday looking for this, and i can tell you, its not at GIS Data Depot, and i cant find anything that makes sense to me at the other link..."
...which I find most intriguing as I have just NOW found both locations (quite easily), directly from the link supplied by geophiil, above...
