TransDEM Forum

I've followed the instructions in the manual and in the tutorial here in the forum but I still can't seem to get the map georeferenced.

I have an image of a map from 1955, which I downloaded as a .pdf file from USGS, copied the image to the clipboard and then opened in TransDEM. However, whenever I try to enter the lat/lon (in this instance, SW corner is 31 deg 45 min/-106 deg 30 min), after entering the longitude, the latitude reverts to 0, no matter what I try.

I've tried this on two different computers, using XP and Win7, with the exact same result. I'm obviously not doing something correctly but I can't figure out exactly what. All the other program features work perfectly so I don't think it's the installation.

Anyone have an ideas or suggestions?

Thanks!

This is an example from Canada, but that shouldn't matter much.


TransDEM expects the longitude to be entered in the "East" field and the latitude in the "North" field. Could this be the problem?

Yes, that was the solution.

I'm not sure why I didn't see that but it worked like a charm. Thanks so much!
