USGS Geographic Data Download
Software sites are provided for your information only. Direct questions to the originating Web site. The USGS does not support software on non-USGS sites.
Make sure to read the README files under the account in which the software resides before downloading the programs. Sometimes the servers we point to have exceeded the number of allowable users. If you get an error message when you click on a link, try it again at a later time.
Note: The LULC and Native format DEM and DLG data do not contain record delimiters. Some commercial software requires that delimiters be added. In some cases, you will need to add delimiters before using display programs. USGS Windows 95 viewing software (DLGV32) will display the data correctly with or without record delimiters. SDTS formatted data does not require delimiters.
Public Domain Software for SDTS
USGS DEM to TGA converter-- dem2tga4 is a public domain program that will convert 1:250,000 scale (DEM) data and create a TGA (Targa Image) file from it, which is viewable from most graphics viewers and applications.
