The FetchSRTM tool finds and downloads SRTM and NED terrain data. The tool allows the user to batch download larger areas and saves and decompresses the data to a user defined location.
The tool can be downloaded at http://www.pathloss.net/fssetup.exe
You will require an Earthdata account to access the 1" SRTM data. You can register for an Earthdata account at https://urs.earthdata.nasa.gov/users/new
