Public Distribution



SRTM data for a number of sites within the United States are now available for download via File Transfer Protocol (ftp). Users should be aware that these data are intended for use with Geographic Information System (GIS) or other special application software, and are not directly viewable in a browser. Various types of visualizations (perspectives, stereo pairs, anaglyphs, etc.) generated using these data are available from the main page.

Also, users should be aware that the digital elevation maps and images are unedited and are intended for scientific use and evaluation. They are outputs directly from the SRTM interferometric radar processor, and for example may contain numerous voids (areas without data), water bodies may not appear flat, and coastlines may be ill-defined.

Data are available from the USGS server at ftp://e0dps01u.ecs.nasa.gov/srtm/

Be sure to read the ReadMe and other text files in the top directory at each site. They contain fairly complete documentation of the directory and file contents.
