Where can I find digital elevation data from SRTM?

The NASA Shuttle Radar Topographic Mission (SRTM) has provided digital elevation data (DEMs) for over 80% of the globe. This data is currently distributed free of charge by USGS and is available for download from the National Map Seamless Data Distribution System, or the USGS FTP site.

When was the first release of SRTM data?

The first release of Shuttle Radar Topography Mission (SRTM) data was provided in 1-degree digital elevation model (DEM) tiles from the USGS FTP server ( ftp://e0srp01u.ecs.nasa.gov/srtm/) in 2003. The data was released continent by continent, as and when the data was processed by NASA and the USGS.

Where can I find SRTM and X band data?

Research grade SRTM (C-band) data are available through NASA JPL. These data were sampled at 3 arc-seconds using a nearest neighbor resampling technique for global coverage. The German and Italian space agencies operated the X-band hardware and processed the data independently into a separate elevation data set.
