NASA Shuttle Radar Topography Mission (SRTM) Combined Image Data Set and Swath Image Data Release

March 04, 2015
By: LP DAAC

On February 25, 2015, two new NASA SRTM data sets were released by the LP DAAC.

The SRTM Swath Image Data (SRTMIMGR) consists of radar image files containing brightness values, as well as quality assurance (incidence angle) files for each of four overlapping sub-swaths that passes through a 1-degree-by-1-degree tile.

The SRTM Combined Image Data Set (SRTMIMGM) contains mosaicked 1-degree-by-1-degree images/tiles of uncalibrated radar brightness values at 1 arc-second. To create a smooth mosaic image, each pixel in an output is an average of all the image pixels for a location.

These new datasets can be accessed via DataPool and Reverb.
