Ground elevation map of the Amazon Basin (2000)
What it measures. A map of ground elevation across the Amazon Basin at about 1-kilometer detail, including the average height of each spot and a roughness measure showing how much the terrain varies.
How it's made. Drawn from the SRTM30 elevation model, which combined radar measurements made from the Space Shuttle in February 2000 with earlier survey data, resampled to this resolution.
How & where you'd use it. Useful for mapping terrain, modeling water flow and watersheds, and supporting ecological and land studies across the Amazon.

Official description
This dataset provides a subset of the SRTM30 Digital Elevation Model (DEM) elevation and standard deviation data for the Amazon Basin. SRTM30 is a near-global digital elevation model (DEM) comprising a combination of data from the Shuttle Radar Topography Mission (SRTM), flown in February, 2000, and the earlier U.S. Geological Survey's GTOPO30 data set. The SRTM30 resolution is 30 arc-sec or about 1 km. In processing the SRTM data, to combine with GTOPO30, the data were resampled from 3 arc-sec to 30 arc-sec. Provided here are the mean elevation and the standard deviation (STD) of the data points used in the averaging. The STD is thus an indication of topographic roughness useful in some applications.
