Seamless Shuttle Radar Topography Mission (SRTM) 3 Arc Second (90m)

Coordinate system: 4269 - "NAD83"


The SRTM tiles are DEM data divided in to one degree blocks for the surface of the earth. The data is divided into two resolutions, one at 3 arc seconds (90m) and one at 30 arc seconds (900m). 80% of the earths surface is covered for all of the area between 60 degrees N and 53 degrees S. SRTM data is in WGS84 datum and the elevation units are in metres. Digital Elevation Data for creating contours and other spatial analysis. World DEM data.These data are also available free of charge at
