PROCESSED SRTM DATA

The data distributed here are in ARC GRID, ARC ASCII and Geotiff format, in decimal degrees and datum WGS84. They are derived from the USGS/NASA SRTM data.

CIAT have processed this data to provide seamless continuous topography surfaces. Areas with regions of no data in the original SRTM data have been

filled using interpolation methods described by Reuter et al. (2007).
