SRTM Digital Elevation Data Version 4

  • The CGIAR/SRTM90_V4 dataset provides consistent, high-quality digital elevation data from the Shuttle Radar Topography Mission, processed to fill voids and enhance usability.

  • This dataset, available for the period of February 11-22, 2000, includes an 'elevation' band in meters with a 90-meter pixel size.

  • Users are prohibited from commercial resale or redistribution without explicit permission from CIAT and should acknowledge CIAT as the source in any resulting work.

  • The dataset is available for analysis and visualization on the Google Earth Engine platform, free for research, education, and nonprofit use.

Description

The Shuttle Radar Topography Mission (SRTM) digital elevation dataset was originally produced to provide consistent, high-quality elevation data at near global scope. This version of the SRTM digital elevation data has been processed to fill data voids, and to facilitate its ease of use.
