SRTM Digital Elevation Data Version 4

AI-generated Key Takeaways

• CGIAR/SRTM90_V4 provides global elevation data collected during the Shuttle Radar Topography Mission (SRTM).

• This version of the SRTM dataset has been processed to fill data voids for ease of use.

• The dataset has a spatial resolution of 90 meters and includes a single band representing elevation in meters.

• Users must acknowledge CIAT and adhere to non-commercial use restrictions; redistribution requires explicit permission.

• Earth Engine provides tools and resources for analyzing and visualizing the CGIAR/SRTM90_V4 dataset.

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.
