SRTM Tile Grabber

The SRTM Tile Grabber was originally developed as a web-based interface to simplify the process of downloading elevation data from the Shuttle Radar Topography Mission (SRTM). As of January 2021, the direct download functionality of this tool is no longer operational due to changes in external data paths. However, the interactive map remains valuable for users to identify the correct file names for desired SRTM tiles, which can then be downloaded from alternative sources such as CGIAR's website. This resource helps users navigate the SRTM data grid effectively.

Each tile provided information in GeoTIFF format at a 90-meter resolution, representing data from various web mirrors. The data linked through this interface corresponds to version 4.1 of the CIAT-CSI effort, which involved scrubbing, polishing, and gap-filling the raw SRTM data released by NASA. The site also recommends using open-source tools like GDAL for processing this elevation data, providing links to related resources and a GDAL cheat sheet for advanced applications.

Developed by @dwtkns using D3js, this interface aimed to make global topographic data more accessible. Users interested in browsing the original SRTM grid can also find a KMZ file for use in Google Earth. Any download policies of the respective data mirrors apply to the use of this data.
