Download 30-Meter SRTM Data Easily With This Point and Click Interface

Derek Watkins has created a simple and easy to use interface for downloading 30-Meter SRTM data.  Arranged in tiles that are 1 degree latitude by 1 degree longitude, Shuttle Radar Topography Mission (SRTM) data was acquired over a 11-day mission in February 2000.  The mission collected elevation data from 56°S to 60°N and was the highest resolution topographical database at the time of acquisition (more: Mapping the Earth – the Shuttle Radar Topography Mission).

Downloading 30-meter SRTM from the Tile Downloader site is as simple as pointing and clicking.  The map interface is built with Mapbox GL JS as uses tiles from CartoDB.  Overlaid onto the baseman is the SRTM 30-meter index.  Simply pan and zoom (by double-clicking on the map) to the desired area.  Next click on a tile.  You can then either start downloading the data or you can preview an image of the DEM.   The SRTM data is packaged as a SRTMHGT files at 1-arc second resolution (3601 x 3601 pixels) and is pulled from NASA’s servers.

Visit: 30-meter SRTM from the Tile Downloader

Looking for 90-meter SRTM data?  Watkins also offers the SRTM Tile Grabber which links to GeoTIFF files created by CIAT-CSI. These files have been processed to fill data voids and there is a corresponding KMZ file which contains a 90-meter index for growing SRTM data.
