SRTM DEM data downloader in Whitebox GAT

A new great tool in Whitebox GAT

Whitebox Geospatial Analysis Tools

I just finished developing a tool for Whitebox GAT that will automatically download Shuttle Radar Topography Mission (SRTM) digital elevation models (DEMs) from the USGS SRTM FTP site. SRTM-3 data are among the best global elevation data, with a grid resolution of approximately 90 m. In many areas SRTM data provide the only topographic data set available. Within the United States, the SRTM-1 dataset provides an improved 30 m resolution. Not only does this Whitebox tool retrieve the SRTM tiles contained within the bounding box of a specified area of interest, but it will also import the tiles to Whitebox GAT, fill missing data holes (which are common with SRTM data in rugged terrain) and mosaic the tiles.

There have been many times in the past when I have needed to download numerous SRTM files, import the files, fill the missing data holes, and finally mosaic the…
