SRTM Height Map Converter

This is a small tool to get (16-Bit PNG) images from the height map data generated from the satellite radar data of NASA and others.

Details about the data can be found here and the data itself (segmented by a 1° world grid) can be downloaded here.

Example usage

To try it out, just try this:

make # build it
./pkg/height-map/testdata/download.sh 48 10 # download some test data
./build/convert-hgt -in N48E010.hgt -out test.png -auto-improve # convert it

This will give you this nice picture of the Ulm region:
