Hmapper is a useful converter from Grayscale GeoTIFFs to RGB GeoTIFFs.
It is extremely useful if you would like to distribute raster heightmaps using a WMS service, currently limited to 8 bits per channel.
Using Hmapper you are able to deliver a maximum height of about 167.7km (0xFFFFFF) with 1cm resolution.
If you need more resolution check out the next paragraph.
Height data is multiplied by OUT_FP_MULTIPLIER (100 by default) in order to deliver a better precision (centimeters).
This is hard coded right now so... fork me and make it an option :)
- libtiff
- libgeotiff
On OS X just do:
brew install libgeotiff
