Does one of the FDO providers support height map files? Either:
ASC - ASCII Arc Grid
DEM - Digital Elevation Model
SRTM - Shuttle Radar Topography Mission
If not I'd like to get started writing one. What I need is a raster provider that will produce a hillshade. I already made the code to produce images of ASC files, and if no such provider exists I'd like to get some information how to get started producing a provider with these capabilities.
I imagine something like the gdal provider where you point to the file or to a directory containing multiple files and that a raster layer can then be rendered using the files. Here is a sample output from my code:
There could be options to produce greyscale or colored (as the sample), or to use hillshade/shadows or not and other options.
