I've tried to dabble a bit with it, with mixed success.
There are too many data formats, and too little exaplanatory text for
identifying what they are, and not enough short, clear, concise documentation
for loading the data into software so it can be used.
It's all very confusing.
Apparently Christoph Hormann is a bit of a wizard with this stuff. Perhaps if
he still visits here, he could chime in with some advice.
I have GRASS GIS 7.0.4 and OSGeo4W, which I suppose is what I used to get the
heightfield data for the New River bridge WIP I did a while back.
