[OSM-dev] reliefs follow up

[Artem Pavlenko]

Hello,

I had lots of fun generating reliefs today:) The utility can now read  
GIMP gradient files (*.ggr) :

./bin/darwin/debug/relief  --bbox=19,42,21,44 --z 4 --az=300 --alt=60  
-g ~/Desktop/DEM_poster.ggr ./srtm  relief.png

here are some shots:

All gradients are from http://sview01.wiredworkplace.net/pub/cpt-city/ 
index.html ( as suggested by Matt Perry)

Cheers
