Hi Robert and Umit, As probably you already read it, my data is georeferenced but has no projection info (plain latitude, l,ongitude). Using plain osgdem produces a wrong 1 dimension field (a line).
osgdem -d volcanes.tif -l 8 -v 1.0 -o kk I have to give some approximated --xx and --yy data to make it work and even so it does wrongly, creating the mirror image in the Y direction, as you can see comparing the texture image with the produced terrain. Any hint? Where can I find documentation about vpbmaster, vpbcache and vpbsize? Regards, -- A.
