Hi,

If you increase the -l <numOfLevels>  argument to 4, you'll at least preserve 
all the original heightmap points at the highest LOD tiles when you zoom in 
(albeit in a series of tiles). If you search for 64 instead of 63 you'll see 
where the default tile size is coming from.

If you just want a single terrain tile from your projected geotiff, then you 
could simply create an osgTerrain::TerrainTile using your projected image as a 
heightmap. You can ignore your NODATA values by setting a 
osgTerrain::NoDataValue in your TerrainTile's elevationlayer ValidDataOperator.

Cheers,

jamie
