--terrain switches the build to output osgTerrain::TerrainTile, that are base of height fields so the GDAL to OSG data structure is as staightforward a mapping as it is for imagery, this is far faster than tessellating a heigh field and then simplifying. osgTerrain database also can be simplified at runtime vai the osgTerrain::Terrain::setSampleRation(float). See the osgmultitexturecontrol example for this in action. This enables you to balance the geometry load with the capabilities of the hardware. osgTerrain is not finished yet, so further improvements will be on the fly boundary equalization and compressing the heightfields so the tiles on disk will be smaller.
