Refinement of heightmap and textures: ------------------------------------- The heightmap and colormap (textures) are refined to produce a more realistic appearance and to correct visual blemishes.

• Seam between land and water: Random offsets are suppressed at the land/water seam. Otherwise, land above water level may be painted blue. A sandy color is applied at the same.
• Water texture: In the colormap, heights below the watermark are assigned a synthetic RGBA by accessing texels in a water texture. This is done in C++ (water texture isn't rendered).

#define IF_RANDOM_LAT_LON

Value:

if ( EX( (lat > 0)                                      \
          && (lon > 0)                                      \
          && (lat < msHeightmapWidthMinus1)                 \
          && (lon < msHeightmapWidthMinus1) ) )
