An example command for generating the GTA V map would be:
heightmap example_maps/gta5_fixed2_height.png -c example_maps/gta5_fixed2_color.png -s 4 -v 20 --tile -o gta5.brs
To use stacked heightmap for increased resolution, simply provide more input files. See the stacked_N.png files in the example_maps directory for example stacked heightmaps.
heightmap ./example_maps/stacked_1.png ./example_maps/stacked_2.png ./example_maps/stacked_3.png ./example_maps/stacked_4.png --tile
To generate HD heightmaps for the --hdmap flag, check out Kmschr's GeoTIFF2Heightmap tool.
