python3 terrainmaker.py -o ./terrain_tiles dem.tif

Usage: python3 terrainmaker.py [options] GDAL_DATASOURCE
Options:
    -v, --version           output program version
        -h, --help              output help information
        -l, --fill <raster>     fill nodata by another raster
        -o, --out_dir <dir>     output directory for terrains
        -f, --format <format>   terrain format: heightmap/mesh, default is heightmap
        -e, --max_error <float> maximum triangulation error (float [=0.001])
        -m, --mode <mode>       output storage mode: compact/single, default is single

Recommendations

  • Input GDAL_DATASOURCE elevation data should have only one band or elevation band is the first band.
  • Input GDAL_DATASOURCE band must create overviews if band's X-Size or Y-Size greater than 2000 pixel.
