Preparing the data

requirements: GDAL

NOTE: GDAL_NUM_THREADS=ALL_CPUS will use all the CPUs available, you can limit it specifing the actual number of CPUs to use GDAL_NUM_THREADS=5

COG

gdal_translate $DATASET $DATASET.cog -co NUM_THREADS=ALL_CPUS -co TILING_SCHEME=GoogleMapsCompatible -of COG

COG files must append the .cog extension to the original file name, this is not a standard, but the script expects this convention.

PMTiles

export GDAL_NUM_THREADS=ALL_CPUS
ogr2ogr -of PMTiles $DATASET.pmtiles $DATASET -dsco MAXZOOM=$MAXZOOM -dsco MINZOOM=$MINZOOM

PMTiles files must append the .pmtiles extension to the original file name, this is not a standard, but the script expects this convention.
