Create a MBTile from a GDAL VRT. (Creating a VRT)
gdal2mbt create goteborg.mbtiles 8 goteborg.vrt
Or use a JSON config file with an optional metadata dictionary that will overwrite the defaults in the MBTiles metadata table.
{
"source": "goteborg.vrt",
"num_levels": 8,
"metadata": {
"name": "goteborg",
"description": "Aerial photos over Göteborg city"
}
}
gdal2mbt create -c goteborg.json goteborg.mbtiles
To resume an aborted MBTiles creation process pass the -r
flag to create
.
Speed up MBTiles creation by distributing the load over several processors or even computers by using GNU Parallel.
Create an MBTiles file for each tile on zoom level 0, this will depend on the second argument which defines how many zoom levels to generate in total.
gdal2mbt config goteborg.vrt 6 | parallel gdal2mbt create -c
Merge all the created MBTiles to one.
gdal2mbt merge goteborg.mbtiles goteborg.*.mbtiles
Or to squash all MBTiles into one to save space use the destructive -s
flag
which will remove each merged MBTiles file.
gdal2mbt merge -s goteborg.*.mbtiles
Add zoom levels that might have been omitted due to the amount of tiles on zoom level 0 at time of creation.
gdal2mbt levels goteborg.mbtiles 8
