If you don't find your favorite data format on this table, please check if it works and adapt the list above to share your findings. If it does not work, please open an issue. We will be happy to help you with the implementation.
Raster data can become quite big quickly, when working with uncompressed tiff files it's often several Gb of data. Especially on mobile devices, this is inefficient.
Usa il formato GeoPackage¶
We recommend to us the geopackage format to deal with raster data. The
following commands will convert a file called
raster.tif to a file
raster.gpkg with pyramids. Make sure you adjust
EPSG:21781 to your
