دادههای شطرنجی¶
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.
استفاده از 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
desired CRS.
gdal_translate --config OGR_SQLITE_SYNCHRONOUS OFF -co APPEND_SUBDATASET=YES -co TILE_FORMAT=WEBP -a_srs EPSG:21781 -of GPKG raster.tif raster.gpkg
gdaladdo --config OGR_SQLITE_SYNCHRONOUS OFF -r AVERAGE raster.gpkg 2 4 8 16 32 64 128 256
