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.

栅格数据¶

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.

使用 GeoPackage 文件¶

We recommend to use 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
