This is documented at http://gdal.org/drv_geopackage_raster.html . See APPEND_SUBDATASET=YES creation option, possibly combined with RASTER_TABLE. $ gdal_translate byte1.tif out.gpkg -of GPKG -co RASTER_TABLE=table1 Input file size is 20, 20 0...10...20...30...40...50...60...70...80...90...100 - done. $ gdal_translate byte2.tif out.gpkg -of GPKG -co APPEND_SUBDATASET=YES -co RASTER_TABLE=table2 Input file size is 20, 20 0...10...20...30...40...50...60...70...80...90...100 - done. > > Q2: If a geopackage has multiple Geopackage tile raster, If I wish to > convert any one to a geotiff how will I do ?
