These fields are used to uniquely identify the ''tile_data'' that should be Written or Read. GeoPackage Specification puts no restriction on how the tile_column or tile_data is being calculated for each tile. GDAL uses Block Offset and a Shift factor to write these fields. This creates a portability issue as other vendors might use a different strategy to write these fields. For instance, ESRI's raster2gpkg: [https://github.com/Esri/raster2gpkg] uses a linear algorithm to write the ''tile_row'' and ''tile_column'' fields." defect closed normal default unspecified normal invalid GeoPackage
