No, the Geopackage BLOB is different from Spatialite. Have a look to the paragraph 2.1.3.1.1 in the Geopackage specification. > > If this is true (i cannot be sure now, hope wrong obviously) > this mean that will be another different format in a sqlite. > The Luciad libgpkg has a compatibility mode for Spaltialite 1.x,2.x and 3.x, which *should* guarantee read/write correctness for Spatialite layouts. Anyway, GDAL has its own implementation, and the gpkg driver is strictly directed to the Geopackage layout. > > The first is spatialite, the second is the porting of qgis to spatialite, > the third is this next coming version of geopackage on spatialite. > Yes, it will be a mess! :) When you will receive e sqlite DB what of the three forms will it be?
