Is only GeoPackage an open, platform-independent and standards-based data for GIS that is supported by an standard organization ? Or are there other formats/data schema?
Like how for BIM there exist the IFC that is platform-neutral, open data schema specification developed by buildingSMART. Even an official International Standard ISO!
I know there also exist dotbim, however it has no organization behind it.
GeoPackage is developed by Open Geospatial Consortium.
Does even an official International Standard ISO exist for GIS?
