I'm not sure there's a point in defining a .shp2 spec. The GeoPackage one can be thought as the "new shapefile". It should have all its main advantages : - spatial index - random access - binary encoding of geometries Plus a few nice features : - attribute indexes - database format, with SQL capabilities - binary encoding of attributes - extensibility Its history is admitedly a bit young, but the specification is already standardized and has begun to be implemented in various software packages, including OGR. -- Geospatial professional services http://even.rouault.free.fr/services.html _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
