Edzer, I especially appreciate it is all S3 and can be heterogeneous under 'geometrycollection'. Tests, of course, are important and having fully fledged GEOS (though this may have to, eventually, cede to something like CGAL if the drive is additionally to 3+d). As to dimentionality (3d+) in GDAL-land, Frank and now Evan have been implementing variations for the past 10 years, even as 4dim gets expressed as 3dim, it doesn't error. So perhaps is is a function of post-processing after GDAL for achieving higher dimensionality for visualizatioin and other purposes. So now to become an adept at lists of sets of lists. Just wish I'd noticed this a little while ago.
