I see - thanks for the parallel. > Ah, that's complex features, the old GML driver would have supported > simple features only anyways. > I believe that could be mapped onto a large set of database tables, but also > that you have to write your own conversion software and "application > schema" mapping files. That's a large amount of work I fear. suppose I get as far as converting AIXM content into a PostGIS database. how would I go on from there? I'd add a PostGIS data source to GeoServer, and use SLD for stlying bitmaps? but how would I add more advanced filter handling, so that one can query for data using AIXM-specific features (say, query for navaids, or airspaces, etc.)? How would I make the GeoServer's WFS protocol handler return AIXM? I guess I'd have to write PostGIS -> AIXM mapping code for that purpose..
