Citygml

I think it would be a fantastic feature to add support to export Citygml files for use with projects like 3dcitydb !

A CityGML export is occasionally requested as a feature, and it would be good to have as one of the Targets in OSM2World. Wishlisting it.

Here's my use-case (https://github.com/stirringhalo/osm2citygml). Osm2citygml is similar to https://github.com/stirringhalo/osm2cesium but will be much more scalable with 3DCityDB backing.

CityGML is a feature I'd love, even with just GenericCityObject as opposed to fancy semantics. It saves an FME license, processing time and data handling.

I pinged the folks at 3dcitydb / citygml4j if they like to help you on adding that feature:
3dcitydb/importer-exporter#81

[Matthias84]

They are ready to help to add export using https://github.com/citygml4j/citygml4j
Can anybody support form the O2W side?

Using citygml4j looks like a very promising building block for a OSM -> CityGML pipeline. The main challenge would appear to be mapping OSM2World's internal representation onto citygml4j's, but it seems feasible at first glance. I'm interested in exploring this further and would be available for a meeting as alluded to in @clausnagel's most recent post.
