This question already has an answer here:

I am looking for an overview of file formats that can store geo-referenced 3D geometries. There are no further requirements such as texture support, etc.

I have found the following formats so far and seek extensions to that list:

  • Shapefile
  • GML
  • KML/KMZ
  • GeoJSON

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Do you have any other requirements? Because most GIS formats will support 3D data if you mean lat-lon-H or projected data with Z/elevation. I mean let's add Esri geodatabases, most RDBMS, DXF and DWG, etc. – mkennedy Jun 2 '14 at 18:44
  • I need a good and simple format to represent building geometries. Each building consists of a set of polygons. No further requirements. – Simon Fromme Jun 2 '14 at 19:05

    I wonder if you need to clarify further: I imagine there are (1) GIS formats that only allow 2D or 2.5D data -- no true 3D. (2) CAD formats that allow true 3D data but not geo-referenced. (3) True 3D GIS -- what you're asking about. And (4) Combo formats, like KML + DAE (Collada), that together provide what you ask for. Is that a useful classification? – Martin F Jun 4 '14 at 1:32
  • @AndreSilva I was just highlighting that this looks like a Shopping List Question. It is the reason why I voted to close it as too broad. – PolyGeo Jun 7 '14 at 5:14

If you are only talking about 3D geometry you can add the following:

  • PostGIS
  • Spatialite
  • SketchUp
  • OpenFlight

I create buildings in SketchUp, which can be exported to a number of different formats. If you load a georeferenced file, and building you make in SketchUp will inherent the georeferencing.

An equally important thing to consider is the means by which you want to view the building data.
