Provide means to edit CityGML files

[jailln]

We need to edit the geometry of CityGML files. First, we need to check if a CityGML editor already exists. If not, we could go this way:

Using 3DUSE

• Open the CityGML file in 3DUSE
• Select the CityObject to export (either in treeview or in the 3D scene)
• Export the selected object either to a .obj using 3DUSE's CityGML -> obj converter

Using 3DCityDB

• Load CityGML file in a 3DCityDB database
• Export it into a collada file

Then, the collada / obj file can be loaded in a 3D editor such as Blender or Maya for modification and exported to an obj file.

Once the modification is done, refer to this issue to go from obj to CityGML.
