I need a georeferenced 3D model of a part of a city (1×1 km). The level of detail will focus on road elements like road markings, traffic signs/lights, bus stops, etc. Buildings are to be just massing models. I am thinking how PlaceMaker does it https://www.suplacemaker.com/placemaker/ .
I am looking for a SketchUp implementation, but if you can do it in CityEngine that works too.
Edit: to give you an idea, here is the area of interest
I would appreciate it if you can give an estimate completion time.
