So my posts fizzled a bit but I am continuing to model local buildings. About one every day or two even if they are a little rough. I figured I would start with the largest buildings in Marlton first and then branch outwards. I think it is easier to constrain oneself to an area so I decided that I would stay in Marlton/Evesham for a bit. Actually Evesham is the largest town in the largest county (Burlington) in New Jersey. What I am wondering now is whether I need to create lower level-of-detail (LOD) models for the same in order to improve the performance of GE when the models are turned on. Maybe some one in the GEarth community would care to answer.
