This concept caught my attention. The European Science Foundation ESF is sponsoring an exploratory workshop to bring together researchers in the GIS and laser scanning fields. This is a first to my knowledge. The conference will take place September 8 -11 in Heidelberg, Germany.
The preliminary program and list of participants it is not open to the public will be published soon. It would certainly have to include discussions of LiDAR mapping and I would assume 3D cities. In any case it is an interesting combination and I have to believe an approach that we should be discussing around the world.
The GIS community knows a lot about managing large volumes of geospatial data, but not about laser scanning. This makes a lot of sense.
