I have Lidar data, ground points and first returns. I have processed it and have ready tiles from which I am trying to build 3D building models.
So far I was able to just extrude the buildings in the ArcScene and that is it.
I am a beginner in GIS/Remote Sensing and any help would be highly appreciated.
Also, I am trying to work this out in Arc10.

From my experience (also not a remote sensing expert), it's very hard to get accurate building outlines. If it is not a huge area, it might be worth manually tracing the buildings and then doing a spatial join with the LIDAR data to get the building heights.
