Here in Pennsylvania we have a wealth of free lidar data I would like to use in some of our planning projects. I have no problem loading the data, however, when everything is loaded there seem to be "stray" points floating high above the surface. When I try to build a grid or tin they create these tall spikes. First off, what are these? Second, how can I filter them out? I have attached a 3d view of the points loaded, they are hard to see but are the red dots floating in mid air. Any help is appreciated.
