Hi all I have a large amount of DEM points from a laser scan, which cover part of an area where I need to create a surface model. When creating the model, I want to combine the points with contour lines and other elevation data. The laser data is much more accurate than the contour lines, and because of this, I want to use only the DEM points inside the coverage area of the laser scan.
In other words, I need to clip the contour lines (and some other data) against the coverage area of the laser scan. But my problem is that I don't have a polygon of the coverage area, I just have the points. Is there a simple way of creating this area? It's not rectangular, so I can't use a Bounding Box. I can create a small buffer around each point, and dissolve to one large area. But I think this would become a very heavy operation for my computer, given the number of points. Perhaps it would be better to create two surface models, and in some way run a overlay between them? Any suggestions?
