Totally new to this product (installed today). Have loaded a sample set of LAS files, things look fine. Two quick questions: 1) Tried to show points, by classification. When ENVI-LiDAR displays the classification already in the LAS files (which appear to be very good to me), I get a gray-scale display. Is there any way to control the colorization of the existing point classifications in the source LAS files? 2) Ran the automated processing, and got ENVI-LiDAR to pick out some of the features from the point cloud (i.e., it does its own new classification). It did okay, but did miss quite a few buildings. I imagine I can tweak some parameters to do better; but, is there a way I can tell ENVI-LiDAR to use the existing classification, instead of generating a new one? The goal would be building footprints (vector shapefiles) from points already classified as buildings in the LAS files. Thanks, -Bruce
