Moving Objects Workflow

For those of you that process mobile LIDAR data, it can be necessary to filter out the points that represent moving cars. This can be accomplished using the Classify Moving Objects routine. This tool classifies groups of points that are captured from moving objects. It can be used for mobile laser data sets. The routine requires…
