About the Source Filter

The source filter defines the set of points that are used to locate planes in the point cloud data. A typical set of points used in the planar filter would exclude point classes that are defined as ground points, or any other class that has already been classified, such as vegetation. Any point on a class included in the source filter can be classified to the destination class. Therefore, exclude all points (i.e., classes) you wish not to be classified to the destination class. In general, the more points that can be excluded from consideration will produce more performance and better results. The source filter is modified using the display filter property page.
