Automatic Building Classification

So you have received LIDAR data and you really need to classify all those buildings in a timely fashion. The LP360 Planar Point Filter is an automatic process for classifying planar surfaces such as buildings.

Located in the Point Cloud Task tab of the Table of Contents window of LP360, you can quickly set up a custom filter for this process. (Figure 1)

Once you have your Point Cloud Task, in this example “Building Test Filter” created, there are several parameters that will need to be set. However, before you set those parameters there are a couple of things to be aware of. In order for the planar point filter to work correctly, the ground needs to be classified. Since the ground is largely a planar surface, it must be classified to remove those points from consideration.
