The points filter, which is made up of classification and return combination
values, determines the points to display within the LIDAR
Layer.
How to Modify the Points Filter
A display filter can be applied to points
as they are retrieved from the LAS
files. Applying a filter is useful for eliminating unnecessary points
such as when working with the bare earth or ground points. A filter
is the combination of the classification, return combination, and
elevation attributes for an LAS point.
Display filter tabs will display red
if a filter is in play. Also, all filter buttons should display "<<Source
Points>>..." when a point filter is actually set.
