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.
