Using Predefined Return Combination Filters

Predefined return combination filters are special groupings of commonly used return number and number of returns combinations. Many filters can be surrogates for what are likely points on the ground (Last of Many Returns) or in the canopy (First of Many Returns). Once a predefined filter has been selected from the list, the combinations may be customized to further define the desired set of points to return from the LAS files.
