Abstract :
A simple classification scheme is proposed for LiDAR data from a mixed urban area. The basic classifications are urban, low, high, and other vegetation, and water. Standard deviation of elevation within a grid cell, point return number, number of returns per pulse, and point return intensity are used to classify each point individually. Additional classifications are based on the average elevation of the basic classes. The scheme classifies up to three-quarters of data points.
