Canopy Height Models (CHM) are how many of us perceive LiDAR data and outputs in GIS systems in 2D, but sometimes it is good to understand how they actually represent the underlying LiDAR point cloud data. A client recently asked about the difference in height between...

One of the common questions we are asked is how many pulses per square meter (pulses/m2) should be prescribed in a LiDAR survey to result in a “good” digital terrain model (DTM / DEM). The question then becomes what density of vegetation is covering the...
