Lidar data is increasingly used in environmental sciences and natural resource management. Three-dimensional point cloud data, including both light detection and ranging, and Structure-from-Motion data, can be acquired from several different sensors. In this presentation, I will introduce how ground-based and airborne lidar data are obtained to estimate topographic surface height as well as vegetation height. The various lidar data sources have different levels of details and errors associated with them. These also lead to specific limitations and opportunities for the final products that can be derived from lidar data including DEM and vegetation canopy height models. I will introduce these concepts and their implications for the lidar data users.
