“LiDAR or Light Detection and Ranging is an active remote sensing system that can be used to measure vegetation height across wide areas.
This [tutorial] page… introduce[s the] fundamental LiDAR (or lidar) concepts including:
• What LiDAR data are.
• The key attributes of LiDAR data.
• How LiDAR data are used to measure trees...”

“A Digital Elevation Model (DEM) is a digital cartographic dataset that represents a continuous topographic elevation surface through a series of cells. Each cell represents the elevation (Z) of a feature at its location (X and Y). Digital Elevation Models are a “bare earth” representation because they only contain information about the elevation of geological (ground) features, such as valleys, mountains, and landslides, to name a few. They do not include any elevation data concerning non-ground features, such as vegetation or buildings...”
