Elevation - LiDAR (DP3.30024.001)

The elevation product, in the form of a DTM, provides information on terrain structure, and is an important data layer in spatially driven models of landscape processes. Currently, LIDAR sensors provide the most efficient means for collecting an accurate and dense sample of the terrain among competing remote sensing or positioning systems. For example, high-resolution digital stereo photogrammetry can compete in terms of point density in open terrain, but suffers from sparse sampling beneath tree canopy. The DSM provides information on the structure of surface features, including derived vegetation structure, which can be used as a proxy to estimate important ecological quantities of interest. Latency: AOP data will be available 60 days after the final collection day at a site.
