LIDAR

Aerial lidar NOAA.gif
Light Detection and Ranging LIDAR is an optical remote sensing technology used to collect a wide range of topographic data. LIDAR is similar to radar technology, which uses radio waves, a form of electromagnetic radiation that is not in the visible spectrum. The range to an object is determined by measuring the time delay between transmission of a pulse and detection of the reflected signal. LIDAR technology has applications in Archaeology, Geography, Geology, Geomorphology, Seismology, remote sensing and many more areas. Light detection and ranging (LIDAR), also known as airborne laser scanning (ALS), is an emerging remote sensing technology with promising potential to assisting mapping, monitoring, and assessment of forest resources. Compared to traditional analog or digital passive optical remote sensing, LIDAR offers tangible advantages, including nearly perfect registration of spatially distributed data and the ability to penetrate the vertical profile of a forest canopy and quantify its structure. ... more
