Airborne Remote Sensing intensity of the laser return can provide a proxy for soil moisture and other surface characteristics beyond the topography that is expressed as x, y, David C. Various methods have advantages and disadvantages and the specific method used depends upon the scale of the area under study, financial means, desired measurement accuracy, and additional variables. Airborne laser scanning (ALS) was used to obtain high spatial resolution data of the 3D canopy structure. The data has been utilised to build a canopy height model and provides valuable information about the foliage density. In 2012, extensive archaeological ruins were identified deep under the canopy of the Honduras Mosquitia through the use of airborne Lidar survey, conducted by the National Center for Airborne Laser Mapping (Ncalm) out of the University of… High-resolution bathymetric surveys support aquaculture research in Canada and increase navigational safety in the Pacific Ocean

This paper investigated the potential of multispectral airborne laser scanning (ALS) data for individual tree detection and tree species classification. The aim was to develop a single-sensorsolution for forest mapping that is capable of…
Both structural and spectral variables from photogrammetric data were used as predictor variables. Furthermore, when available, accuracy figures from ALS based inventory were used as a benchmark.
