fusionFUSION is a LIDAR data conversion, analysis, and display software suite. FUSION allows 3-dimensional terrain and canopy surface models and LIDAR data to be fused with more traditional 2-dimensional imagery (e.g., orthophotographs, topographic maps, satellite imagery, GIS shapefiles). FUSION processes raw LIDAR data into a number of vegetation metrics. Canopy- and ground-level surface models can be produced; and then, by simple differing, canopy height models can be generated. FUSION includes algorithms that allow the user to manually measure individual tree attributes or use automated capabilities to characterize individual tree attributes over large areas.
