DielmoOpenLidar is a GNU/GPL free and open source software based on gvSIG for managing LiDAR data. It allows to access, visualize and analize original LiDAR data, so the user is able to visualize a large amount of uncut LiDAR data (irregular points cloud in LAS and BIN format) together with other geographic data. In the future it also will allow to create basic products (DTM, DSM, intensity images, etc.) and final products with an added value.
