Film p.t.: „Metoda fotogrametryczna i LIDAR w mapowaniu leśnym”
The photogrammetric method and LIDAR in forest mapping
The photogrammetric method consists of taking several photos of the same object, but from different sides. This results in a 3D model, or stereoscopic. Data obtained in this way provides much information concerning the studied object.
This method is not perfect. LIDAR offers much better results. Compared to the photogrammetric method, it makes it possible to reduce the number of flights over the studied object. It also creates an opportunity to filter out laser beam reflections, achieving separately e.g. a vegetation model, a landscape model, a model of rivers and their depth, etc.
The film presents both methods, but the LIDAR technology is more modern, providing incredibly detailed data about the surveyed area.
