Abstract	Author presents a new hybrid method for LIDAR processing in the form of complex, real-world attribute-based 3D digital model of the terrain. This model can be widely used for 3D GIS analyses, visualization for public contracts, construction of new communications (roads), GPS navigation and generating individual views from any location. Model is based on the LIDAR scanned values that are transferred into the quadrilateral polygonal form. The main goal is to reconstruct large scale areas in 3D by slope based quadrilateral grids that are interpolated from irregular raw structure. Laser scan is checked and corrected. It is simplified by chosen interpolation technique into the quadrilateral set of grids (C++). Each grid has different resolution to lower hardware requirements. Raw scan is analysed by slope factor and is used further to classify grids into a groups. Classified grids are processed by 3D scripting language to form polygonal terrain model. Vector and polygonal data are converted into 3D and utilized to reconstruct surface features and terrain classes. Set operations are used to divide digital terrain model into the segments. Set of high polygonal models is created for each class. These models are scattered on the top of the classified polygonal surface.
