Semi-automated building extraction from airbone laser scanning data on the example of the central campus of Wasaw University of Technology.

The main idea of this project is to introduce a conception of method of semi-automated building extraction from Airborne Laser Scanning data. The effects will be presented on the example of the Central Campus of Warsaw University of Technology.
Airborne LIDAR has become a very popular technique for acquisition of terrain elevation models and lately, also of covering the area. Creating studies based on LIDAR data is more and more universal solution in commercial, marketing, scientific, architectural and engineering fields. Due to the high density of acquired points and increasing received accuracy, this method is very useful in generation of three-dimensional models of cities, regions or individual objects of the highest level of detail possible to achieve.
The main goal of realized project was to find the most effective algorithm of automatic acquiring planes for roofs. Effects of this algorithm were proceeded in software such as ArcGIS, SketchUP to generate roofs and finally to make complete building models. Based on partly semi-automatic and partly manual method, can provide models at the level of detail LoD 2 CityGML standard.
