Commission VII, WG VII/4KEY WORDS: Cartography, Automatic Extraction, Photogrammetry, Aerial Photographs. Image Segmentation ABSTRACT:The objective of this research is automatic generation of buildings in the interest areas. This research was developed by using high resolution vertical aerial photographs and the LIDAR point cloud through radiometric and geometric digital processes. The research methodology usesknown building heights and various segmentation algorithms and spectral band combination. The overall effectiveness of the algorithm is 97.2% with the test data.
