| Abstract: | The object-oriented image analysis method was applied to building roof mapping using IKONOS multi-spectral images combined with LiDAR data.The scheme to generate the building vector polygons includes the following steps:(1)image fusion and derivation of ancillary input data;(2)segmentation of processed data layers into image objects;(3)classification of image objects;(4)geometrical regularization of classified building object polygons.The experimental results show that object-oriented classification analysi... |
