Abstract

The main characters of map generalization are analyzed in this paper. A new buildings' generalization method based on mathematical morphology is proposed to make the algorithm more effective: Firstly vector building objects are transformed into a binary image, in which vector objects are represented by raster features, the binary image is processed by means of morphological algorithms. Small bulged parts of houses are eroded by erosion calculation and small sunken parts of houses are filled by dilation calculation. Lastly the building's edges are extracted and transformed into vector polygons.
