The Study On The Generalization Method Of City Settlements Based On The Attribution

With the development of GIS application and the expansion of GIS service field, the studying on auto-generalization theory and method of GIS spatial objects have became more and more important and be paid more attention recent years.In the past, researching on map generalization was almost based on geometry graphics, seldom considering the function of its attribution. In fact, attributions of the geometry graphics play an important role in map generalization, so studying on spatial objects generalization based on attribution of geometry graphics is very important and significant.On the basis of summarizing and analyzing the generalization model of native and aboard scholars, the author research on the spatial objects generalization based on attribution in the thesis. Including two problem, the first problem is how to generalize the attribute data after...
