The automatic efficiency of traditional land use map generalization is very low and it needs the helps of human resources.The ArcGIS Desktop software provides the spatial data processing tools called Geo-processing.The tools could partially accomplish the assignment of map generalization.But they have not solved the generalization problems concerning processing sharp polygons and the inspections of minimum acute angle.This research is about how to generalize the sharp polygons and inspect minimum acute angle automatically.From the experimental results,the conclusion could be made that using ArcGIS Engine to generalize the sharp polygons and inspect acute angle could not only avoid the errors of manual operation and save the time,but also enhance the accuracy and reliability.The results showed that the methods proposed in this paper can get the best effect.
