Abstract
The polygon combination which includes aggregation and amalgamation is an important task in the generalization of thematic map.The spatial visual conflict of polygon groups which are lower than area thresholds is divided into four kinds and solved by different strategies.And a progressive combination method of adjacent polygon groups is mainly proposed,which can simplify the entire calculation progress,improve the computing efficiency,and make the changes reach the minimum before and after the generalization.
