Abstract: The resulted data handing and database construction of the second land resource survey includes the land-use data generalization and map design of different administrative levels.From the perspective of practical works,we explore a technical method of land-use data generalization,including the detection of polygons with closest relationship from neighborhood candidates,the establishment of the generalization rules,the aggregation and amalgamation methods for polygon combination and the evaluation of the generalization results.
