An area balance method for the cartographic generalization of the land utilization status quo database

摘要

In this paper, the feature selection rules of patches were regarded as the breakthrough point, based on data analysis and experiments, the computing method of area balance control of land types was put forward in order to solve the problem of area changes of every land type before and after synthesis. The computing method of area balance control of land types can be used not only to check up the rationality of rules before cartographic generalization, but also to provide assistance advice for revising feature selection rules according to the requirement of the synthesized results. It is helpful to enhance the rationality and reliability of synthetic rules, to achieve the area balance of various land types before and after it is synthesized, and to guarantee the quality of the diagram.
