基于位置关系的地块矢量化成果检核算法研究

Research of Algorithms for Land Vectorization Check Based on Location Relation

矢量化已经成为GIS数据获取的一种中间手段,怎样提高矢量化成果的精度、对矢量化成果进行检核已成为研究的热点。提出了矢量化成果应满足的三个条件,对基于位置关系的地块矢量化成果检核算法进行了研究。

It has been an interim method to acquire GIS data by the scanning vectorization method, how to improve the precision of scanned vectorization pn）duction, how to check the scanned vectorization production, which have been the hotspots for research. It brings forward three terms which should be contented for the scanned vectorization production, and studies the algorithms for land scanning check based on location relation.
