基于MAPGIS的地图扫描矢量化误差研究

On Vectorization Error of Scanned Map Based on MAPGIS

研究基于MAPGIS的地图扫描矢量化过程中所存在的误差:原始地图数据信息载体介质不同产生的误差、地图扫描与图像纠正中产生的误差、矢量化过程中产生的误差以及数据变更机制问题所产生的误差;分析了误差产生的原因。

This paper discusses vectorization error of scanned map based on MAPGIS, including error from dissimilarity of original map data carrier medium, error from map scanning and image correcting, error in the process of vector and error from problems of data change mechanism. The causes of errors are also analyzed.
