MAPGIS制图过程中的误差分析与校正

Error Analysis and Rectification in MAPGIS Cartographic Process

利用MAPGIS实现地形图数字化是获取空间地理信息数据的主要手段之一,而图形数字化过程中会产生各种类型的误差。为此对MAPGIS图形数字化过程中产生误差的原因及减少误差、误差校正等问题进行了分析和探讨。

To implement topographic map digitalization by means of MAPGIS is one of main means of getting spatial geographic information data, and that digitalization could bring out diversified sorts of errors. The reason of producing error, the problems of reducing and emendation error are discussed.
