摘要
地图数字化是地理信息系统工作的首要任务之一,针对地理信息系统地图数字化过程中常见的多图幅数字地图逻辑拼接以及数字化后易出现的空间逻辑错误问题,提出一种基于ArcGIS的数字地图逻辑拼接和空间逻辑错误检查方法,实现了真正意义上的多图幅数字地图逻辑拼接,并在河南省航道基础地理信息管理系统中应用,取得了理想效果.
Map digitization is one of the first job of the GIS work. aim for the usually question of logical join of multi - sheet maps and then the logical wrong in this first job, The authors discuss a method of logical join of a multi -sheet digital maps and can correct the space logical wrong based on the ArcGIS , and realize the multi - sheet digital maps logical join in a real meaning, then applied in the practical of the inland river channel GIS of HeNan province ,and get an ideal effect .
