摘要
地图是GIS主要数据源 ,地图数字化是GIS数据输入的主要手段。分幅数字化常导致数据在接边处不匹配 ,地图接边是实现数字匹配的重要手段。文中详细阐述了MAPGIS地图数字化输入方法 ,通过MAPGIS图形变换功能 ,总结了 9幅分幅数字化地图拼接过程 ,通过MAPGIS图幅接边功能介绍了交互式、全自动。
A map is a chief source of GIS data. Map digitizing is a main means of GIS data inputting. Digitizing parting maps often lead to data not matching on edge matching. Map edge matching is an important method of digit matching. This paper describes in detail methods of map digitizing of MAPGIS,summarizes processes of piecing 9 parting maps together by using functions of graphic exchange of MAPGIS, and introduces interactive, automatic and semi automatic operations of sheets matching and realizing of digit matching by using functions of sheets matching of MAPGIS.
