摘要

土壤侵蚀宏观调查与制图

往往需要多个单位、利用多个图幅同时开展工作

图幅之间常常出现属性差异和界线位移的问题。GIS技术的出现

实现了图形形状的“无缝接边”

但属性差异仍然存在。针对这些问题

提出土壤侵蚀图接边的程序、原则和数字图的接边方法。为了提高工作效率

基于ARC/INFO软件的数字图接边

可以根据2个图幅和对应遥感影像的总数据量

选用单编辑层接边、编辑层和背景层切换接边、图幅分割后接边等3种方式。

Abstract

The macroscopical survey and mapping of soil erosion are generally carried out by many units that use many maps

thus there are some errors of attribute and position of polygons between these units and maps.The seamless joint of map comes true through GIS (Geographic Information System)

but GIS can not resolve attribute errors.The procedure

principal and the methods of vector map joint are put forward.For the high work efficiency

three methods based on GIS can be selected according to the size of maps and corresponding images

which are jointed in a single coverage reunited by two coverages

switch in the current and backg round coverages and joint the part/parts split form original map/maps.
