摘要
地理信息系统中许多图形信息是通过已有图形数字化而来 ,这样不可避免地存在图幅间图元的接边问题 .本文利用 Object ARX在 Auto CAD环境下调试通过了两相邻图幅间的接边程序从而极大地提高了图形接边精度和作业效率 .
Many map data in Geographical Information System (GIS) are obtained by the figuration of previous maps, which produces the problems in border linking between the maps.The border linking program of the joined maps is designed under the platform of CAD using the ObjectARX, which accelerates the working process and enhances the map precision greatly
