摘　　要：图幅接合表既是正确标明测区各图幅相关位置的略图,又在生产管理中起到一定的作用。在实际工作中,其绘制和使用仍以人机交互为主,缺乏自动化机制。利用ArcMap中的dwg数据或线数据对要素复制、增密、分割、转点等地理处理函数进行流程化设计,利用ArcPy实现接合表图形的自动化绘制,并生成图号信息;再通过dwg图幅图名、图号定位方法自动检索图名,根据图号进行属性匹配,自动注记图名、图号;最后对生产过程中图幅不同阶段的信息进行分类管理和图幅接边状态管理,从而实现接合表绘制和辅助管理的自动化。Index diagram is not only a sketch map that correctly indicates the relative position of each map frame in the survey area,but also plays a certain role in production management.In actual work,its drawing and use are still carried out by human-computer interaction,lacking an automatic mechanism.In this paper,we used dwg data or line data in ArcMap for the process design of geographical processing function such as elements copying,densification,segmentation and turning points,used ArcPy to realize automatic drawing of index diagram graphics,and generated drawing number information at first.Then,we used dwg map name and map number positioning method to pick up the map name automatically,matched attribute information according to the map number,and annotated the map name and map number automatically.Finally,we classified managed the different stages information of map in the production process,and managed matching status,to realize the automation of index diagram drawing and auxiliary management.
