地形图整体接边技术的探讨

Study on the Technology of Global Edge Match for Topographic Maps

在传统生产实践中，地形图接边的方式为逐幅修改，但这种方式的效率非常低下，修改也很难彻底。为此，应该设计一个适宜的技术方案，以实现地形图图元与图号的自动匹配，实现多幅地形图合并后的同步修改、自动分割、自动输出，从而实现地形图的整体接边。

In the traditional production practice, edge match of topographic map is modied one by one, but this approach is very inefficient, and it is difficult to be completely modified. Therefore, we have to design an appropriate technical solution to achieve automatic matching topographic maps element and code, to achieve synchrous modification, automatic segmentation and auto-matic output after multiple topographic maps combined, thereby to achieve global edge match of topographic maps.
