基于影像背景的关注设施专题图制作探讨

Discussion on Thematic Map Production of Concerned Facilities Based on Background Images

关注设施专题图是水利施工、灾害预防的重要参考资料。为减少制图工作量,解决该专题图制作周期长的问题,提出了应急保障时利用基于影像背景的关注设施专题图替代传统专题图的方法,并讨论了二者的差异,为不同时机采用不同类型的专题图提供了参考依据。

Thematic maps of concerned facilities can be of great value to hydraulic engineering and disaster prevention.In this paper,we proposed a new method to quickly produce concerned facility thematic maps based on background images for emergency security in order to reduce workload and shorten the drafting period.Then,we discussed differences between two methods.This study can provide a reference basis for using different types of thematic maps at different times.
