基于Arcpy专题地图批量制作方法

摘要

To solve the problem of low efficiency and high repeatability in process of producing thematic map traditionally, the Arcpy site package of Python is used to improve the method of making thematic map.On the basis of the map template made beforehand, the thematic variable database is used.Arcpy is used to improve the method and consolidate links, such as citing thematic elements, rendering and symbolizing the thematic data, adjusting dynamically the content and layout of the elements of decorating map.A new technology of batch processing streamline production takes shape.Assessing the land ecology in Xinzheng is taken as the case.At the same time, the experiment application is conducted.The streamline operation is realized, with more automatic than ARCMAP, and less artificial intervention.%为解决传统的专题地图制作过程存在作业效率低、重复性高等问题,提出运用Python脚本语言中Arcpy站点包对专题图制作方法进行改进.在制作地图模板的基础上,引用专题变量库,并运用Arcpy对专题要素的引用、图层符号化与渲染、地图整饰要素的调整与修改、批量出图等环节进行整合与方法改进,形成批量处理的流程化制作新工艺.以新郑市土地生态评估专题图制作为例进行试验应用,实现流水化制图作业,该方法比ARCMAP更加自动化,更少人工干预.
