基于ArcPy与数据驱动页面的专题地图批量制图方法研究

Research on Thematic Map Batch Mapping Method Based on ArcPy and Data Driven Pages

针对自定义分幅专题地图无法批量输出的问题,提出了一种全新的专题地图批量制图工作流程。采用ArcPy解决分幅索引图层的生成、制图模板的选择和成果的批量输出,较好地解决了人工选择自定义分幅专题地图的图纸尺寸的难点,实现了基于分幅索引图层的图纸尺寸自动化选择;使用数据驱动页面提供的动态文本插入功能、范围指示器和相邻字段地理处理工具,实现了专题地图整饰信息和成图范围的自动更新。在批量生成土地利用现状图成果的过程中,极大地提高了作业人员的效率和成果的精确性与准确度,为专题地图自动化制图提供了新方法。

According to the problem that custom tile thematic maps cannot be exported in batches,a new batch mapping workflow of thematic maps is proposed.Use ArcPy to solve the generation of tile index layers,the selection of mapping templates,and the batch output of results,it solves the difficulty of manually selecting the paper size of the custom tile thematic map and automated paper size selection based on tile index layers.Using dynamic text,extent indicators and calculate adjacent fields geoprocessing tool to realize the automatic update of thematic map decoration information and map range.It greatly improves the efficiency of the operator and the precision and accuracy of the results in the process of producing the results of the land use status map,and provides new ideas for the automated mapping of thematic maps.
