基于ArcPy的ArcGIS数据驱动制图及批量出图--以耕地质量等别评定制图为例

ArcGIS data-driven mapping and batch mapping based on ArcPy--Taking the evaluation of cultivated land quality as an example

土地整治项目中,耕地质量等别评定要求按不同项目、不同专题进行制图,当项目数量较多时,按项目按专题单张出图的传统方式需要耗费大量时间。借助ArcGIS数据驱动模块将同类型不同项目地图统一制图成册,再结合Arc Py编写出图脚本工具并统一按项目输出专题成果地图,改变了传统的耕地质量评定制图的工作模式,实现了耕地质量评定成果图制图流程化、批量化、自动化。其提高了制图内容的统一性、精确性和正确性,大大减少了制图工作量,并明显减少耕地质量评定出图错误出现的概率。

In land improvement projects,cultivated land quality assessment is required to make maps according to different projects and different topics.When the number of projects is large,the traditional way of drawing maps according to projects and specific topics needs a lot of time.With the help of ArcGIS data-driven module,the maps of different projects of the same type were unified into a book,and then combined with ArcPy,the script tool was written and the thematic result maps were uniformly output by project,which changed the traditional working mode of cultivated land quality assessment mapping and realized the automation of processing and mass mapping of cultivated land quality assessment result maps.It improves the uniformity,accuracy and correctness of cartographic content,greatly reduces the workload of cartographic work,and obviously reduces the probability of mapping error in cultivated land quality assessment.
