摘要
针对采用常规方法处理农田灌溉面积一张图操作流程繁琐、过程重复、易出错等问题,该文提出一种基于ArcGIS ModelBuilder的农田灌溉面积一张图建模批处理方法,采用ModelBuilder和Python将一系列空间数据处理工具串联构建批处理工具。该方法在瑞安市、开化县等多个县市区项目中得到了验证,只要事先简单设置参数,即可一键完成多个要素图层的面积计算、数据统计、属性字段赋值等批处理工作,具有运行效率高、准确率高、相比ArcGIS二次开发准入门槛低等特点,大大提高了工作效率,为农田灌溉面积一张图项目按时完成提供保障,也为数字孪生流域数据底板数据库建设提供一种新的作业思路。
Aiming at the problems of cumbersome,repetitive,and error-prone processing of a farmland irrigation area map using conventional methods,this paper proposes a batch processing method for modeling a farmland irrigation area map based on ArcGIS ModelBuilder.A series of spatial data processing tools are connected in series to build a batch processing tool.This method has been verified in projects in multiple counties and cities such as Rui'an City and Kaihua County:As long as parameters are simply set in advance,batch processing work such as area calculation,data statistics,and attribute field assignment of multiple feature layers can be completed with one click.It has high operating efficiency,high accuracy,and low entry threshold compared to the secondary development of ArcGIS.It greatly improves work efficiency,provides a guarantee for the timely completion of a farmland irrigation area map project,and also provides a new operating idea for the construction of a digital twin watershed data backplane database.
