摘　　要：Python是一种广泛应用于数据分析、数据转换、数据管理的程序设计语言。ArcGIS的ArcPy模块作为ArcGIS Python开发体系的一部分,提供了地理信息数据生产处理接口。为解决某省1∶10000基础地理信息数据处理作业过程中存在耗时长、机械重复同一步骤及人工误操作等技术问题,本文利用ArcPy模块提供的接口,开发了一套可实现数据预处理、分块分发、冗余图层及字段删除、属性非法值检查和缺省值赋值等批量自动化处理工具。实践结果表明,利用该工具可实现数据自动化处理,不仅准确、高效,还大大提高了工作效率。Python is a programming language widely used in data analysis,data conversion and data management.ArcPy module of ArcGIS,as a part of ArcGIS Python development system,provides the interface for geographic information data production and processing.In order to solve the technical problems of time consuming,mechanical repetition of the same step and manual misoperation in the processing of 1∶10000 basic geographic information data in a province,a set of batch automatic processing tools that can realize data preprocessing,block distribution,redundant layer and field deletion,attribute illegal value check,default value assignment,etc.are developed using the interface provided by ArcPy module in this paper.The practice results show that the tool can realize automatic data processing,which is not only accurate and efficient,but also greatly improves the work efficiency.
