列出字段:还有一个常用的列出数据的函数是 arcpy.ListFields() 。此函数列出指定数据集的要素类或表中的字段。语法为arcpy.ListFields(dataset, {wild_card}, {field_type})。 列出文件:另一个有用的函数是 arcpy.ListFiles() 。此函数返回工作区中所有文件的列表,通常用于列出不是空间数据集的独立文件,包括CSV...

比如裁剪(clip),缓冲区(buffer),要素类转要素类(feature class to feature class),添加字段(add field)等等。在脚本中你也可以执行ArcToolbox中的所有工具。作为一名程序员需要记住能够使用的工具取决于当前ArcGIS桌面软件的许可级别。创建一个Python脚本执行ArcToolbox中的工具可实现地理处理任务自动化。
