手机执行python脚本_使用python脚本执行地理处理工具！

桌面ArcGIS包含 800多种可在Python脚本中运行的地理处理工具 。

通过Python脚本来运行地理处理工具，可以处理复杂的工作和执行批处理任务。

案例一：使用脚本执行地理处理工具(以 裁剪 为例)

查看帮助文档模仿的代码：

 1 # Name: Clip_Example2.py2 3 # Description: Clip major roads that fall within the study area.4 5 6 # Import system modules7 8 import arcpy9 10 from arcpy import env11 12 13 # Set workspace14 15 env.workspace = "F:【the_path_of_grace】ArcpyBook"16 17  18 # Set local variables19 20 in_features = "data/CityOfSanAntonio.gdb/Burglary"21 22 clip_features = "Ch5/EdgewoodSD.shp"23 24 out_feature_class = "Ch5/ClpBurglary.shp"25 26 xy_tolerance = ""27 28 29 # Execute Clip30 31 arcpy.Clip_analysis(in_features, clip_features, out_feature_class, xy_tolerance)

工作原理：

在Python脚本中，可以参照_语法来调用工具。

注：toolboxalias是工具箱的别名

案例二：将一个工具的输出作为另一个工具的输入

步骤：①缓冲区分析->②创建要素图层->③按位置选择图层
