importarcpy 1. 读取NetCDF数据并创建栅格图层 使用MakeNetCDFRasterLayer_md函数可以读取NetCDF数据并创建栅格图层。该函数的基本语法如下: MakeNetCDFRasterLayer_md(in_netCDF_file,variable,x_dimension,y_dimension,out_raster_layer,{band_dimension},{dimension_values},{value_selection_method}) 1. 参数说明:...
Each map layer has the following options: All Features—The extent of all features in the layer. Selected Features—The extent of the selected features in the layer. Visible Features—The extent of the visible features in the layer. Note: ...

When creating a network analysis layer in a Python script, you must first explicitly set the workspace environment to a file geodatabase where you want the layer's data to be stored using arcpy.env.workspace = "<path to file gdb>". When the layer is created, a new feature dataset ...
