arcpy.listfeatureclasses()的用法arcpy.listFeatureClasses()是ArcPy(ArcGIS的Python库)中的一个函数,用于列出当前工作空间中所有的要素类(Feature Classes)。 下面是其基本用法: python import arcpy # 指定工作空间 arcpy.env.workspace ="C:/path/to/workspace" # 使用 listFeatureClasses 函数获取要素类列表 ...
# 需要导入模块: import arcpy [as 别名]# 或者: from arcpy importListFeatureClasses[as 别名]defget_feature_classes(self):"""Get geodatabase feature classes as ordered dicts."""fcs = []ifself.arcpy_found: arcpy.env.workspace = self.path# iterate feature classes within feature datasetsfds = ...
