利用arcpy检查线状要输的悬挂点，并输出悬挂点图层。

您可以使用ArcPy来检查线状要素的悬挂点，并输出悬挂点图层。以下是一个示例代码，演示了如何实现这一功能：

import arcpy

# 设置工作环境和输入要素类
arcpy.env.workspace = r"C:\path\to\your\geodatabase.gdb"
input_features = "your_line_features"

# 创建空的悬挂点图层
hang_points = arcpy.CreateFeatureclass_management(arcpy.env.workspace, "hang_points", "POINT")

# 添加字段
arcpy.AddField_management(hang_points, "line_oid", "LONG")

# 遍历线状要素，检查悬挂点并添加到悬挂点图层
with arcpy.da.SearchCursor(input_features, ["OID@", "SHAPE@"]) as cursor:
    with arcpy.da.InsertCursor(hang_points, ["SHAPE@", "line_oid"]) as insert_cursor:
        for row in cursor:
            line_oid = row[0]
            line_geometry = row[1]
            
            # 检查起始点是否为悬挂点
            start_point_on_line = line_geometry.firstPoint
            start_point_on_line_geometry = arcpy.PointGeometry(start_point_on_line, line_geometry.spatialReference)
            if not arcpy.GeometryIntersection(start_point_on_line_geometry, line_geometry):
                insert_cursor.insertRow((start_point_on_line, line_oid))
            
            # 检查终点是否为悬挂点
            end_point_on_line = line_geometry.lastPoint
            end_point_on_line_geometry = arcpy.PointGeometry(end_point_on_line, line_geometry.spatialReference)
            if not arcpy.GeometryIntersection(end_point_on_line_geometry, line_geometry):
                insert_cursor.insertRow((end_point_on_line, line_oid))

# 输出悬挂点图层
output_path = r"C:\path\to\output.gdb"
arcpy.CopyFeatures_management(hang_points, output_path + "\\hang_points")

请确保将代码中的路径替换为您自己数据的实际路径。此代码将创建一个名为`hang_points`的新要素类，并将悬挂点添加到其中，然后将其复制到指定的输出路径。悬挂点被定义为线状要素的起始点或终点，不与任何其他要素相交。

希望这可以帮助到您！如果您有任何其他问题，请随时提问。
