arcgis使用拓扑检查自重叠的代码

ArcGIS中使用拓扑检查防止数据自相重叠通常是在地图编辑过程中，特别是处理线状和面状数据时。对于自定义拓扑规则，你可以通过ArcObjects API或Python SDK编写脚本来实现。这里是一个基本的Python示例，使用arcpy模块：

import arcpy

# 定义拓扑规则
def check_self_overlap(feature_class):
    # 创建拓扑对象
    topology = arcpy.da.TopologyValidator(feature_class)
    
    # 开启拓扑检查
    topology.enableRules()
    
    # 检查是否存在自相重叠错误
    errors = topology.findErrors("SELF_TOUCHING")
    
    if errors:
        for error in errors:
            print(f"Feature {error.featureID} at row {error.row} has self-overlapping geometry.")
    else:
        print("No self-overlapping features found.")

# 调用函数，传入你要检查的图层或表
check_self_overlap("your_feature_class.shp")
