Arcgis Engine的拓扑检查类

使用方式#

TopologyChecker topocheck = new TopologyChecker(mainlogyDataSet);//传入要处理的要素数据集
topocheck.PUB_TopoBuild("testTopo2");//构建拓扑的名字
topocheck.PUB_AddFeatureClass(null);//将该要素中全部要素都加入拓扑
//添加规则
topocheck.PUB_AddRuleToTopology(TopologyChecker.TopoErroType.点要素之间不相交, (topocheck.PUB_GetAllFeatureClass())[2], (topocheck.PUB_GetAllFeatureClass())[0]);
//获取生成的拓扑图层并添加
axMapControl1.Map.AddLayer(topocheck.PUB_GetTopoLayer());
axMapControl1.ActiveView.Refresh();
