arcgis拓扑检查

拓扑检查单个图层是否重叠（Must notoverlap）：打开ArcCatalog，mdb库中新建Topology,选择需要检查的图层，设置容差，添加检查规则Must notoverlap。完成之后将拓扑加到GIS中即可查看。类似还有其他检查规则：Must not overlap禁止重叠Must not have gaps不许有间隔Must not overlap with禁止要素类间重叠Must be covered by feature class of必须被要素类覆盖Must cover each other须相互覆盖Must be covered by必须被覆盖BoundaryMust be covered by边界必须被覆盖AreaBoundaryMust be covered by区域边界必须被其他边界覆盖
