摘要
为了提高空间数据质检的效率,实现要素类间拓扑关系的智能检测,在分析地籍空间数据库要素拓扑关系分类的基础上,提出了基于拓扑规则的拓扑关系验证方法,并采用GIS开发平台ArcEngine,开发了空间数据质检系统LR-Checker。大量地籍空间数据的测试表明,采用LR-Checker可大大降低数据检查的工作量,基于拓扑规则的拓扑关系验证方法是正确、有效和合理的。
In order to enhance the efficiency of spatial data quality checking and realize the intelligent topology relationship testing between feature classes, the topology relationship classification of the cadastral spatial database was analyzed and a topology relationship verification method was proposed based on topology rules. A spatial data quality checking system LR_Checker was developed by using GIS development platform AreEngine. The testing with massive cadastral spatial data indicate that, the use of LR_Checker can greatly reduce the data checking work, and the proposed verification method is accurate, effective and reasonable.
