Rule oriented intelligent spatial data quality checking model and realization(面向规则的智能空间数据质检模型及实现)
为了提高空间数据质检的效率,实现要素类间拓扑空间关系的智能检测,提出了面向规则的智能空间数据质检模型(RSTT),重点讨论了RSTT模型体系结构和拓扑规则等核心问题.基于RSTT和四层体系结构模型,以空间数据质检方案的灵活定制、数据批量自动检查和质检规则零编码扩展等为目标,开发了空间数据质检系统LR _Checker.通过近40 G的国土资源空间数据测试表明,应用LR_Checker进行数据检查可大大降低空间数据建库的工作量,并可有效控制数据质量,同时也证明RSTT模型的正确性、有效性和合理性....
