摘　　要：地理空间数据具有总量大、空间关系复杂的特点,其质量对空间分析结果准确性和空间决策支持可靠性有重要影响,设计了基于规则定制的质量检查软件,基于算子、要素和参数进行检查规则的设计,并通过对检查规则的灵活配置,形成针对特定地理空间数据质检要求的检查方案。以全国地理国情监测数据为例,研发了地理国情监测数据检查软件,完成了全国地理国情监测数据的质量检查,保证了全国地理国情监测建库工作的顺利完成。结果表明,基于规则定制的数据质量检查软件不仅可以提高地理空间数据检查效率,提升地理空间数据的质量,且通过对检查规则的灵活配置,可形成针对特定地理空间数据的检查方案,以满足不同项目对成果质量控制的需要,可重用性较强,降低了后期维护的成本和难度,具有较强的普适性和推广价值。The total amount of geospatial data is large and its spatial relationship is complex.The quality of geospatial data directly affects the precision of spatial analysis result,which is related to the reliability of various spatial decision support.This paper designed geospatial data quality inspection software based on check rules.The check rules are designed based on algorithm,layers and parameters.Through the flexible configuration of inspection rules,the inspection scheme for specific geospatial data quality requirements was formed.Taking the national geographic conditions monitoring data as an example,this paper developed the data quality inspection software.The quality inspection of national geographic conditions monitoring data has been completed to ensure the smooth completion of national geographic situation monitoring database construction.The results show that the data quality inspection software based on check rules can improve data inspection efficiency and the quality of geospatial data.At the same time,the software can also be used for other geospatial data by changing check scheme according to check rules.It can meet the needs for data quality control of different projects.It reduces the cost and difficulty of later maintenance.It has high practicability and promotion value.
