土地房产基础地理信息系统建库中的质量控制探讨

Quality Controls for Land and Housing Fundamental GIS Database Development

在土地房产地理信息系统工程实践基础上,从空间数据的质量控制、属性数据的质量控制、空间数据之间的关系的质量控制以及空间数据与属性数据之间关联的质量控制等方面,探讨了土地房产基础地理信息系统数据采集和建库中有关质量控制问题,并提出了一些质量控制的方法和措施。

Based on th e practical project of geographic information system engineering,the paper dis-cusses the quality controls in the land and housing fundamental GIS development for spatial data,at-tribute data,the relationship between spatial data,and the relationship between spatial data and attribute data.The methodologies and measures for data quality control are presented in this paper that is helpful to ensure the reliability of the fundamental data.
