摘要
MAPGIS作为基础平台目前广泛应用于我国地学空间数据库的建设之中,其空间数据的质量直接影响地学空间数据库的优劣.空间数据的精度,属性数据的正确性与完整性,空间数据拓扑关系的正确性是影响空间数据库质量的主要因素.通过实践总结,阐述了控制上述3方面数据质量的具体手段和方法,从而达到确保数据质量,满足建立地学空间数据库的要求,建成质量优良的地学空间数据库.
As a basic platform,MAPGIS is widely applied during establishing geological spatial databases in China currently.The quality of its spatial data has a directly effect on the function of the geological spatial database.The precision of spatial data,the validity and intagrality of the attribute data and the topo relation of spatial data are the main factors that affect the quality of space database.Based on practical work,the methods for data quality control are studied.With the methods,the data quality can satisfy the request for the establishing of high standard geological spatial databases.
