随着数据库更新技术和方法的出现，对土地调查数据库的应用越来越多，更多地体现出土地调查数据库的缺陷和错误，以及由于数据精度不同造成的碎线、碎面、缝隙、线面拓扑关系和线状地物穿越图斑，由于检查软件不同造成的数据库汇总面积和表格汇总面积的差别等问题。为了更好利用土地调查数据库生成变更成果，满足更新上报软件的检查，本文提出了快速解决土地调查数据库的拓扑错误、汇总表格错误、数据库椭球面积计算和平差、数据库属性值错误的解决方1法。
隨著數據庫更新技術和方法的齣現，對土地調查數據庫的應用越來越多，更多地體現齣土地調查數據庫的缺陷和錯誤，以及由于數據精度不同造成的碎線、碎麵、縫隙、線麵拓撲關繫和線狀地物穿越圖斑，由于檢查軟件不同造成的數據庫彙總麵積和錶格彙總麵積的差彆等問題。為瞭更好利用土地調查數據庫生成變更成果，滿足更新上報軟件的檢查，本文提齣瞭快速解決土地調查數據庫的拓撲錯誤、彙總錶格錯誤、數據庫橢毬麵積計算和平差、數據庫屬性值錯誤的解決方1法。

With the advent of the database update technology and method ,and the more application in land survey database , there are more defects and errors reflects in land survey database ,and some problems just as broken line ,broken face ,cracks , as well as crossing polygons in line surface topology and linear features caused by different data accuracy ,and the difference between database summary area and summary table area caused by difference checking software have been coming .In order to make better using of the land survey database generates change results ,meeting the reporting software inspection ,this paper puts forward the solution for solving errors of topology ,land survey database ,database summary table error ellipsoid area calculation and adjustment ,and database property value .
