利用数据库质量检查软件、ArcGIS、Access修改土地利用调查数据库的方法

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。

Use of the Database Quality Check Software,ArcGIS,Access to Modify Land Use Survey Database

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 .
