1:50000正射影像数据检查库设计及实现

Design and Implementation of DOM Checking Database for Updating 1:50 000 Topographic Database

国家1:50 000基础地理信息数据库更新工程正射影像数据库是1:50 000数据库更新工程建设的重要组成部分。为保证正射影像数据各项指标符合项目设计要求,保证入库数据的质量,并为今后进一步更新提供依据,设计正射影像数据检查库,并在1:50 000 DOM更新工程中实施和应用,实现了正射影像数据入库检查的程序化处理和自动质量评判。

The high resoluliuu digital ortho-imagc database is an important part for updating national l：50 000 topographic database. In order to ensure DOM data meeting technical index, assure its quality, and provide reference for further updating, this paper designed the DOM checking database, and applied in the implementation of 1：50 000 DOM updating. And it realized the program processing and automatic quality evaluating for ortho image database warehousing cheek.
