大比例尺地形图数据更新入库技术及其应用

Database Updating Technology Based on Large Scale Topographic Map Data and Its Application

基础地理信息数据是"数字惠州"地理空间框架的重要组成部分,随着"数字惠州"的应用推广,不同行业和部门对基础地理信息数据的现势性提出了更高要求。在"数字惠州"地理空间框架建设过程中,设计了一种地形图数据更新入库方法,用于将日常采集或修补测的地形图数据更新到基础地理信息数据库中。

Basic geographic information data is an important part of Geo-spatial Framework of Digital Huizhou.With the wide application of Digital Huizhou,more requirements of basic geographic information data have been proposed in different industries and departments.In the construction of Geo-spatial Framework of Digital Huizhou,a new method of updating database with topographic map data was devised,that updating topographic map data daily acquisition or surveying to basic geographic information database.
