一体化测绘技术在城市基础地理信息数据更新中的应用

The Integrated Surveying and Mapping Technology in Urban Fundamental Geographic Information Data Update and Application

就一体化测绘技术在基础地理信息数据更新中的应用情况进行了较为全面的分析,简要回顾了一体化测绘技术在数字测绘技术体系建设中的发展过程,分析了内外业一体化与采编一体化和图库一体化技术之间的关系,讨论了内外业一体化技术的变迁,分析了航测采编一体化、图库一体化和集群分布式并行计算等技术在基础地理信息数据更新中的作用。

In this paper,the integrated surveying and mapping technology in urban foundational geographic information data update application undertook relatively comprehensive analysis.It gires a brief review of the integrated Surveying and mapping technology in digital Surveying and mapping technology in building the system development process.It also discusses the analysis the relationship between the inside and outside operation integration,acquisition and edit integration and database and graph integration technology.At last,it discusses the technological change of the inside and outside operation integration.And it analyzes the aerial acquisition and edit integration,database and graph integration and distributed parallel computing with cluster in foundational geographic information data update.
