增量更新技术在新型基础测绘中的应用研究

Research on the Application of Incremental Updating Technology in the New Fundamental Surveying and Mapping

随着我国全面深化改革、"一带一路"等重大国家战略的实施,基础地理信息数据在社会发展和城市规划中的作用也越来越重要。为保证基础地理信息数据的现势性,需要不断对其进行更新。传统的基于基础地理信息数据库的全覆盖式更新不仅效率低,且难以与现存的其他数据库进行融合与联动更新。针对这个问题,结合新型基础测绘建设的内容,将增量更新技术运用到基于数据库的生产更新中,设计并实现了地理要素数据库和数据库管理系统。实验表明,该方法不仅大大提高了基础测绘数据生产更新的效率,还能很好地实现数据版本管理,并能与其他数据库进行联动更新。

As China's comprehensive deepening reform,'The Belt and Road'and other major national strategy of the role of basic geographic information data in the development of society and city planning is more and more important.To ensure the timeliness of basic geographic information data,it need to continue to update.The traditional full coverage update based on the basic geographic information database is not only inefficient,but also difficult to integrate with other existing databases.To solve this problem,it combined with the content of the construction of basic surveying and mapping model,incremental updating technique is applied to production based on the database update,the design and implementation of geographical factor database and database management system.The experimental results show that this method not only can greatly improves the efficiency of the production and updating of basic surveying and mapping data,but also can realize the data version management,and can be linked with other.
