基于RDBMS的海量数字高程模型系统

RDBMS-BASED SYSTEM FOR MASS DIGITAL ELEVATION MODEL

介绍了用于海量数字高程模型数据的管理、应用分析以及可视化的系统GeoDEMDB,采用部件对象模型技术,实现了数据管理、空间分析和大范围三维场景漫游的集成,并提供了灵活的选择性。

This paper introduced the RDBMS/ORDBMS-based system named GeoDEMDB, which is a part of latest version of Geostar. It has implemented the data managing, analyzing and large scope virtual walking through in an integrated way. The components can be used together or embedded by other application stand alone.
