摘要
极地地理数据具有多尺度、多类型、多时相、海量存储等特点,为满足对极地数据的高效存储管理,采用基于ArcSDE结合Oracle10g的空间数据库建库技术建设极地空间数据库。本文阐述了极地空间数据库的数据模型、数据库结构、主要技术路线和时空数据一体化概念,提出利用分层和要素编码的方案来管理地理数据。
Polar geographical data is featured with multi-scale,multi-type,multi-temporal,mass storage,and etcother characteristics.In order to satisfy the need of highly efficient storage and management of polar data,spatial database technique of ArcSDE combined with Oracle 10g is applied in the building of polar database.we build Polar spatial database by the spatial database technology based on ArcSDE and Oracle10g.This paper elaborates ondescribes the database model,el and the database structure,main technical route and the concept of integration of spatial and temporal data of polar spatial database,and puts forward the idea of managing geographic data using stratification and element coding plan.of Polar spatial database,the main technical route,and the integration of spatial and temporal data.This paper proposed hierarchical,the elements encoding scheme to manage geographic data.
