面向数字城市的空间数据库设计与实现

The Design and Implementation of Spatial Database for Digital City

空间数据库是数字城市空间数据基础设施的核心技术平台。本文在分析面向数字城市空间数据库的特点及功能定位的基础上,提出其核心内容,包括元数据库、遥感影像数据库、电子地图数据库、GPS数据库、地理编码数据库和社会经济基本单元数据库等。同时,对其数据组织模型和接口体系进行设计,并基于J2EE规范和Oracle Spatial进行了初步实现。

Spatial Database is the core technique platform of digital city data infrastructure. This paper discusses the characteristic of spatial database for digital city, and figures out it's function should be data share and interopefability.It mainly consists of metadata database, remote sensing image database, electron vector map database, GPS database, Geocoding database and unit database. At last we design and implement Spatial Database based J2EE and Oracle Spatial for digital city. The main technique includes JPEG2000 compress arithmetic based Jasper and JJ2000 source code, and data update schema.
