Based on the above technology, and combined with the powerful extensibility of postgresql, we design and implement a complete spatial database prototype system, called sadbs ii 在此基础上,结合postgresql强大的扩展能力,我们设计并实现了完整的空间分析数据库原型系统,称为sadbs。
This dissertation addresses the geo-spatial data service integration and distributed spatial query issues under web environment from the points of spatial database and information retrieval 论文从空间数据库和信息检索的角度研究了web环境下地理空间数据服务集成和分布式查询问题。
The application of middle-wares in spatial database is discussed . taken arcsde as example, which is produced by esri corporation, it studies the storage and management of spatial data 重点讨论了中间件技术在空间数据库的应用,并以esri公司的arcsde为基础平台,分析了空间数据的存储和管理。
spatial database can supply high-powered capability of storing and managing spatial object, well capability of organizing and restricting spatial data, optimized spatial analysis operation function 空间数据库能够提供高效的空间对象存储管理能力,良好的空间数据组织和约束能力,优化的空间分析操作功能。
With the development and application of database technology and vector map technology , large quantities of spatial data have been produced and stored in spatial database and spatial data warehouse 随着数据库应用技术以及空间数据矢量化技术的迅速发展,人们积累的数据越来越多,大量的空间数据存储在空间数据库中。
The result indicates that it exists many problems in building spatial database that are spatial data structure mode, spatial data security and spatial data updating, therefore, it needs vigorous research 结果表明:空间数据建库还存在空间数据的组织模式、空间数据的安全性、空间数据的快速更新等问题,还需要进行大力研究。
On the base of the database, with mapgis software, the management software of mineral spatial database is developed, which contains abundant information, reasonable structure and several practical functions 在此基础上,以mapgis为平台进行程序编程,建立了数据信息丰富、库结构合理、具有多项实用功能的矿产空间数据库软件。
We implement the function of data replication in relation database system and spatial database system, design the data replication solution project in guangzhou fire protection and communication system 基于研究内容,在试验系统中实现了关系数据库和空间数据库的数据复制功能,提出了在广州消防通信指挥系统中的复制解决方案。
Now the study of the agricultural non-point source pollution is mainly to integrate gis with environmental model . building spatial database is the basement of using gis to study non-point source pollution 目前对农业面源污染的研究主要是将gis作为非常有用的工具结合到环境模型中,而建立空间数据库是利用gis进行面源污染研究的基础。
This paper mainly discusses the way to introduce the middleware of ogsa-dai to spatial database, and to expand client apis interface to implement spatial-data access and integration 摘要提出了一种面向服务的思想,将开放网格服务结构下的数据访问与集成中间件技术引入到空间数据库系统中,扩展了ogsa-dai客户api接口,实现了空间数据的访问和集成。
