Terravision : technical analysis and it's application in building global massive spatial data management system 技术分析及其在全球海量空间数据管理中的应用
The system have powerful ability of spatial data management computation and analysis 使应用软件不仅具有强大的空间数据管理功能,而且还具有强大计算和分析功能。
80 percent or above of the system data has its spatial property, moreover the application of the spatial data management is very popular 80%以上的数据都具有空间属性,而对这些空间数据的管理已经应用十分广泛。
The author models a new type spatial data for dm3, and based on the model, enlarges dm3 action on spatial data management 随后,本课题借助现有成熟的空间数据库技术成果,针对国产数据库dm3特点提出了提出基于dm3的空间数据库解决方案。
This paper also studyed a method to store spatial data into oracle nested tables . this method provide a new scheme of spatial data management 同时,本文还研究了利用oracle嵌套表进行空间数据的存储和管理等问题,为gis空间数据管理提供了一种新的解决方案。
Abstract : the architecture of gis for navigation of autonomous vehicle and the management method of spatial data are presented in the paper . by using the object-oriented technique , class library is designed . which is the abstract of terrain model and spatial data management model . and the system is built on base of the class library 文摘:本文介绍了一种面向自主车辆导航的地理信息系统的系统结构及空间数据管理方法.利用面向对象技术,对地形模型和空间数据管理模型进行抽象.建立了框架式的类体系,并在此基础上实现了系统功能
3 by analyzing and comparing following four kinds of patterns in spatial data management of the gis system, the method of unifying management of graphic and property data in object-relation database is proposed, and the personal geodatabase of arcinfo8.1 is used to illustrate the designing method and developing steps of the spatial database (三)在对比、分析gis系统空间数据管理四种模式的基础上,提出采用对象?关系数据库来实现对城市防震减灾信息管理与智能分析系统图形数据和属性数据的统一管理,并以arcinfo8.1的personalgeodatabase为例论述了空间数据库的设计方法和开发步骤。
On the base of the relative theories above, we design a spatial data mining prototype system based on j2ee, which includes three functional modules : spatial data management and interactive module based on web-gis, sdm ( spatial data mining ) module, and database service module 在相关理论研究的基础上,设计了一个基于j2ee的空间数据挖掘原型系统。系统是以通用空间数据库为核心,包含三个功能模块:空间数据管理和人机交互模块;空间数据挖掘模块(spatialdatamining,sdm);数据库服务模块。
Finally, this paper introduces the status of arts of the spatial database ( sdb ) development . and presents sdb key technology such as spatial data modeling, query, optimizing and spatial data management technology . it is concluded that the development direction of sdb that geo-data and attribute data be managed under sdbms 本文首先介绍了国内外空间数据库当前发展动态,其中主要介绍空间数据库相关技术:空间数据模型、空间查询优化处理、空间数据库管理技术等国内外研究现状,得出空间数据和属性数据在数据库体系下统一存储管理为空间数据库发展的必然趋势。
