Terravision : technical analysis and it's application in building global massive spatial data management system 技術(shù)分析及其在全球海量空間數(shù)據(jù)管理中的應(yīng)用
The system have powerful ability of spatial data management computation and analysis 使應(yīng)用軟件不僅具有強大的空間數(shù)據(jù)管理功能,而且還具有強大計算和分析功能。
80 percent or above of the system data has its spatial property, moreover the application of the spatial data management is very popular 80%以上的數(shù)據(jù)都具有空間屬性,而對這些空間數(shù)據(jù)的管理已經(jīng)應(yīng)用十分廣泛。
The author models a new type spatial data for dm3, and based on the model, enlarges dm3 action on spatial data management 隨后,本課題借助現(xiàn)有成熟的空間數(shù)據(jù)庫技術(shù)成果,針對國產(chǎn)數(shù)據(jù)庫dm3特點提出了提出基于dm3的空間數(shù)據(jù)庫解決方案。
This paper also studyed a method to store spatial data into oracle nested tables . this method provide a new scheme of spatial data management 同時,本文還研究了利用oracle嵌套表進行空間數(shù)據(jù)的存儲和管理等問題,為gis空間數(shù)據(jù)管理提供了一種新的解決方案。
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:本文介紹了一種面向自主車輛導航的地理信息系統(tǒng)的系統(tǒng)結(jié)構(gòu)及空間數(shù)據(jù)管理方法.利用面向?qū)ο蠹夹g(shù),對地形模型和空間數(shù)據(jù)管理模型進行抽象.建立了框架式的類體系,并在此基礎(chǔ)上實現(xiàn)了系統(tǒng)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)在對比、分析gis系統(tǒng)空間數(shù)據(jù)管理四種模式的基礎(chǔ)上,提出采用對象?關(guān)系數(shù)據(jù)庫來實現(xiàn)對城市防震減災信息管理與智能分析系統(tǒng)圖形數(shù)據(jù)和屬性數(shù)據(jù)的統(tǒng)一管理,并以arcinfo8.1的personalgeodatabase為例論述了空間數(shù)據(jù)庫的設(shè)計方法和開發(fā)步驟。
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 在相關(guān)理論研究的基礎(chǔ)上,設(shè)計了一個基于j2ee的空間數(shù)據(jù)挖掘原型系統(tǒng)。系統(tǒng)是以通用空間數(shù)據(jù)庫為核心,包含三個功能模塊:空間數(shù)據(jù)管理和人機交互模塊;空間數(shù)據(jù)挖掘模塊(spatialdatamining,sdm);數(shù)據(jù)庫服務(wù)模塊。
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 本文首先介紹了國內(nèi)外空間數(shù)據(jù)庫當前發(fā)展動態(tài),其中主要介紹空間數(shù)據(jù)庫相關(guān)技術(shù):空間數(shù)據(jù)模型、空間查詢優(yōu)化處理、空間數(shù)據(jù)庫管理技術(shù)等國內(nèi)外研究現(xiàn)狀,得出空間數(shù)據(jù)和屬性數(shù)據(jù)在數(shù)據(jù)庫體系下統(tǒng)一存儲管理為空間數(shù)據(jù)庫發(fā)展的必然趨勢。
