This paper defines a lot of spatio - temporal analysis operations and describes them in different kinds . we also describe some algorithms of typical spatio - temporal analysis operations in detail 本文對大量的時空操作進(jìn)行了定義和分類描述,同時對stadbsii中實現(xiàn)的一些典型的時空操作的具體算法進(jìn)行了詳細(xì)的描述。
For the development of temporal - spatial gis , the paper proposes a temporal - subsection topological model , and completes the identification of its characteristic . finally , the paper applies the temporal - subsection topological model to the temporal analysis of tgis 同時,為了促進(jìn)時空gis ( tgis )的發(fā)展,提出了時間拓?fù)淠P?時段拓?fù)淠P偷脑O(shè)想,并進(jìn)行了模型的構(gòu)建,模型矩陣特征的證明等,在最后還將模型應(yīng)用到了tgis系統(tǒng)分析中。
The underlayer spatial database of stadbsii is based on realms and supports dual grid techonology . it can express spatial object discretely and avoid the complexity of spatial redrawing . the underlayer support makes it easier to implement efficient spatio - temporal management and spatio - temporal analysis operations Stadbsii系統(tǒng)的底層空間數(shù)據(jù)庫以realms為基礎(chǔ),同時采用了雙網(wǎng)格技術(shù),在離散表示空間對象的基礎(chǔ)上避免了復(fù)雜的空間調(diào)整,為實現(xiàn)高效的時空存取以及時空分析操作提供了底層保證。
The whole paper can be divided into 6 parts : chapter 1 preface : this chapter gives a brief introduction of the relative conceptions , the program construction backgrounds , the review of the present domestic studies in land price information system , the practical significance and the configuration of this paper . chapter 2 study on the construction of land price information system : this chapter deals with the systematic analysis and the general design of the development of land price information system in detail , and on these bases the further systematic function design and data design are proposed . chapter 3 the realization of land price arrangement in land price information system : this chapter deals with the practical methods of some key techniques in land price information inspection system , which are the establishing and updating of land price inspection spots , and the spatial and temporal analysis of land prices , the real time evaluation of land 本論文分為六個部分:第一章:緒論:簡要介紹地價信息系統(tǒng)的相關(guān)概念、項目建設(shè)背景、國內(nèi)目前研究的現(xiàn)狀及研究成果、本項目研究的現(xiàn)實意義以及論文組織;第二章:地價信息系統(tǒng)建設(shè)的研究:從系統(tǒng)的角度出發(fā),對地價信息系統(tǒng)的開發(fā)進(jìn)行詳細(xì)的系統(tǒng)分析、系統(tǒng)總體設(shè)計,在此基礎(chǔ)上進(jìn)行系統(tǒng)的功能設(shè)計和數(shù)據(jù)庫設(shè)計;第三章:地價信息系統(tǒng)地價管理功能實現(xiàn)方法的研究:詳細(xì)論述地價信息系統(tǒng)建設(shè)中一些關(guān)于地價動態(tài)監(jiān)測體系計算機系統(tǒng)的關(guān)鍵技術(shù)的實現(xiàn)方法,主要是地價監(jiān)測點的設(shè)立與更新、地價的時空分析、宗地地價的實時評估等;第四章:地價信息系統(tǒng)地價信息發(fā)布功能實現(xiàn)方法的研究:詳細(xì)論述地價信息發(fā)布的基礎(chǔ)技術(shù)及實現(xiàn)方法;第五章:張家港市地價信息系統(tǒng)建設(shè)的實例:簡要介紹實際參與的張家港市地價信息系統(tǒng)建設(shè)的一些情況;第六章:結(jié)語與討論:總結(jié)論文研究的成果,分析存在的問題,討論進(jìn)一步研究的方向。
