【摘要】：地理市情監(jiān)測是地理國情監(jiān)測的組成部分,基本地理市情監(jiān)測數(shù)據(jù)庫是地理市情普查的重要工作內容,具有多源、海量、多尺度、多時態(tài)的特點,有效合理組織管理這些數(shù)據(jù),對普查的基本地理市情監(jiān)測數(shù)據(jù)進行組織與管理,構建基本地理市情監(jiān)測數(shù)據(jù)庫,為地理市情監(jiān)測服務建立了基礎數(shù)據(jù),強化了數(shù)字城市的服務功能。 基本地理市情監(jiān)測數(shù)據(jù)庫主要包括地形地貌數(shù)據(jù)庫、地表覆蓋數(shù)據(jù)庫、地理界線數(shù)據(jù)庫,對數(shù)據(jù)庫內容、數(shù)據(jù)特點和數(shù)據(jù)之間的關系進行了分析研究,初步建立了基本地理市情監(jiān)測數(shù)據(jù)庫與基礎地理信息數(shù)據(jù)庫、數(shù)字城市地理空間框架數(shù)據(jù)庫之間的關系,以及基于數(shù)字城市的基本地理市情監(jiān)測應用服務總體結構。 多版本基本地理市情監(jiān)測數(shù)據(jù)要素關聯(lián)和匹配是基本地理市情監(jiān)測數(shù)據(jù)庫數(shù)據(jù)組織管理的關鍵技術問題。從粗匹配和精匹配兩方面研究了多版本要素之間的匹配方法。按照設定的規(guī)則將版本數(shù)據(jù)映射到統(tǒng)一的網(wǎng)格上,通過網(wǎng)格關聯(lián)實現(xiàn)多版本要素的粗匹配,分析了網(wǎng)格大小對粗匹配精度的影響和最優(yōu)網(wǎng)格單元的確定方法。從點匹配、線匹配、面匹配三個方面研究多版本基本地理市情監(jiān)測要素的精匹配策略,對粗匹配結果進行特征判斷,實現(xiàn)要素精匹配。以多版本居民地要素為例,通過粗匹配、精匹配處理,建立起了多版本居民地要素之間的關聯(lián),并結合應用,實現(xiàn)了多版本居民地的變化信息提取,驗證了要素關聯(lián)和匹配方法。 基于對基本地理市情監(jiān)測數(shù)據(jù)庫內容、特點、數(shù)據(jù)關系的研究,構建了基本地理市情監(jiān)測數(shù)據(jù)庫組織結構,應用Geodatabase空間數(shù)據(jù)庫構建了基本地理市情監(jiān)測數(shù)據(jù)庫。對基本地理市情監(jiān)測應用系統(tǒng)進行了總體設計,給出了應用系統(tǒng)體系結構和開發(fā)技術路線。應用ArcGIS Engine,在ArcGIS環(huán)境進行了基本地理市情監(jiān)測應用系統(tǒng)開發(fā),實現(xiàn)了數(shù)據(jù)庫管理、數(shù)據(jù)加載、鷹眼顯示等功能,以及基本地理市情監(jiān)測數(shù)據(jù)的查詢、統(tǒng)計功能。 論文從地理市情監(jiān)測本底數(shù)據(jù)庫數(shù)據(jù)內容、特點、數(shù)據(jù)關系、多版本要素關聯(lián)和匹配,以及基本地理市情監(jiān)測數(shù)據(jù)庫建庫和應用系統(tǒng)方面,對地理市情監(jiān)測本底數(shù)據(jù)庫的數(shù)據(jù)組織管理和應用系統(tǒng)開發(fā)進行了較為系統(tǒng)的研究,對于正在進行的地理國情普查具有一定的參考價值。
[Abstract]:Geographical market situation monitoring is an integral part of geographical situation monitoring. The basic geographical market situation monitoring database is an important work content of geographical market situation survey. It has the characteristics of multi-source, mass, multi-scale and multi-tense, effectively and reasonably organizes and manages these data, organizes and manages the basic geographical market situation monitoring data, constructs the basic geographical market situation monitoring database, and establishes the basic data for the geographical market situation monitoring service. It strengthens the service function of digital city. The basic geographical market monitoring database mainly includes terrain and geomorphology database, surface coverage database and geographical boundary database. The content of the database, the characteristics of the data and the relationship between the data are analyzed and studied. The relationship between the basic geographical market monitoring database and the basic geographic information database and the digital urban geo-spatial framework database is preliminarily established. And the basic geographical market situation monitoring application service structure based on digital city. The association and matching of multi-version basic geographical market monitoring data elements is the key technical problem in the data organization and management of basic geographical market monitoring database. The matching method between multi-version elements is studied from two aspects of rough matching and fine matching. According to the set rules, the version data is mapped to the unified grid, and the rough matching of multi-version elements is realized by grid association. The influence of grid size on the accuracy of rough matching and the determination method of optimal grid element are analyzed. From three aspects of point matching, line matching and surface matching, this paper studies the fine matching strategy of multi-version basic geographical market monitoring elements, judges the characteristics of rough matching results, and realizes the fine matching of elements. Taking the multi-version residential land elements as an example, through rough matching and fine matching processing, the correlation between the multi-version resident land elements is established, and combined with the application, the change information extraction of the multi-version residential land is realized, and the element association and matching method is verified. Based on the research on the content, characteristics and data relationship of the basic geographical market situation monitoring database, the organizational structure of the basic geographical market situation monitoring database is constructed, and the basic geographical market situation monitoring database is constructed by using Geodatabase spatial database. The application system of basic geographical situation monitoring is designed, and the architecture and development technical route of the application system are given. The basic geographical market monitoring application system is developed by using ArcGIS Engine, in ArcGIS environment, and the functions of database management, data loading, hawk eye display, query and statistics of basic geographical market monitoring data are realized. This paper makes a systematic study on the data organization, management and application system of the background database of geographical market monitoring from the aspects of data content, characteristics, data relationship, multi-version element association and matching, as well as the establishment and application system of the basic geographical market monitoring background database, which has certain reference value for the ongoing survey of geographical national conditions.
