【摘要】：本文研究了新時(shí)期基礎(chǔ)地理信息數(shù)據(jù)庫應(yīng)用特點(diǎn),指出了能否實(shí)現(xiàn)快速更新是制約地理信息特別是基礎(chǔ)地理信息應(yīng)用的瓶頸之一。從這個(gè)需求出發(fā),探討了時(shí)態(tài)技術(shù)在基礎(chǔ)地理信息數(shù)據(jù)庫建庫和更新中的應(yīng)用。 本文從地理對(duì)象建模角度,重新審視了現(xiàn)在的地理對(duì)象模型,結(jié)合當(dāng)前技術(shù)的發(fā)展,提出了一種新的面向?qū)ο蟮牡乩韺?duì)象時(shí)態(tài)化思路和模型實(shí)現(xiàn)—時(shí)態(tài)地理對(duì)象立方體模型,并從矢量數(shù)據(jù)庫和柵格數(shù)據(jù)庫兩種形式的數(shù)據(jù)內(nèi)容上實(shí)現(xiàn)了數(shù)據(jù)的時(shí)態(tài)信息存儲(chǔ),為快速更新奠定了一個(gè)堅(jiān)實(shí)的基礎(chǔ)。利用時(shí)態(tài)地理對(duì)象立方體模型,部分的解決了基礎(chǔ)地理信息數(shù)據(jù)庫在歷史數(shù)據(jù)存儲(chǔ)、管理和更新的問題。 通過時(shí)態(tài)地理對(duì)象立方體模型和時(shí)態(tài)數(shù)據(jù)庫的引入,解決傳統(tǒng)GIS由于靜態(tài)空間數(shù)據(jù)對(duì)象管理而形成的短板以及數(shù)據(jù)更新發(fā)布上的的局限,提出一種適應(yīng)物聯(lián)網(wǎng)時(shí)代、滿足智慧城市建設(shè)、防災(zāi)應(yīng)急應(yīng)用需求的具有時(shí)態(tài)特征的基礎(chǔ)地理地理信息數(shù)據(jù)存儲(chǔ)管理和快速更新方法,實(shí)現(xiàn)了基礎(chǔ)地理信息更新、管理、發(fā)布的一體化和時(shí)態(tài)化,為新時(shí)期基礎(chǔ)地理信息服務(wù)快速更新發(fā)布提供了一個(gè)可行的技術(shù)路線,為基礎(chǔ)地理信息更好的利用與時(shí)空分析提供了一個(gè)可行的方案。 本文認(rèn)為：生產(chǎn)與更新沒有本質(zhì)區(qū)別,生產(chǎn)就是更新。突破傳統(tǒng)認(rèn)識(shí)局限,重新設(shè)計(jì)生產(chǎn)過程和流程,將生產(chǎn)、更新過程中四個(gè)生產(chǎn)周期的要素?cái)?shù)據(jù)都存儲(chǔ)在統(tǒng)一的邏輯庫中,不再劃分工作庫與正式庫,實(shí)現(xiàn)測(cè)繪生產(chǎn)任務(wù)和成果離散化。將離散化的生產(chǎn)任務(wù)和成果統(tǒng)一納入數(shù)據(jù)庫管理的范疇,改變傳統(tǒng)的測(cè)繪生產(chǎn)項(xiàng)目管理中,項(xiàng)目通過驗(yàn)收后才將數(shù)據(jù)整體錄入數(shù)據(jù)庫中的方式,將工作數(shù)據(jù)錄入庫中進(jìn)行管理并同時(shí)記錄了過程。 本文研究了基礎(chǔ)地理信息數(shù)據(jù)庫快速更新中的協(xié)同更新和并發(fā)沖突檢測(cè)處理等更新中的關(guān)鍵技術(shù),并提出了自己的協(xié)同更新機(jī)制以及沖突檢測(cè)與消除策略,較好地解決了實(shí)際生產(chǎn)中的問題,提供了實(shí)時(shí)更新的技術(shù)實(shí)現(xiàn)。 文章提供了一個(gè)研究技術(shù)的實(shí)際應(yīng)用--大比例尺時(shí)態(tài)地形圖數(shù)據(jù)庫更新。為城市測(cè)繪生產(chǎn)單位、基礎(chǔ)地理信息管理者、基礎(chǔ)地理信息發(fā)布運(yùn)營者等廣大用戶提供了一個(gè)強(qiáng)有力的工具和可借鑒的技術(shù)方案。
[Abstract]:This paper studies the application characteristics of basic geographic information database in the new period, and points out that rapid updating is one of the bottlenecks that restrict the application of geographical information, especially basic geographic information. This paper discusses the application of temporal technology in database building and updating of basic geographic information database. In this paper, the current geographical object model is reviewed from the point of view of geographical object modeling. Combined with the development of current technology, a new object-oriented temporal object model and its realization, temporal geographic object cube model, are proposed. The temporal information storage is realized from two kinds of data content: vector database and raster database, which lays a solid foundation for fast updating. Part of the solution to the basic geographic information database in the historical data storage, management and update problems. Through the introduction of temporal geographic object cube model and temporal database, this paper solves the limitation of traditional GIS because of static spatial data object management and the limitation of data updating and publishing, and puts forward a new method to adapt to the times of Internet of things. In order to meet the needs of intelligent city construction, disaster prevention and emergency response, the method of storing and managing basic geographic information data with temporal characteristics and rapid updating method has realized the integration and tense of basic geographic information updating, management and release. It provides a feasible technical route for the rapid update and release of the basic geographic information service in the new period, and provides a feasible scheme for the better utilization and spatiotemporal analysis of the basic geographic information. This paper holds that there is no essential difference between production and renewal. Production is renewal. Break through the limitations of traditional knowledge, redesign the production process and process, The data of the elements of the four production cycles are stored in a unified logic base, and no longer separate the work library from the formal library. To realize the discretization of surveying and mapping production tasks and achievements, to unify the discrete production tasks and achievements into the scope of database management, and to change the traditional surveying and mapping production project management, After the project passed the acceptance, the whole data was entered into the database, and the working data was managed and the process was recorded at the same time. In this paper, the key technologies of collaborative update and concurrent conflict detection in the rapid updating of basic geographic information database are studied, and their own cooperative updating mechanism and conflict detection and resolution strategy are put forward. It solves the problems in practical production and provides the technical realization of real-time update. This paper provides a practical application of research technology-updating of large scale temporal topographic map database. General users, such as basic geographic information distribution operators, provide a powerful tool and a technical solution that can be used for reference.
