【摘要】：隨著地理信息技術(shù)的發(fā)展，依托空間信息的管理方式已經(jīng)成為了各個(gè)領(lǐng)域研究的熱點(diǎn)，為校園的數(shù)字化建設(shè)引入了新的思想。校園現(xiàn)有管理信息系統(tǒng)雖然為校園數(shù)字化建設(shè)做出了貢獻(xiàn)，但是這些系統(tǒng)管理方式陳舊、各自為政、相互對(duì)立、系統(tǒng)異構(gòu)，很難實(shí)現(xiàn)校園寶貴數(shù)據(jù)資源的交互與共享。即使有些校園已經(jīng)構(gòu)建了自己的地理信息系統(tǒng)，并將GIS引入到對(duì)校園的管理上，但是仍然存在結(jié)構(gòu)單一、擴(kuò)展性差、不能與校園現(xiàn)有的管理信息系統(tǒng)進(jìn)行無(wú)縫集成等問題，很難滿足現(xiàn)代“智慧校園”的建設(shè)要求。因此本文以構(gòu)建一個(gè)架構(gòu)優(yōu)越、擴(kuò)展性強(qiáng)、便于集成的通用的校園WebGIS模型為目標(biāo)，對(duì)模型的設(shè)計(jì)思路和實(shí)現(xiàn)方法進(jìn)行了探究。 首先，本文對(duì)校園中的空間實(shí)體對(duì)象進(jìn)行分類，，分析空間對(duì)象的層次組織模型，并在此基礎(chǔ)上抽象出了基于校園空間對(duì)象層次結(jié)構(gòu)以及空間關(guān)系的校園空間模型。依據(jù)此模型和校園地理信息系統(tǒng)的特點(diǎn)以及ArcGISServer的體系結(jié)構(gòu)，設(shè)計(jì)出了包含交互層、業(yè)務(wù)邏輯層和數(shù)據(jù)層三層結(jié)構(gòu)的校園WebGIS通用邏輯模型。 其次，本文給出了校園WebGIS邏輯模型中三個(gè)層次的詳細(xì)設(shè)計(jì)。交互層中，將基于MVC設(shè)計(jì)模式的Cairngorm框架引入到WebGIS客戶端設(shè)計(jì)上；業(yè)務(wù)邏輯層中，通過對(duì)Web服務(wù)器和GIS服務(wù)器處理客戶端請(qǐng)求機(jī)制的研究，總結(jié)出了校園WebGIS交互層與業(yè)務(wù)邏輯層進(jìn)行交互從而完成相應(yīng)業(yè)務(wù)處理和GIS服務(wù)處理的實(shí)現(xiàn)原理；數(shù)據(jù)層中，結(jié)合校園現(xiàn)有管理信息系統(tǒng)屬性數(shù)據(jù)庫(kù)和地理信息系統(tǒng)空間數(shù)據(jù)庫(kù)的特點(diǎn)，給出了屬性數(shù)據(jù)與空間數(shù)據(jù)進(jìn)行無(wú)縫集成的解決方案。 最后，依據(jù)本文提出的校園WebGIS通用模型，以燕山大學(xué)資產(chǎn)管理的數(shù)字化建設(shè)為背景，利用Flex、.NET和SQLServer等技術(shù)，在ArcGIS平臺(tái)上設(shè)計(jì)并實(shí)現(xiàn)了燕山大學(xué)資產(chǎn)導(dǎo)航系統(tǒng)，實(shí)現(xiàn)了從模型到原型系統(tǒng)的映射。實(shí)驗(yàn)結(jié)果表明，本文提出的校園WebGIS模型具有正確性、通用性和實(shí)踐價(jià)值。
[Abstract]:With the development of geographic information technology, relying on the management of spatial information has become a hot topic in various fields, and a new idea has been introduced for the digital construction of campus. Although the existing campus management information system has made a contribution to the construction of campus digitization, these systems are old, separate, antagonistic and heterogeneous, so it is difficult to realize the exchange and sharing of valuable data resources on campus. Even though some campuses have built their own GIS and introduced GIS to the management of the campus, there are still some problems, such as single structure, poor expansibility, unable to integrate seamlessly with the existing campus management information system, etc. It is difficult to meet the requirements of the construction of modern "intelligent campus". Therefore, this paper aims at constructing a general campus WebGIS model with superior architecture, strong expansibility and easy integration, and probes into the design idea and implementation method of the model. Firstly, this paper classifies the spatial entity objects in the campus, analyzes the hierarchical organization model of the spatial objects, and then abstracts the campus spatial model based on the hierarchical structure of the campus spatial objects and the spatial relations. According to this model, the characteristics of campus GIS and the architecture of ArcGISServer, a campus WebGIS general logic model with interaction layer, business logic layer and data layer is designed. Secondly, this paper gives the detailed design of three levels of campus WebGIS logic model. In the interaction layer, the Cairngorm framework based on MVC design pattern is introduced into the design of WebGIS client, and in the business logic layer, the mechanism of handling client request by Web server and GIS server is studied. The realization principle of the campus WebGIS interaction layer interacting with the business logic layer to complete the corresponding business processing and GIS service processing is summarized. According to the characteristics of the existing attribute database of campus management information system and the spatial database of geographic information system, the solution of seamless integration of attribute data and spatial data is presented. Finally, according to the campus WebGIS general model proposed in this paper, taking the digital construction of Yanshan University asset management as the background, using the technology of Flex,.NET and SQLServer, this paper designs and implements the Yanshan University assets navigation system on the ArcGIS platform. The mapping from model to prototype system is realized. The experimental results show that the proposed campus WebGIS model is correct, universal and practical.
