【摘要】:地理信息系統(tǒng)近年來被廣泛關(guān)注,從Google Map的廣泛應(yīng)用,到各個(gè)城市建成了數(shù)字城市,再到行業(yè)應(yīng)用、企業(yè)應(yīng)用,地理信息系統(tǒng)已經(jīng)被廣泛的應(yīng)用在各個(gè)領(lǐng)域用來進(jìn)行數(shù)據(jù)管理、數(shù)據(jù)展示、數(shù)據(jù)分析。過去Desktop GIS采用的C/S結(jié)構(gòu)的架構(gòu),在互聯(lián)網(wǎng)技術(shù)和分布式技術(shù)興起的當(dāng)前,Web GIS目前被廣泛應(yīng)用在各行各業(yè)。隨著三維技術(shù)的發(fā)展,3D GIS也正在逐步的應(yīng)用,,特別是純?nèi)S的應(yīng)用,在數(shù)據(jù)展示方面提供了更真實(shí)的效果。 本文從各種空間地理的概念開始,首先分別介紹了地理學(xué)的概念,其中包括了目前常用的地圖顯示技術(shù),地圖緩沖技術(shù),這將使得在瀏覽和傳輸?shù)貓D的過程中帶來理想的性能。其次,對(duì)整個(gè)GIS系統(tǒng)進(jìn)行了廠區(qū)應(yīng)用過程中的需求和功能分析,確定了不同用戶所要完成的使用需求,包括不同用戶在數(shù)據(jù)采集,數(shù)據(jù)整理,制圖和生成地圖涉及的地理學(xué)方面的內(nèi)容。第三,地里信息系統(tǒng)的核心是數(shù)據(jù),在數(shù)據(jù)存儲(chǔ)方面,論述了空間數(shù)據(jù)庫與普通數(shù)據(jù)庫之間的區(qū)別和空間數(shù)據(jù)的建立方法,并且論述各表之間的聯(lián)系以及所需要的各種屬性表。第四,使用業(yè)界知名廠商ESRI的地理信息系統(tǒng)套件,來實(shí)現(xiàn)這個(gè)廠區(qū)地理信息系統(tǒng)。通過使用ArcGIS Server服務(wù)器,詳細(xì)說明了服務(wù)器的建立和地圖發(fā)布的方法。最后,詳細(xì)說明WebGIS的常用功能的實(shí)現(xiàn)方法,空間分析在實(shí)際應(yīng)用中的實(shí)現(xiàn)過程以及在石油行業(yè)普遍使用的HAZOP分析方法進(jìn)行事故概率的分析。
[Abstract]:Geographic Information system (GIS) has been widely concerned in recent years, from the wide application of Google Map, to the establishment of digital city in every city, to the application of industry, enterprise application, GIS has been widely used in various fields for data management. Data display, data analysis. The architecture of C / S structure used by Desktop GIS in the past, the current web GIS is widely used in various industries with the rise of Internet technology and distributed technology. With the development of 3D technology, 3D GIS is also being applied step by step. In particular, the application of pure three-dimensional data display provides a more realistic effect. This paper begins with various concepts of spatial geography, first introduces the concept of geography, including the current commonly used map display technology, map buffering technology, This will result in ideal performance in the process of browsing and transmitting maps. Secondly, the requirements and functions of the whole GIS system are analyzed in the process of plant application, and the requirements of different users are determined. This includes the geographic aspects of data collection, data collation, mapping and map generation by different users. Third, the core of the field information system is data, and in terms of data storage, This paper discusses the difference between spatial database and general database and the method of establishing spatial data, and discusses the relationship between each table and the various attribute tables needed. 4th, it uses the GIS suite of ESRI, a well-known manufacturer in the industry. Through the use of ArcGIS Server server, the establishment of the server and the method of map publishing are described in detail. Finally, the realization method of the common functions of WebGIS is explained in detail. The realization process of spatial analysis in practical application and the accident probability analysis of HAZOP analysis method which is widely used in petroleum industry are analyzed.
