WebGIS為Internet與GIS的整合應用。藉由網際網路相關技術的進步與發展,使得GIS得以擴大了本身的應用範圍,成為一個大眾化的工具。透過網際網路,使用者可以對WebGIS伺服器提出查詢要求,由伺服器處理此查詢要求,並將查詢結果回傳給使用者。然而受限於網際網路“有線”的服務範圍,WebGIS的應用範圍仍侷限於室內的作業環境。因此,WebGIS若能結合行動裝置與無線通訊技術,將可以有效擴大WebGIS的應用範圍。
本研究設計與規劃一套整合行動裝置WebGIS之系統架構,重點偏向於伺服器端系統架構與功能開發。本研究參考WebGIS之相關研究(GiMoDig),建立一個四層式系統架構。系統架構具有良好的擴充性,易於擴充系統服務項目與資料來源。遵循OGC標準規範OpenLS,建立行動裝置與伺服器間資料傳輸的作業模式,包括資料傳輸方式、傳輸格式以及傳輸內容。地理資料格式則採用OGC制定之GML3.0,適合推廣於開放式地理資料環境,達成地理資料的交流與共享。最後本研究使用JAVA程式語言實作開發出整個系統架構與各項功能,並透過系統測試,驗證了此系統架構之可行性。本研究提出數點結論與建議,可以做為未來發展行動式地理資訊系統之參考。
WebGIS is the integration of Internet and GIS. By the development and advancement of Internet, GIS extends itself field of application, and becomes a public tool. By internet, the user can make a request to a WebGIS server. The WebGIS Server processes the request and then response the result to the user. However, due to the constraint of wired Internet, the field of application of WebGIS is restricted to indoor environment. Therefore, WebGIS that integrate with mobile devices and wireless communication technology will extend the field of application of WebGIS efficiently.
This research designed a system archetcure for integration of mobile devices and WebGIS. The main tasks are system architecture and function develpement for server-side. Referring to related research about WebGIS –GiMoDig, we designed a 4-tier system architecture. This system architecture is easy to extend its service and data source because of its high extensibility. In compliance with OGC’s standard –OpenLS, we build a model of data transmission between client and server, including data transmission method, data format, and data content. We used OGC’s GML3.0 to be our geographic data format, which is easy to extend in open GIS data environment. Finally, this research implemented entire system architecture and system function by using JAVA program language, then we verified the feasibility of this system by system test. This research proposed several conclusions and suggestions, which will be a reference of the development of mobile geographic information system in the feature.
