行動裝置整合WebGIS之客戶端功能架構及系統發展

Architecture Design and System Development of Client Side for Mobile Devices Integrated with WebGIS

摘要


隨著行動裝置及無線通訊的普及,利用行動裝置來提供地理資訊服務的需求也日益增加。不過目前行動裝置上之地理圖形應用系統大多為單機作業環境,僅供特定目的使用。而且不同的系統間沒有一個統一的資料標準,造成資料交換與共享上的困難。本研究探討將WebGIS之功能架構整合於行動裝置中,藉由系統功能的發展,提出適合於行動裝置與伺服器間的溝通機制。本研究以GML做為標準的資料交換格式,並以行動資料庫做為屬性資料管理核心。研究成果顯示本文所提之系統功能架構可以有效地擴充行動裝置之WebGIS功能,並且以無線區域網路提供即時之地理資訊服務,突破傳統單機作業之缺點,使得行動裝置具有空間資訊的查詢與分析功能。

With the popularization of mobile devices and wireless communication, the demand for making use of mobile devices to offer geographic information service increases day by day. However, geographically graphic application systems on the mobile devices are mostly stand-alone systems dedicated to a specific purpose. And there is not a unified data standard among different systems, causing the difficulty of data to exchange and share. This research intends to integrate the functional architecture of WebGIS into mobile devices. By developing the function of system, we put forward a suitable method for the communication among the mobile devices and WebGIS server. The research regards GML as the standard of data exchange format, and mobile database as the management core of attribute data. The result shows that functional architecture of this research can augment WebGIS function of mobile devices effectively, and offer geographic information real-time in wireless LAN.
