【摘要】：嵌入式GIS系統(tǒng)以智能移動終端設備為平臺,通過對多種技術(shù)的結(jié)合,能夠隨時隨地為人們提供與位置信息相關(guān)的服務。如何將海量的空間信息和強大的應用服務功能擴展到移動終端上,以滿足移動用戶隨時、隨地對空間信息服務的需求,已經(jīng)成為當前地理信息領(lǐng)域內(nèi)研究的熱點。隨著GIS技術(shù)、移動定位技術(shù)、無線通信技術(shù)的不斷發(fā)展,為移動空間信息服務的發(fā)展提供了新的契機。 嵌入式GIS系統(tǒng)的最基本的功能就是導航功能,本文在分析嵌入式GIS系統(tǒng)關(guān)鍵技術(shù)的基礎上,針對空間信息方便存儲和快速顯示的需求研究了電子地圖數(shù)據(jù)的組織結(jié)構(gòu)；針對空間數(shù)據(jù)尤其是導航道路數(shù)據(jù)變化快,現(xiàn)有數(shù)據(jù)更新周期長、現(xiàn)勢性差的特點研究了空間數(shù)據(jù)的增量式更新技術(shù)。 本文的研究工作主要包括以下幾方面的內(nèi)容： 1、通過大量閱讀其他學者的研究文獻,學習了嵌入式GIS的相關(guān)技術(shù)：移動終端操作系統(tǒng)技術(shù)、路徑規(guī)劃技術(shù)、公交查詢技術(shù)、電子地圖數(shù)據(jù)結(jié)構(gòu)、電子地圖在移動終端的調(diào)度與快速顯示技術(shù)和導航電子地圖的增量更新技術(shù)等。 2、在深入學習嵌入式GIS的相關(guān)技術(shù)的同時進行歸納總結(jié),并設計了一種適用于嵌入式終端的電子地圖數(shù)據(jù)存儲結(jié)構(gòu),并研究了增量更新技術(shù)。 3、綜合分析人們對嵌入式GIS的需求,設計一個具備基本功能的嵌入式GIS系統(tǒng)。 4、利用已有知識結(jié)合相關(guān)技術(shù)實現(xiàn)這個嵌入式GIS系統(tǒng)。 5、對嵌入式GIS的未來發(fā)展做出展望。
[Abstract]:The embedded GIS system takes the intelligent mobile terminal equipment as the platform, through the combination of various technologies, How to extend the massive spatial information and the powerful application service function to the mobile terminal, in order to meet the mobile user's demand for the spatial information service at any time, anywhere. With the development of GIS technology, mobile location technology and wireless communication technology, it provides a new opportunity for the development of mobile spatial information services. The most basic function of the embedded GIS system is the navigation function. Based on the analysis of the key technology of the embedded GIS system, this paper studies the organization structure of the electronic map data according to the requirement of convenient storage and fast display of the spatial information. According to the characteristics of spatial data, especially navigation road data, such as fast change, long updating period and poor present situation, the incremental updating technology of spatial data is studied. The research work of this paper mainly includes the following aspects:. 1. Through reading a lot of other scholars' research literature, we study the related technologies of embedded GIS: mobile terminal operating system technology, path planning technology, bus query technology, electronic map data structure, The scheduling and fast display technology of electronic map in mobile terminal and incremental updating technology of navigation electronic map, etc. 2. At the same time, the related technologies of embedded GIS are summarized and summarized, and an electronic map data storage structure suitable for embedded terminal is designed, and the incremental updating technology is studied. 3. The requirement of embedded GIS is analyzed synthetically, and an embedded GIS system with basic function is designed. 4. The embedded GIS system is realized by using the existing knowledge and related technology. 5. The future development of embedded GIS is prospected.
