摘 要
隨著信息技術(shù)的發(fā)展，旅游產(chǎn)業(yè)信息化已成為一種必然趨勢(shì)。近年來，中國(guó)旅游業(yè)發(fā)展迅速，但旅游業(yè)的信息化尚處于發(fā)展初期。加入世貿(mào)組織(WTO)后，入境旅游市場(chǎng)將進(jìn)一步擴(kuò)大。日益強(qiáng)調(diào)個(gè)性需求的旅游呼喚一個(gè)能集介紹、導(dǎo)游、組織為一體的電子導(dǎo)游系統(tǒng)。
從需求角度看，無論是宏觀上的決策支持、綜合經(jīng)營(yíng)分析，還是具體業(yè)務(wù)層面的一個(gè)目標(biāo)的定位、一條線路的規(guī)劃，都離不開地理信息的支持；從技術(shù)角度看，隨著計(jì)算機(jī)信息技術(shù)的發(fā)展，尤其是近年來移動(dòng)計(jì)算領(lǐng)域和空間數(shù)據(jù)庫(kù)領(lǐng)域技術(shù)的不斷更新，地理信息技術(shù)（GIS）也在很多方面融入了新的特征。
本文首先對(duì)電子導(dǎo)游概念和國(guó)內(nèi)外應(yīng)用狀況進(jìn)行闡述.然后分析了位置服務(wù)（LBS）技術(shù)和GPRS通信技術(shù)的特點(diǎn)和技術(shù)現(xiàn)狀，論述了它們與地理信息技術(shù)（GIS）相結(jié)合的必要性和可行性。在此基礎(chǔ)上對(duì)系統(tǒng)進(jìn)行需求分析，得出了本系統(tǒng)的數(shù)據(jù)需求和初步的功能需求，同時(shí)提出了結(jié)合GPS定位與GPRS通信的電子導(dǎo)游系統(tǒng)的解決方案。最后，比較和分析了旅游地理信息系統(tǒng)中尋求最佳路徑的兩種算法。
由于電子導(dǎo)游系統(tǒng)涉及的范圍很廣，需要綜合考慮游客實(shí)現(xiàn)旅游行為的各個(gè)環(huán)節(jié)，因此，本系統(tǒng)還有許多需要進(jìn)一步改進(jìn)和完善的地方。但我們相信，在全球數(shù)字化的趨勢(shì)下，這種基于 GPS定位的電子導(dǎo)游系統(tǒng)必將成為新一代旅游信息系統(tǒng)發(fā)展的走向。

Abstract
Tourism has developed rapidly in the past decades. With the development of information technology, the informationization of tourism industry has already become a kind of inevitable trend. In recent years, China's tourism industry has developed rapidly, but its informationization is still at an early stage of development. After joining in the WTO, the international tourist market will further expand. As a result of emphasizing on individualization by international tourists, an Auto-guide System that provides integrated multiple functions such as recommending, guiding and organizing is strongly expected.
Looking from the demand, regardless of is the macroscopic on policy-making support, the comprehensive management analysis, or a concrete service stratification plane goal localization, a line plan, all cannot leave the geography information support; Looking from the technology that, along with the computer information technology development, in recent years moved the computation domain and the spatial database domain technology unceasing renewal in particular, the geography information technology (GIS) also in very variously melts into the new characteristic.
This thesis firstly prospects what is an auto-guide and the usage of the auto-guide at home and abroad. Secondly, some analysis and discussion on the characteristics of location based service and GPRS(General Packet Radio Service) wireless communication. When they combined with the GIS technology, it will provide a great opportunity and market potential for all sides. According to the analysis of the system's requirements we have got the data requirements and the elementary function requirements. Based on this, we set up a sample framework solution for the application of combination of GPS and GPRS. At last, two different algorithms are discussed to make out the best path on the e-map.
Because auto-guide system concerns a lot of fields, the system still has many parts need to be consummated. But we believe that auto-guide system based on GPS technology, which implements the function of Internet Publication, will be the trend of modern ciceroni field.
