【正文】 I摘要 本文系統(tǒng)將在 J2ME 平臺下，利用 J2ME 的 JSR179 定位開發(fā)包與 Google 靜態(tài)地圖實現(xiàn)定位、興趣點添加、路線規(guī)劃以及離線地圖定位等功能。在用戶手機硬件支持J2ME 和定位功能的情況下，用戶只要支付少量的 GPRS 流量費即可對用戶的位置進行定位、路線規(guī)劃等功能。另外為了節(jié)省用戶的 GPRS 流量，設(shè)計中也特定開發(fā)了離線地圖模式，在不聯(lián)網(wǎng)的情況下，用戶依然可以進行 GPS 定位。本篇論文將分為七章進行介紹。第一章緒論，介紹課題研究的背景、手機 GPS 導航發(fā)展現(xiàn)狀以及課題研究的主要內(nèi)意和意義；第二章主要對本文系統(tǒng)用的相關(guān)技術(shù)進行介紹；第三、四、五章為本篇論文的重點，詳細闡述了本文系統(tǒng)的需求、詳細設(shè)計以及存在的問題等；第六章為 GPS 手機的發(fā)展前景展望；第七章則是本篇論文的總結(jié)?！娟P(guān)鍵詞】 J2ME，MIDP，GPS，JSR179，Google 靜態(tài)地圖 IIAbstract This paper system will be in J2ME flat, we use the JSR179 positioning and J2ME setups static map realize positioning, Google added interest points, route planning and offline map location etc. Function. In the mobile phone users to locate functional and J2ME hardware support for the case, as long as the users pay a small fee to the GPRS flow can be user location positioning, route planning etc. Function. In order to save the user of GPRS flow, design also developed offline map specific model, not connected to the Inter users can still for the GPS positioning.This paper will be divided into seven chapter was introduced. The first chapter the introduction, this paper introduces the background of the subject research, mobile GPS navigation development present situation and the main research topic in meaning and significance。 The second chapter to the article with the relevant technology of the system are introduced。 Chapter 3, 4, 5 in the key for this paper, this paper expounds the system demand, and the detailed design and the existing problem and so on。 The sixth chapter for the GPS phone prospect。 This paper is the seventh rules summary.【Key Words】 J2ME，MIDP，GPS ，JSR179 ， Google Static Map III目錄摘要 .................................................................................................................................................................IABSTRACT.......................................................................................................................................................II目錄 ...............................................................................................................................................................III引言 ...............................................................................................................................................................V第一章　 緒論 .................................................................................................................................................1 課題研究背景 ............................................................................................................................................1 手機 GPS 導航發(fā)展現(xiàn)狀 ............................................................................................................................1 課題主要內(nèi)容和意義 ................................................................................................................................2第二章　 相關(guān)技術(shù)概覽 ..................................................................................................................................4 基于位置的服務(wù) ........................................................................................................................................4 基于位置服務(wù)的應用范圍 ................................................................................................................4 基于位置服務(wù)的定位方法 ................................................................................................................4 移動地理信息系統(tǒng) ....................................................................................................................................6 J2ME 簡介 ...................................................................................................................................................7 J2ME 架構(gòu) ..........................................................................................................................................7 JVM ( 虛擬機 ) .................................................................................................................................8 MIDP( 移動信息設(shè)備簡表 ).............................................................................................................8 JSR179 開發(fā)包 ............................................................................................................................................9 GOOGLE API 簡介 .......................................................................................................................................10 路徑規(guī)劃的技術(shù)選擇 ..............................................................................................................................10 A 算法實現(xiàn)最短路徑搜索 ...............................................................................................................10 Google Directions API 提供服務(wù) ......................................................................................................11 路線規(guī)劃最終方法選擇 ..................................................................................................................12第三章　 軟件需求分析 ................................................................................................................................13 用戶需求 ..................................................................................................................................................13 功能模塊劃分 ..........................................................................................................................................13 功能模塊圖 ......................................................................................................................................14 功能要求 ..........................................................................................................................................14第四章　 詳細設(shè)計與開發(fā) ............................................................................................................................16 MIDLET 開發(fā)流程介紹 .............
