簡介：摘要摘要在信息時代全面來臨的今天，信息已經(jīng)成為重要資源和競爭資本。但隨著社會信息量的爆炸式增長，只有經(jīng)過針對性采集和系統(tǒng)化整理的信息才有意義，才能轉(zhuǎn)化成各類信息產(chǎn)品為人所用，從而創(chuàng)造經(jīng)濟價值。而縱觀現(xiàn)今，雜亂及錯誤的公交及地理信息仍處于“不可用”的狀態(tài)。在此基礎(chǔ)上開發(fā)的本公交換乘及地理信息系統(tǒng)定位于“基于位置信息分類標注的服務(wù)網(wǎng)絡(luò)平臺”，正實現(xiàn)了從原始信息到高價值信息產(chǎn)品的增值過程，是對龐雜的信息進行系統(tǒng)加工和深度挖掘的專業(yè)化平臺。在研發(fā)過程中，解決了信息采集、整理、加工、發(fā)布全過程中的流程控制、數(shù)據(jù)流管理、標準制定、平臺遷移、人機交互等難題。本文共分為三個部分。第一部分介紹了項目及市場同類產(chǎn)品狀況的背景知識。第二部分是本文的重點，對系統(tǒng)進行了需求分析及設(shè)計，尤其針對產(chǎn)品的數(shù)據(jù)采集、信息發(fā)布的細節(jié)作了更為周密的詳細設(shè)計。系統(tǒng)堅持模塊化設(shè)計，將整個系統(tǒng)根據(jù)業(yè)務(wù)分為數(shù)據(jù)平臺、服務(wù)平臺、應(yīng)用平臺三個子系統(tǒng)，按功能分為數(shù)據(jù)收集、數(shù)據(jù)挖掘、增值服務(wù)中間件、終端應(yīng)用、圖形引擎幾大模塊。使得這套系統(tǒng)可適應(yīng)多領(lǐng)域應(yīng)用，并實現(xiàn)最大的通用性和最小的二次開發(fā)代價。第三部分強調(diào)了系統(tǒng)的實現(xiàn)所采用的關(guān)鍵技術(shù)和展望。關(guān)鍵詞地理信息，基于位置信息分類標注，增值南開大學學位論文版權(quán)使用授權(quán)書南開大學學位論文版權(quán)使用授權(quán)書本人完全了解南開大學關(guān)于收集、保存、使用學位論文的規(guī)定，同意如下各項內(nèi)容按照學校要求提交學位論文的印刷本和電子版本學校有權(quán)保存學位論文的印刷本和電子版，并采用影印、縮印、掃描、數(shù)字化或其它手段保存論文學校有權(quán)提供目錄檢索以及提供本學位論文全文或者部分的閱覽服務(wù)學校有權(quán)按有關(guān)規(guī)定向國家有關(guān)部門或者機構(gòu)送交論文的復(fù)印件和電子版在不以贏利為目的的前提下，學?？梢赃m當復(fù)制論文的部分或全部內(nèi)容用于學術(shù)活動。學位論文作者簽名年月日經(jīng)指導教師同意，本學位論文屬于保密，在年解密后適用本授權(quán)書。指導教師簽名學位論文作者簽名解密時間年月日各密級的最長保密年限及書寫格式規(guī)定如下F17靚。FI鮮呼沐可I邢年紅裴10TLA1IF,墨F10F17LW20}FRT20,7F201F
