    • 簡介:摘要摘要在信息時(shí)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(huì)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(jì)價(jià)值。而縱觀現(xiàn)今,雜亂及錯(cuò)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(biāo)注的服務(wù)網(wǎng)絡(luò)平臺”,正實(shí)現(xiàn)了從原始信息到高價(jià)值信息產(chǎn)品的增值過程,是對龐雜的信息進(jìn)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(biāo)準(zhǔn)制定、平臺遷移、人機(jī)交互等難題。本文共分為三個(gè)部分。第一部分介紹了項(xiàng)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(diǎn),對系統(tǒng)進(jìn)行了需求分析及設(shè)計(jì),尤其針對產(chǎn)品的數(shù)據(jù)采集、信息發(fā)布的細(xì)節(jié)作了更為周密的詳細(xì)設(shè)計(jì)。系統(tǒng)堅(jiān)持模塊化設(shè)計(jì),將整個(gè)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(gè)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(shí)現(xiàn)最大的通用性和最小的二次開發(fā)代價(jià)。第三部分強(qiáng)調(diào)了系統(tǒng)的實(shí)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(biāo)注,增值南開大學(xué)學(xué)位論文版權(quán)使用授權(quán)書南開大學(xué)學(xué)位論文版權(quán)使用授權(quán)書本人完全了解南開大學(xué)關(guān)于收集、保存、使用學(xué)位論文的規(guī)定,同意如下各項(xiàng)內(nèi)容按照學(xué)校要求提交學(xué)位論文的印刷本和電子版本學(xué)校有權(quán)保存學(xué)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(xué)校有權(quán)提供目錄檢索以及提供本學(xué)位論文全文或者部分的閱覽服務(wù)學(xué)校有權(quán)按有關(guān)規(guī)定向國家有關(guān)部門或者機(jī)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(xué)??梢赃m當(dāng)復(fù)制論文的部分或全部內(nèi)容用于學(xué)術(shù)活動(dòng)。學(xué)位論文作者簽名年月日經(jīng)指導(dǎo)教師同意,本學(xué)位論文屬于保密,在年解密后適用本授權(quán)書。指導(dǎo)教師簽名學(xué)位論文作者簽名解密時(shí)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
