20203.網(wǎng)絡(luò)版測量數(shù)據(jù)處理系統(tǒng)的研究與應(yīng)用

1、論文題目：網(wǎng)絡(luò)版測量數(shù)據(jù)處理系統(tǒng)的研究與應(yīng)用專業(yè)：地圖制圖學(xué)與地理信息工程碩士生：陳曉娣（簽名）指導(dǎo)教師：胡榮明（簽名）摘要測量工作滲透在國家建設(shè)的諸多領(lǐng)域，測量數(shù)據(jù)處理作為其核心內(nèi)容顯得尤為重要。當(dāng)前，測量數(shù)據(jù)處理軟件已得到廣泛應(yīng)用，保證了測量計(jì)算的準(zhǔn)確性，不僅為工程設(shè)計(jì)、施工和安全運(yùn)營提供了可靠保證，還大大提高了工作效率。但是已有的軟件均為單機(jī)版，隨著網(wǎng)絡(luò)技術(shù)的飛速發(fā)展，開發(fā)測量數(shù)據(jù)處理的網(wǎng)絡(luò)平臺(tái)成為一個(gè)新的發(fā)展方向。為此本文進(jìn)行了

2、網(wǎng)絡(luò)版測量數(shù)據(jù)處理系統(tǒng)的研究與應(yīng)用。首先，指出傳統(tǒng)Web技術(shù)在系統(tǒng)研發(fā)中存在不足，而RIA則能很好地解決此問題。通過比較分析當(dāng)前幾種主流的RIA技術(shù)，從各自的技術(shù)特點(diǎn)、優(yōu)勢及掌握的難易程度等出發(fā)，選擇Silverlight作為實(shí)現(xiàn)網(wǎng)絡(luò)化的關(guān)鍵技術(shù)，并對(duì)Silverlight的技術(shù)架構(gòu)、界面模型、數(shù)據(jù)模型以及數(shù)據(jù)訪問和網(wǎng)絡(luò)通信技術(shù)進(jìn)行了深入研究。其次，介紹了系統(tǒng)研發(fā)所使用的測量數(shù)據(jù)處理的數(shù)學(xué)模型，主要有間接平差模型、秩虧網(wǎng)平差模型、粗差探

3、測方法、坐標(biāo)轉(zhuǎn)換以及圖幅計(jì)算等。然后，在確定了系統(tǒng)實(shí)現(xiàn)技術(shù)和數(shù)學(xué)模型的基礎(chǔ)上，選擇合適的系統(tǒng)開發(fā)平臺(tái)并對(duì)系統(tǒng)的功能、數(shù)據(jù)庫及數(shù)據(jù)輸入輸出方式進(jìn)行設(shè)計(jì)。其中平差算法程序設(shè)計(jì)、控制網(wǎng)圖形顯示、誤差橢圓的繪制以及BingMaps地圖服務(wù)二次開發(fā)是研究的難點(diǎn)和重點(diǎn)。最后，將所研發(fā)的系統(tǒng)應(yīng)用到具體工程項(xiàng)目中，并與常用軟件的處理結(jié)果進(jìn)行比較，驗(yàn)證系統(tǒng)數(shù)據(jù)處理的可靠性。關(guān)鍵詞：網(wǎng)絡(luò)化；測量數(shù)據(jù)處理系統(tǒng)；RIA；Silverlight；BingMaps
