data n. 1.資料,材料〔此詞系 datum 的復(fù)數(shù)。但 datum 罕用,一般即以 data 作為集合詞,在口語(yǔ)中往往用單數(shù)動(dòng)詞;如系指一件資料,則說(shuō)作 this data〕。 2.〔美國(guó)〕(觀察所得的)事實(shí),知識(shí)。 a data book 參考資料書(shū)。 gather data on ...收集…的資料[數(shù)據(jù)]。 The data is not enough to be convincing. 資料不足,尚難令人信服。

Many of these applications will be run on intranets within businesses and government agencies as a means of distributing and using geospatial data 采用何種webgis技術(shù)以及如何將這些技術(shù)互相結(jié)合,來(lái)提高網(wǎng)絡(luò)信息發(fā)布的質(zhì)量和效率,目前尚有待進(jìn)一步研究。
Nascar , the nfl , professional hockey , and other sports apply real - time video effects , such as the colored first - down line in football , based on precise geospatial data Nascar 、 nfl 、職業(yè)冰球和其他運(yùn)動(dòng)都開(kāi)始應(yīng)用實(shí)時(shí)視頻效果,比如在橄欖球場(chǎng)上根據(jù)精確的位置數(shù)據(jù)給觸地得分區(qū)加顏色。
In the research and development of the vehicle monitoring system , we have solved how to store and manage the geospatial data . we use gml to transfer geographic information and use svg to view the geographic information , find a method of transformation from gml to svg 在車輛監(jiān)控系統(tǒng)的研究與開(kāi)發(fā)中,解決了空間地理數(shù)據(jù)的存儲(chǔ)和管理,應(yīng)用gml進(jìn)行空間地理數(shù)據(jù)的數(shù)據(jù)交換,用svg進(jìn)行空間數(shù)據(jù)的瀏覽,并給出了從gml數(shù)據(jù)到svg數(shù)據(jù)的轉(zhuǎn)換方法。
At present , geospatial data can be encoding into svg format . but it is not properly resolved that how to dynamic publish svg graphics from the spatial management engineer , realize the complex spatial analysis of svg vector graphics and the svg edit function of webgis 目前,可以將地理空間數(shù)據(jù)編碼成svg格式,但是如何基于空間數(shù)據(jù)管理產(chǎn)品動(dòng)態(tài)發(fā)布svg格式的矢量地圖,以及在此矢量地圖上實(shí)現(xiàn)復(fù)雜空間分析和圖形編輯,一直沒(méi)有得到很好的解決。
Thus html is disadvantage to describe the structural geospatial data and the implement of geospatial - data sharing . so we need the web language to effectively describe the geospatial data , and xml is the result . xml is to be the new web language , and it ' s the perfect medium to sharing and altering the geospatial - data 因此,傳統(tǒng)的web語(yǔ)言對(duì)復(fù)雜的空間信息的描述和表現(xiàn)具有先天的不足與缺陷,不利于實(shí)現(xiàn)webgis數(shù)據(jù)共享,從而需要一種新的web語(yǔ)言來(lái)有效地描述空間信息,實(shí)現(xiàn)更廣泛的空間信息的共享。
Webgis will make it possible to add gis function into a wide rahge of network - based applications in business , government , and education . many of these applications will be run on intranets within businesses and government agencies as a means of distributing and using geospatial data . the challenge of webgis lies in creating software systems which have platform independent and run on open tcp / ip - based networks Webgis在企業(yè)、政府、教育機(jī)構(gòu)等各行各業(yè)中得到廣泛使用,形成了這一領(lǐng)域的激烈競(jìng)爭(zhēng)的局而,各gis廠商可謂百家爭(zhēng)鳴、百花齊放,紛紛推出了自己的webgis產(chǎn)品,主要有esri公司的mapobiectims , intergraph公司的webmap , maplnfo公司的proserver , supermap公司的supermapis ,國(guó)家遙感應(yīng)用工程技術(shù)研究中心的geobeans等。
2 ) analyzes the advantages of gml in geospatial data sharing and interoperability , makes out a transitional solution based on the original " dark model " ; 3 ) goes deeply into the using of distributed computing technologies in webgis , discusses the advantages of developing webgis based on j2ee platform 2 )探討gml在解決webgis空間數(shù)據(jù)共享與互操作中的優(yōu)勢(shì),設(shè)計(jì)一種在原有“黑箱模型”基礎(chǔ)上的過(guò)渡型方案。 3 )深入分布式技術(shù)在webgis中的應(yīng)用,分析基于j2ee開(kāi)發(fā)webgis的優(yōu)勢(shì),基于webgis分步驟服務(wù)模型結(jié)合gml給出一種webgis的瀏覽器服務(wù)器分布式計(jì)算策略。
