terravision : technical analysis and it's application in building global massive spatial data management system 技術(shù)分析及其在全球海量空間數(shù)據(jù)管理中的應(yīng)用
the system have powerful ability of spatial data management computation and analysis 使應(yīng)用軟件不僅具有強(qiáng)大的空間數(shù)據(jù)管理功能,而且還具有強(qiáng)大計(jì)算和分析功能。
80 percent or above of the system data has its spatial property, moreover the application of the spatial data management is very popular 80%以上的數(shù)據(jù)都具有空間屬性,而對(duì)這些空間數(shù)據(jù)的管理已經(jīng)應(yīng)用十分廣泛。
the author models a new type spatial data for dm3, and based on the model, enlarges dm3 action on spatial data management 隨后,本課題借助現(xiàn)有成熟的空間數(shù)據(jù)庫(kù)技術(shù)成果,針對(duì)國(guó)產(chǎn)數(shù)據(jù)庫(kù)dm3特點(diǎn)提出了提出基于dm3的空間數(shù)據(jù)庫(kù)解決方案。
