Secondly , apart from the spatial character , the operational data of sea area use management are characterized by multi - source , multiple scale , and coordinate , complex type and large quantity , etc , so this paper has laid emphasis on studying the spatial data model and the data framework related to the management of sea area use , solved a series of key technical problems such as check and correction , organization and structrue , quality management and standard norms for the geographical sapce data associated with the management of sea area use , proposed various practical and effective ways of storing and managing spatial and non - spatial data and established the spatial data base system for the management of sea area use 其次,由于海域使用管理業(yè)務(wù)數(shù)據(jù)除空間特性外,還具有多源、多尺度、多坐標(biāo)、類型復(fù)雜、數(shù)據(jù)量大等特征,因此,本文重點研究了與海域使用管理相關(guān)的空間數(shù)據(jù)模型與數(shù)據(jù)框架,解決了海域使用管理相關(guān)地理空間數(shù)據(jù)的復(fù)合與訂正、組織與結(jié)構(gòu)、質(zhì)量管理與標(biāo)準(zhǔn)規(guī)范等一系列關(guān)鍵技術(shù)問題,并提出了切實有效的空間數(shù)據(jù)和非空間數(shù)據(jù)的不同的存儲、管理方式,建立了海域使用管理空間數(shù)據(jù)庫系統(tǒng)。
We research how to construct a spatial data model on oracle spatial ( database ) , and then construct our object - oriented spatial data model . we provide a webgis system which introduce the technology of j2ee , distribute componet , muti - layer and oracle spatial data storage ; the user can use it with vector spatial data 本文從理論上研究和探討了基于oraclespatial (簡稱spatial ) ,怎樣建立空間數(shù)據(jù)模型,在所建立的空間數(shù)據(jù)模型基礎(chǔ)上,構(gòu)建適合于webgis應(yīng)用環(huán)境,為用戶提供矢量空間數(shù)據(jù)操縱并滿足用戶需求的分布式組件化webgis系統(tǒng)。
