【摘要】:不同的海洋環(huán)境要素對(duì)象、數(shù)據(jù)文件格式及數(shù)據(jù)分辨率使得對(duì)異構(gòu)且離散的場(chǎng)數(shù)據(jù)訪問(wèn)和應(yīng)用受到了限制.設(shè)計(jì)了面向分片地圖的統(tǒng)一數(shù)據(jù)多級(jí)存儲(chǔ)組織架構(gòu),定義了適用于不同分片地圖對(duì)象的海洋場(chǎng)數(shù)據(jù)組織方式,提出了多分辨率格點(diǎn)場(chǎng)數(shù)據(jù)分層和分塊方法,并通過(guò)建立索引編碼,實(shí)現(xiàn)將多要素、多時(shí)次、多深度、多高度的海洋環(huán)境場(chǎng)數(shù)據(jù)按統(tǒng)一維度的小區(qū)塊存儲(chǔ)并管理于多級(jí)組織架構(gòu)中.該方法在海洋環(huán)境預(yù)報(bào)綜合信息服務(wù)平臺(tái)的應(yīng)用中有效支持了異構(gòu)場(chǎng)數(shù)據(jù)的整合、時(shí)空統(tǒng)計(jì)分析及可視化表達(dá)等.
[Abstract]:Different objects of marine environment, data file format and data resolution restrict the access and application of heterogeneous and discrete field data. In this paper, a multi-level storage structure of unified data for sliced maps is designed, and a method of multi-resolution grid field data stratification and partitioning is proposed, which is suitable for different slice map objects. The multi-element, multi-time, multi-depth, multi-height marine environmental field data are stored and managed in the multi-level organizational structure according to the unified dimension small blocks by establishing index coding. This method can effectively support the integration of heterogeneous field data, spatio-temporal statistical analysis and visual expression in the application of integrated information service platform for marine environmental prediction.
