【摘要】:全球范圍內(nèi)海洋的覆蓋率達到2/3之上,其蘊藏著豐富的資源,對海洋資源的開發(fā)是目前各國最為重要和迫切的任務(wù)?茖W合理利用海洋資源是解決資源匱乏、環(huán)境惡化、人口膨脹的有效途徑。海洋環(huán)境監(jiān)測的手段非常的復雜,而且成本很高,對于這些具有很高價值且來之不易的海洋環(huán)境監(jiān)測數(shù)據(jù),如何合理地使用這些數(shù)據(jù),成為了人們研究海洋環(huán)境時最重要的工作。最傳統(tǒng)的方法是將數(shù)據(jù)以文件或紙質(zhì)資料的形式保存起來,相關(guān)的專家人工地選擇需要的數(shù)據(jù),人工繪圖分析數(shù)據(jù);隨著計算機的應(yīng)用,監(jiān)測數(shù)據(jù)被保存在數(shù)據(jù)庫中,然后利用專門的繪圖軟件繪制可視化的分析圖。以上兩種數(shù)據(jù)管理方式的效率相對較低,導致監(jiān)測數(shù)據(jù)的利用率很低,不能用于綜合的分析。目前隨著GIS技術(shù)的快速發(fā)展,利用GIS技術(shù)對監(jiān)測數(shù)據(jù)進行數(shù)據(jù)管理和可視化的分析,能夠提高海洋環(huán)境監(jiān)測數(shù)據(jù)的使用率。 本文深入地研究了GIS在海洋環(huán)境監(jiān)測數(shù)據(jù)可視化中的應(yīng)用,并研發(fā)了“基于GIS的海洋環(huán)境監(jiān)測數(shù)據(jù)可視化平臺”。根據(jù)海洋環(huán)境監(jiān)測數(shù)據(jù)的異構(gòu)性特點,通過合理的時空數(shù)據(jù)的建模,對海洋環(huán)境監(jiān)測數(shù)據(jù)進行統(tǒng)計分析,最后利用GIS對海洋環(huán)境監(jiān)測數(shù)據(jù)進行可視化的展示。本文的主要研究內(nèi)容如下: (1)研究海洋環(huán)境監(jiān)測數(shù)據(jù)的處理方法和步驟。 (2)研究海洋環(huán)境監(jiān)測數(shù)據(jù)的特點,選擇不同的分析模型進行分析。 (3)海量的海洋環(huán)境監(jiān)測數(shù)據(jù)的多元化可視化的實現(xiàn)。
[Abstract]:The global coverage of the ocean is above 2/3, which contains rich resources. The development of marine resources is the most important and urgent task in all countries. The scientific and rational use of marine resources is an effective way to solve the shortage of resources, the deterioration of the environment, and the expansion of the population. The means of marine environmental monitoring are very complex and cost very much. High, for these high value and hard won marine environment monitoring data, how to reasonably use these data has become the most important work for people to study the marine environment. The most traditional method is to save the data in the form of file or paper material. With the application of the computer, the monitoring data are stored in the database, and then the visual analysis chart is drawn with the special drawing software. The efficiency of the two data management methods is relatively low, which leads to the low utilization of the monitoring data and can not be used for the analysis of comprehensive integration. At present, with the rapid development of the GIS technology, the benefit of the analysis is very low. Using GIS technology for data management and visualization analysis of monitoring data can improve the utilization rate of marine environmental monitoring data.
This paper studies the application of GIS in the visualization of marine environmental monitoring data, and develops a "GIS based visualization platform for marine environmental monitoring data". According to the heterogeneity of marine environmental monitoring data, the statistical analysis of marine environment monitoring data is carried out by reasonable spatio-temporal data modeling, and the GIS is used to the sea at the end. The main contents of this paper are as follows:
(1) study the methods and steps of marine environmental monitoring data processing.
(2) study the characteristics of marine environmental monitoring data and select different analytical models for analysis.
(3) the realization of diversified visualization of massive marine environmental monitoring data.
