The goal in this is to study the composition and structure of each framework. The emergency command information system of ocean oil spill is built on C⁴ISR (command, control, communication, computer, intelligence, surveillance and reconnaissance) architectural framework that is composed of command view, system view, and technology view. The physical framework of the command information system architecture is characterized by a multi-layer structure. The node is divided into LSP (local service peer), GSP (group service peer) and CSP (common service peer). Each system and software set can be encapsulated as part of the Ocean Oil Spill Information Services, with each service being capable of serving as a local service node. Furthermore, each local service node participates within a peer group. According to the service purpose and granularity, the functional framework is divided into physical resource layer, data layer, support service layer, application layer. Data layer mainly includes communication protocol, message format, data type, and various database, etc. Support service layer includes storage management service, information distribution service, service management, human-computer interactive service, resource sharing service and information security service, etc. Application layer includes situation generating service, emergency plan service, emergency command service, emergency assessment service, communication support service, navigation and positioning service, etc. We draw conclusions that the information system architecture proposed in the paper has more prominent reliability and flexibility through contrastive analysis of similar information system architecture, and lay foundations for research intoocean oil spill service-oriented command information systems.</p></div>","PeriodicalId":92478,"journal":{"name":"Aquatic procedia","volume":"3 ","pages":"Pages 41-49"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aqpro.2015.02.226","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138340200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hyperspectral remote sensing data can provide continuous spectrum, and be beneficial for the identification of oil film. The traditional detection method failed to make full use of different spectral characteristics of the oil film, so is unable to improving the identification precision of them. By deep digging the time-frequency information based on the wavelet transform, we can enhance the difference of the spectral characteristic between thick and thin oil film, so that we can find sensitive wavelength location of them. High frequency coefficient of wavelet transformation is able to indicating the sensitive spectral range of different thickness of oil film, and low frequency coefficient information is available for eliminating the noise of the image, consequently, enhancing the contrast between the categories. Based on this, this paper proposed a new method for classification of the various thickness of oil film based on wavelet transform spectrum information. Firstly, we extracted the sensitive wave bands of different thickness of oil film based on the analysis of the singularity of the high frequency wavelet coefficient curve. Secondly, we regenerated the new low-frequency wavelet coefficients image of sensitive bands which are regarded as sensitive bands in term of the analysis on the high frequency wavelet coefficients curve. Finally, we conducted the classification of the different thickness of oil spill film based on the new low-frequency wavelet coefficients image.
