This paper first analyzed the characteristics of relevant image classification methods based on the high spectral characteristics of the acquired airborne high spectral data, and then obtained the better airborne oil pollution classification image results of hyperspectral data through the research and using of spectral angle analysis method of image classification, which verified the feasibility of...
Marine environmental management needs automatic analysis of Marine environment monitoring data. According to the characteristics of Marine monitoring data, this paper introduces how to establish Marine environment monitoring data automatic analysis system by using computer and GIS technologies, the design and implementation of the system is also discussed. Automatic analysis of Marine environment...
Using 5 periods' remote sensing images covering 20 years from 1987 to 2008 of Tianjin city, this paper extracted the coastline and the wetlands from different years utilizing different methods and techniques of data image processing and visual interpretation based on the characteristic of each RS image. The paper analyzed the law of the coastline and the wetlands changes in both spatial and temporal...
Satellite remote sensing has been an important method of marine monitoring. In this paper, according to the requirements of marine monitoring and marine management, the authors produced figures to show the coastline changes, distributions of suspended sediment and chlorophyll-a based on the data from Landsat-5 and synchronous monitoring data of Yellow River's mouth and Laizhou Bay in different periods...
The rapid monitoring and warning technologies of red tide have been a hot topic research as red tide was one of global marine disasters. In this paper, the author described red tide rapid monitoring and warning technologies, then discussed the construction of rapid monitoring system. Article also described the rapid monitoring and warning system based GIS, which made great contribution of red tide's...
The coastal zone systems of Bohai Sea make a significant role in Bohai Sea region's economic development, which constitutes the Bohai economic circle support system. But with economic development, a series of pollution problems occur. This article points out Bohai Sea now has been seriously polluted and the pollution has already affected ecology. According to the present development, resources and...
In this paper, we used radiance-reflectance transformation method based on data character to get the reflectance of oil seawater since there is no atmosphere parameters measured. Furthermore, The characteristic spectrum of normal seawater and oil seawater are also analyzed and discussed, from which we drawn conclusions that the method can be used for obtaining reflectance data and aerial hyperspectral...
Geographic Information System (GIS)has a wide range of applications in many areas. The project "the Bohai Sea ecological environment real-time monitoring demonstration system" uses the ships which carries the fast observation system, the ecology buoyage, the submarine automatic inspection station, and other monitoring measures to carries on the monitoring to the Bohai Sea ecological environmental...
As red tide was one of global marine disasters, its monitoring and warning has been a hot topic research in recent years. In this paper, the author described red tide monitoring, warning, emergency disposal technologies, and discussed the construction of early warning system. The article described the warning system application in 2008 Qingdao Olympic sailing competition, providing an application...
