As China successfully launched the small satellite constellation-HJ-1 satellite, the first satellite to monitor and forecast environment and disaster which can acquire CCD multi-spectral images and HSI hyper-spectral images at the same time, the overall science and technology level to reduce disaster is markedly improved. Due to the distortions of the atmospheric absorption and scattering on the Solar-Target-Sensor...
In order to identify and assessment the disaster areas and changes of large-scale highway network rapidly after earthquake, a robust and high-efficiency damage assessment method and architecture for large-scale disaster of highway network through the combination of GIS and RS is proposed and experimented in this paper. According to the condition of the collection of satellite images, two solutions...
As the largest in-land fresh water lake of China, Poyang Lake is also an important wetland in the world. However, the lake area, like the other lake areas of China, has being faced series of ecological and environmental problems and challenges, such as soil erosion, land desertification, drought and flooding disasters, farmland being soiled, pollution, invasive species, loss of biodiversity, and more...
HJ-1A and HJ-1B, the first micro-satellite constellation for Environment and Disaster Monitoring of China, was successfully launched in China on September 6, 2008. The same multispectral imagers named HJ-1/CCD with four bands (R, G, B, Nir) and large swath are installed on both HJ-1A and HJ-1B. The HJ-1/CCD is the main sensor of the constellation. In this paper, data sets includes six image pairs...
The Wenchuan earthquake was a destructive earthquake that measured at 7.9 Mw occurred at 14:28:01.42 CST on May 12, 2008 in Sichuan province of China, which induced large quantities of secondary mountain disasters such as collapse, landslides, debris flows and barrier lakes. These disasters occurred and more seriously formed disaster chains causing great destruction, and costing many lives after both...
In recent years, with the occurrence of more and more natural disasters and emergencies, China has also been greatly affected by that without exception. Wireless communication technology is playing an important role in disaster and emergency management. In current applications, mobile communication network, as the main key technology, have been used to deal with disasters and emergencies. However,...
Since November 2009, China has suffered two successive rare weather processes: strong cold air has affected the northwest, north, northeast of china. Affected by the snow disaster, Beijing, Hebei, Shanxi and other 16 provinces suffered damage in varying degrees. There is tremendous impact on socio-economic development and people's lives. Therefore, there is an important signification and application...
Aiming at the increasingly serious pollution and ecological damage in mining cites, environmental information urgently are urgently needed to provide basis and decision-making for the economic transition of mining cites. This article describes main environmental problems existing in mining cites, as well as ways of monitoring these major environmental problems, such as the Landsat TM images are used...
In case of emergencies over large areas satellite remote sensing data can become a crucial source of information for disaster management and response allowing the recognition and assessment of damages to populated areas and traffic infrastructure, the identification of focus areas, and an efficient coordination of rescue actions. On 12 May 2008, an earthquake of approximately 8.0 Ms (according to...
Debris flows threaten human life security and property in its destroyed and buried way, especially dangerous to cities, which destroyed most seriously to the main structure-houses in the cities. This paper takes Dongchuan, a district of Kunming, Yunnan province as an example to explore the solution of estimating housing loss caused by urban debris flow disaster. Firstly, using spot-5 data to extract...
