The procedure is divided into 4 steps: data preparation, data processing, information extraction and damage assessment, and contains three key targets which are damage information extraction, quantitative assessment and estimation of casualties and economic losses. In the first stage, the damage information of the buildings is the basis, and the other information, including building type, damage grade, built-over area, would be extracted by visual interpretation and automatically statistic with human-computer interaction from the high resolution disaster imageries. Then the remote sensing damage index and equivalent ground damage index of building could be counted in the second stage. According to this result, the specialists sketch a more exact intensity distribution in different regions of the metropolis. At last, the number of casualties is estimated by an empirical model adapting to worldwide earthquake as the detailed construction damage has been known. To assess the economic losses, we use a macro economic-based model which only needs population, per capita GDP and statistical macro-economic fragility related to seismic intensity. In this case, it is the first time to implement the methods of remote sensing assessment in foreign serious earthquake emergency, which is proven of being applicable outside China.","PeriodicalId":340728,"journal":{"name":"China Symposium on Remote Sensing","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127248776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The remote sensing geochemical anomalies over the areas extending towards south and northwest had been enclosed by analysing the geochemical surface sampling, surveying spectrum at corresponding points in field, determing spectrum characteristic spectral range and the threshold value of different element anomalies or different lithological section, as well as making line No.55 of remote sensing ,geology exploration and geochemical section as a benchmark. The study shows that the zones of remote sensing-geochemistry anomaly calculated by the statistical models consistent with the known mining areas, and there are traditional geochemical anomaly within the remote sensing geochemical anomaly in the parts of the unknown area, which is also validated by remote sensing geochemical anomalies distributed in periphery. By analyzing both remote sensing geochemical anomaly and regional geological data, the predictions achieve better effects than that by using the information of remote sensing and geochemical anomalies only.","PeriodicalId":340728,"journal":{"name":"China Symposium on Remote Sensing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128796241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper focuses on the role of environmental factors in spread and epidemic of seasonal influenza and explores the environmental explanatory factors for different types of influenza in mainland China. It also introduces satellite remote sensing as an important data obtaining approach, and highlights the potential of using satellite images for monitoring dynamics of climate and landscapes related to the spread of seasonal influenza. Applying Geographic Information System (GIS) technique combining with traditional statistical analysis, the paper uses influenza virus isolation rate (VIR) as the measure of influenza activity and analyzed its association with environmental factors. The results show that the spread and epidemic of influenza is influenced by various environmental factors, among which the temperature and humidity are seemed to be the determinants. However, the impacts of the environmental factors to different types of virus are varied. Low temperature and humidity conditions arere associated with a higher activity of both influenza A and B. On the contrary, high temperature and humidity conditions are associated with a higher activity of influenza A, but are associated with only a moderate or low, less consistent increase in the activity of influenza B. Recognition of this association could lead to better understanding of the mechanisms of emergence of influence epidemics and provide scientific evidence for controlling influenza.","PeriodicalId":340728,"journal":{"name":"China Symposium on Remote Sensing","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116911595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
