摘要
利用VIIRS SDR数据,基于火点像元亮温特征及其与背景亮温的偏差来提取秸秆焚烧火点信息。采用湖北省2015年秋收季节的VIIRS SDR 750 m分辨率下的第5、7、11波段反射率产品和13、15、16波段亮温值产品,基于VIIRS卫星影像秸秆焚烧火点监测算法和GIS平台叠加火点信息和地理基础数据生成湖北省秸秆焚烧火点分布图。结果表明,小火点检测率较高,漏检率降低。
Based on the characteristics of brightness temperature and the deviation from background brightness temperature, we used VIIRS SDR data to extract the fire point information of straw burning. And then, based on the VIIRS satellite image straw incineration fire point monitoring algorithm, GIS platform overlay Fire point information and the geographical basis data we used the 5 th, 7, 11 band reflectivity products and 13,15 and 16 bands of the VIIRS SDR 750 m resolution of the 2015 Autumn harvest season in Hubei Province to produce the Hubei Province straw incineration fire point distribution map. The results show that the detection rate of small fire point is higher and the rate of missing is lower.
