摘要
卫星遥感是野火监测中的常规手段。通过比较各卫星遥感数据的光谱特性,提出日本的Himawari-8卫星作为新一代的静止轨道气象卫星,其高频率连续地观测数据能提供火灾动态演变的重要数据。新一代的极轨气象卫星Suomi NPP和Sentinel-3A具有相对高的时间分辨率和空间分辨率,可以提供火点发现、火点定位、燃烧面积测量、灾后评估等数据。中等分辨率(15~100m)的Landsat8能提供更精确的火点定位和更详细的地形信息。
Satellite remote sensing is routine in wildfires monitoring means. The paper proposed that as a new generation of geostationary satellite, the high frequency continuous observation data of our country＇s FY-4 satellite and Japanese＇s Himawari-8 satellite can provide important data of fire＇s dynamic evolution.The new generation of polar orbiting meteorological satellite Suomi NPP and Sentinel - 3a has relatively high spatial resolution and temporal resolution, can provide data for fire detection, fire location, burned area , post fire assessment.Landsat8 with medium resolution （15～100m）can provide more precise fire location and more detailed topographical information whitch would be utility for wildfire management activities.
