| 摘 要： | 通过分析MODIS多光谱地表覆盖产品,证明MODIS本身具有精确识别包括5种森林在内的IGBP 17种地表类型的能力,完全可以满足识别森林火灾的实际需要.在此基础上提出基于MODIS地表覆盖的森林火点识别方法,探讨使用MODIS地表覆盖数据识别森林火灾的数据处理操作过程.应用该森林火点识别方法,MODIS实时广播接收站可以建立一套由MODIS火点侦测模块和MODIS森林火点识别模块构成的完全基于自身数据的森林火灾监测系统.5种森林地表整体平均识别误差为3.5%,可以满足卫星遥感森林火灾监测系统要求.

| Abstract: | The national land use GIS database is used to identify forest fires and determine the positions of fires during the crossing of NOAA satellites, but its cost is high and the database cannot be updated yearly. MODIS is very different from NOAA, has the ability to identify 17 types of land surface with its VIS NIR SWIR multi channel spectral bands (wavelength 400 to 2500 nm). By analyzing the MODIS land cover (LC) products, a new forest fire pixel identification method based on MODIS land IGBP types is devised, and its reliability is discussed. The total confidence of the forest fire identification based on MODIS LC is about 96.5%. A near real time forest fire detection and monitoring system is constructed with an operational MODIS direct broadcast station. |
