MODIS数据在森林火点识别中的应用研究

Study on Application of MODIS Data in Forest Fire Recognition

以昆明市安宁县和玉溪市易门县为研究区,选用MODIS数据作为数据源,ARCGIS和ENVI软件作为数据处理平台,采用绝对亮温、相对亮温和植被指数3个因子作为林火判断条件,提高林火判别的精度,为森林火灾的早期探测与发现、火灾扑救和损失评估业务在云南省的运用奠定基础。

Taking Anning County of Kunming City,Yimen County of Yuxi City as study area,selecting MODIS data as source,ARCGIS and ENVI as data processing platform,3 factors including absolute light temperature,relative light temperature and vegetation index were determined as conditions for forest fire detection.The method can improve the accuracy of identification of forest fires,lay the foundation for early detection and discovery of forest fires,fire fighting and damage assessment services in Yunnan Province.
