贵州森林覆盖率达到30.1%,且多集中于地形复杂、山高坡陡、交通不便的山区,增加了林区火情监测和火点定位的难度。在应用NOAA卫星遥感监测森林火险业务中,利用G IS中M apOb jects的地理信息功能开发系统,可准确对贵州省的1 500多个乡镇进行火点精确定位。RS与G IS技术结合提高定位精度、缩短监测产品制作时间、提高服务的及时性。 Guizhou forest coverage rate reached 30.1%, and more concentrated in the complex terrain, steep mountain slopes, inconvenient traffic in the mountains, increasing the difficulty of forest fire monitoring and fire location. In the application of NOAA satellite remote sensing to monitor the forest fire insurance business, the Geographic Information Function Development System (MIPObjects) in G IS can be used to accurately locate fire spots in more than 1,500 towns in Guizhou Province. RS and G IS technology combine to improve the positioning accuracy, shorten the production time of monitoring products and improve the timeliness of service.
