应用卫星遥感技术提高森林防火救火现代化水平是近年迅速发展的新领域,许多国家都十分重视,并已取得可喜成效。但至今许多人只注意到气象卫星高分辨辐射计(简称AVHRR)的作用,尚不了解陆地卫星专题成象仪(简称TM)的应用价值。一、气象卫星用于林火监测的优越性与局限性气象卫星AVHRR图象用于林火监测的优越性是显而易见的。每张图象的覆盖范围广,重复观测的周期短。现仍在作业的气象卫星NOAA—9,NOAA—10两颗卫星每
The application of satellite remote sensing technology to improve the level of modernization of forest fire prevention and fire fighting is a new area that has witnessed rapid development in recent years. Many countries attach great importance to this and have achieved gratifying results. However, so far many people have only noticed the role of high-resolution meteorological satellites (referred to as AVHRR) and have not yet understood the value of Landsat Special Purpose Imager (TM). First, the advantages and limitations of meteorological satellites for forest fire monitoring The advantages of meteorological satellite AVHRR images for forest fire monitoring are obvious. The coverage of each image is wide and the period of repeated observation is short. Currently operating meteorological satellites NOAA-9, NOAA-10 two satellites each
