随着航天技术的发展,各种人造卫星的成功发射和利用,遥感技术在农业中应用发展很快,范围不断扩大。美国专家列出了遥感技术在农业上分两大类5个领域。其一类是一般性应用,有土壤调查、水资源调查、土地利用制图等。第二类是特殊性应用,有农作物鉴定、农作物估产、森林火灾预警和侦察、病虫害侵袭调查等等。 With the development of aerospace technology, the successful launch and use of various satellites, the application of remote sensing technology in agriculture has developed rapidly, and the scope has expanded. U.S. experts have listed remote sensing technologies in agriculture in two major categories and five areas. The first category is general applications such as soil surveys, water resources surveys, and land use mapping. The second category is specific applications, including crop identification, crop estimation, forest fire warning and reconnaissance, and pest and disease intrusion investigations.
