随着空间时代的到来,美国的工艺和遥感技术于1960年代初期有了飞跃发展。由麦卡利、哥米尼、阿波罗载人飞船所拍摄的照片,提高了人们将遥感技术应用于森林经营的兴趣。于是,国家航空航天局(NASA)主办了三个遥感在林业中应用的计划:陆地卫星、天空实验室、地球资源调查计划。陆地卫星陆地卫星又称地球资源技术卫星,它是将专门研究地球资源的实验卫星射入轨道的第一 With the advent of the space age, the craft and remote sensing technology in the United States developed rapidly in the early 1960s. Photographs taken by the McCalley, Gamini and Apollo manned spacecraft have raised interest in using remote sensing technology in forest management. As a result, NASA hosted three remote sensing applications in forestry: land satellites, sky labs, and earth resource surveys.
