遥感是本世纪六十年代蓬勃发展起来的一门新兴的、综合性的探测技术,至今不过十余年,已引起世界各国许多领域和部门的重视,显示了强大的生命力。一、遥感的概念大家知道,地球上的各种物体,由于它们的化学组成和物理特性的不同,吸收、反射和辐射电磁波谱各频段的强度不一,因而表现了不同的颜色、温度和特性。平常人们通过五官感觉来获取各种物体发出的光谱讯号,来识别物体的存在。遥感则是从遥远的地方,运用仪器代替人的五官捕捉物体发出的光谱讯号,来识别不同物体。所以遥感技术实质上就是延伸
Remote Sensing is a new and comprehensive exploration technology booming in the 1960s. However, for more than ten years now, remote sensing has attracted the attention of many fields and departments of various countries in the world and demonstrated its great vitality. I. THE CONCEPT OF REMOTE SENSING Everyone knows that the various objects on the earth, due to their different chemical compositions and physical characteristics, have different intensities of absorption, reflection and radiation in all frequency bands of the electromagnetic spectrum and hence show different colors, temperatures and characteristics . Normal people through the senses to get the feeling of various objects issued by the spectral signal to identify the existence of objects. Remote sensing is from far away, the use of equipment instead of human facial features to capture the spectral signals emitted by objects, to identify different objects. Therefore, remote sensing technology is essentially an extension
