遥感本身包含着非常广泛的科学技术领域,即传感器系统、数据收集装置、信息理论、数据处理的方法和装置、通讯理论和通讯机械,人造卫星和飞机等传感器运载设备,而且还必须具备能综合和利用上述的巨大系统理论和技术。同时,遥感的应用范围也是极广泛的,而且怎样理解遥感技术及其意义,实际上随每个人对遥感的立场的不同而有相当的差异。但是,将遥感作为以影像来表示物体表面电磁波辐射强度的方式来解释这一点是一致的。 Remote sensing itself encompasses a very wide range of scientific and technical fields, namely sensor systems, data collection devices, information theory, data processing methods and devices, communication theory and communications equipment, satellite and aircraft and other sensor delivery equipment, but also must have a comprehensive And make use of the huge system theory and techniques described above. At the same time, the range of application of remote sensing is also very wide, and how to understand remote sensing technology and its significance actually varies considerably with each person’s position on remote sensing. However, it is consistent that remote sensing is explained as a way of representing the intensity of electromagnetic radiation on the surface of an object.
