一、遥感技术的特点现代遥感主要是指电磁波遥感,即不直接与物体接触,而是运用现代化的运载工具和仪器,从高空或远处,通过接收、记录物体电磁波特征,对物体性质进行调查或测量。自然界的各种物体,由于组成它们的物质结构不同,所以它们发射、吸收电磁波的波长和频率也不一样,也就是不同物体的电磁波幅射特性不同。现代遥感技术正是利用物
I. Characteristics of Remote Sensing Technology Modern remote sensing mainly refers to the remote sensing of electromagnetic waves, that is, it does not directly contact with objects. Instead, it uses modern vehicles and instruments to survey the properties of objects from above or below by receiving and recording the electromagnetic characteristics of objects Or measure. Because of the different material structures of the various objects in nature, they emit and absorb electromagnetic waves in different wavelengths and frequencies, that is, the electromagnetic radiation characteristics of different objects are different. Modern remote sensing technology is the use of things
