遥感:就是用装载在飞机或人造卫星等运载工具上的探测仪器(如照相机、扫描仪等),接受目标物反射或发射的各种电磁波信息,并对这些信息进行加工处理,从而对不同的地物及其特性进行远距离的探测和识别,这个过程叫做遥感。遥感技术则是实现上述过程所采取的各种技术手段的总称。它包括:(1)传感器技术:专门研究感测目标特征信息和收集记录目标特征信息设备的技术;(2)信息传输技术:专门研究如何将传感器收集记录的信息传送到处理中心的技术:(3)信息处理、分析判读和应用技术:专门对遥感信息加工处理、研究分析和应用的技术;(3)遥感的理论基础研究:专门研究
Remote Sensing: It uses the detection instruments (such as cameras, scanners, etc.) loaded on vehicles such as aircraft or satellite to receive various electromagnetic wave information reflected or emitted by the target and process the information to process different information Objects and their characteristics for long-range detection and identification, the process is called remote sensing. Remote sensing technology is a general term for various technical means adopted to realize the above process. It includes: (1) sensor technology: a technology that specializes in sensing target characteristic information and collecting equipment for recording target characteristic information; (2) information transmission technology: technology that specifically studies how information collected by a sensor is transmitted to a processing center: 3) Information Processing, Analysis, Interpretation and Application Technology: Technology that specializes in the processing and processing of remote sensing information, research and analysis and application; (3) Theoretical basic research of remote sensing: specialized research
