“遥感”是地理学家Erelyn Pruitt首先建议,用以替代“航空摄影”这一术语。加拿大遥感中心曾提出一个解释:“遥感主要是研究地球表面物体的电磁波辐射、散射和反射的环境信息以及搜集、处理的显示技术并应用于资源勘探与生产管理。” “遥感”可分为狭义的理解与广义的概念。由于遥感技术发展水平与“大气窗口”的限制, “Remote Sensing ” was first proposed by geographer Erelyn Pruitt to replace the term “aerial photography.” The Canadian Remote Sensing Center has put forward an explanation: “Remote sensing is mainly about studying the environmental information of electromagnetic wave radiation, scattering and reflection on the surface of the Earth as well as the collection and processing of display technologies and their application to resource exploration and production management.” Can be divided into a narrow sense of understanding and generalized concept. Due to the development of remote sensing technology and “atmospheric window ” restrictions,
