遥感技术,指的是从飞机、人造卫星等飞行器上搜集地面物品目标的电磁辐射信息,从而判别地球环境与资源的科学技术。现如今这种新型的科学技术已经被广泛的应用在对自然灾害的救灾与减灾中,不仅能在灾难到来之前做出预警,在遭受灾难时进行救援,还能在灾难过后进行总结与恢复等工作。本文将从遥感技术的定义与基本原理入手,深入的探究遥感技术在减灾与救灾工作中的应用与应用特点。
Remote sensing technology refers to the science and technology of distinguishing the earth’s environment and resources from the electromagnetic radiation information of the targets of ground objects collected from aircraft such as aircraft and satellite. Now this new type of science and technology has been widely used in disaster relief and mitigation of natural disasters, not only in the disaster before the early warning, in the event of disaster relief, but also in the disaster after the summary and recovery, etc. jobs. This article will start with the definition and basic principle of remote sensing technology and deeply explore the application and application characteristics of remote sensing technology in disaster reduction and relief work.
