Remote sensing satellites

In satellite remote sensing of the earth, the sensors are looking through a layer of atmosphere separating the sensors from the earths surface being observed. Remote sensing is acquisition of information about an object without making physical contact with the object and thus in contrast to site observation. Remote sensing refers to the activities of recording/observing/perceiving (sensing) objects or events at far away (remote) places. In remote sensing, the sensors are not in direct contact with the objects or events being observed. The information needs a physical carrier to travel from the objects/events to the sensors through an intervening medium. The electromagnetic radiation is normally used as an information carrier in remote sensing. Sonar (sound navigation and ranging technology is used to collect measurements from the sea floor by collecting point or raster data derived from the strength and time of the acoustic return. The National Oceanic and Atmospheric Association (NOAA) uses single and multibeam sonar for numerous applications like mapping seafloor geology, field verifying other remotely sensed data sets, navigation, disaster recovery and salvage, and habitat
studies, among other uses.
