Remote sensing describes all procedures to obtain information about the Earth’s surface by measuring and interpreting the waves emanating or reflected from it. Remote Sensing is thus an indirect, contactless observation method to obtain data about our Earth or its surface. During data acquisition, the electromagnetic radiation emitted or reflected by objects is received and stored by a sensor. Represented as images, the data can be delivered as aerial and satellite imagery.
Remote sensing data is particularly important in the various fields of geoscience (such as geomorphology), since a global observation of the earth’s surface and atmosphere in high spatial and temporal resolution is possible only with the help of remote sensing sensors.
