Remote Sensing has a growing relevance in the modern information society. It represents a key technology as part of the aerospace industry and bears increasing economic relevance.
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation, especially the Earth.
Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring it’s reflected and emitted radiation at a distance (typically from satellite or aircraft).
Remote sensing makes it possible to collect data from dangerous or inaccessible areas. Remote sensing applications include monitoring deforestation.
Remote sensing also replaces costly and slow data collection on the ground, ensuring in the process that areas or objects are not disturbed.
Remote sensing data are processed and analyzed with computer software, known as a remote sensing application. A large number of proprietary and open-source applications exist to process remote sensing data.
Examples of applications of these data include population and demography studies, the study of archaeological sites, energy studies using hydrological models, urban planning, environmental treaty enforcement, and agricultural yields.
