Remote sensing – meaning, description and approach
Remote sensing is a process of acquiring information about physical objects through imagery and variety of sensors. It is a measurement of the electromagnetic properties of the surface of this objects without actual contact with them. We collect the imagery with satellites, aircraft and drones, while sensors we place in the study area and if possible to cover it all.
We can use this approach in variety of cases. It is especially relevant for monitoring weather, environmental control, land cover classification and urban analysis. In all cases we use either GIS or some open source platform for data management and analysis.
