Remote sensing is all about gathering information on the earth using techniques that are ‘at a distance’ rather than touching the earth. Generally speaking remote sensing produces either point cloud data or imagery. The data is further processed using [geographical information systems] as part of [cartography].

Often Remote Sensing is differentiated by the type of platform or sensor used. Platforms can range from satellites through aircraft and drones to cars and ships. From a sensor perspective, Remote Sensing is a broad field that encompasses techniques such as [photogrammetry] and [lidar] but also [echosounding]. Often a form of ground truthing is required to transform the Remotely Sensed data into comprehensible products.
