Ground sensing meaning
WebThe Landsat 8 satellite payload consists of two science instruments—the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). These two sensors provide seasonal coverage of the global landmass at a spatial resolution of 30 meters (visible, NIR, SWIR); 100 meters (thermal); and 15 meters (panchromatic). WebMay 24, 2024 · The calculation of GSD uses the focal length (FL in figure below) and sensor array dimensions, which are properties of the sensor, as well as the distance between the sensor and the ground at the moment of image capture (D in figure below), normally represented by the altitude of an aircraft or orbital distance of a satellite.
