Document Summary
Ersc 3p07 lecture 2: the remote-sensing process, digital data. Tone/colour, size, shape, texture, site (location), association. Rs sensor is onboard an rs platform. Rs instrument collects data about an object, area, or phenomenon within the instantaneous- field-of-view (ifov) of the sensor system. It is not in direct physical contact with the object/area/ phenomenon. Used to measures differences in crop health and vigour in real time. Technology uses red and nir light to calculate. Not affected by clouds or the sun. For example: filename convention, acquisition date, time of acquisition, geographic coverage, projection information, name of sensor and platform, data format, percent cloud cover, any other data quality measurements. Expressed as an angle (in degrees or radians) Ifov: provides a measure of the spatial resolution of a remote-sensing system. sensor. Near-polar (sun synchronous): low altitude (~700 km) Geostationary: high altitude (~36,000 km); weather and communications satellites typically have these orbits. The remote-sensing process: problem definition, digital data acquisition.
