Modifying the geometry of an image, which may be from either a remotely sensed or map data source. This process usually involves rectification and/or registration.
A measure of the amount of detail that can be seen in an image; i.e. the size of the smallest object recognisable using the detector.
In remotely sensed imagery, resolution is significant in four measurement dimensions: spectral, spatial, radiometric and temporal.
Satellite azimuth (degrees)
The angle of the satellite’s position from true north; i.e. the angle between true north and a vertical circle passing through the satellite and the point being imaged on Earth.
Satellite view or satellite zenith (degrees)
The angle between the zenith and the satellite.
The intensity of a colour. A highly saturated colour is vivid and brilliant. To dull a colour and decrease its saturation, add small amounts of its complement, making it closer to grey.
Each Landsat image collected is a scene. Each Landsat scene is 115x106 miles long. The globe is divided into 57,784 scenes, and each Landsat scene has about 3 billion bytes of data.
Sea and Land Surface Temperature Radiometer (SLSTR)
The Sea and Land Surface Temperature Radiometer (SLSTR) is a dual-view scanning temperature radiometer, which flies in low Earth orbit (800 - 830 km altitude). The principal objective of SLSTR products is to provide global and regional Sea and Land Surface Temperature (SST, LST) to a very high level of accuracy (better than 0.3 K for SST) for both climatological and meteorological applications.
