A
- Atmospheric correction
- A pre-processing step for satellite imagery to remove atmospheric effects in order to enhance accuracy of surface reflectance.

- Pixel
- The smallest spatial unit in a digital image. A satellite image is made up of a matrix pixels, each having its own vector of digital values for each band.
R
- Radiometric resolution
- Sensitivity (maximum range of values) of the sensor in detecting different intensities of electromagnetic radiation in single spectral bands. Typically recorded in 6 bit, 7 bit, 8 bit, 10 bit or 16 bit format. The contrast of a raster image is depending on radiometric resolution.
S
- Spatial resolution
- The size of a pixel (corresponding ground area that is covered by a pixel) that is recorded in a raster image – typically pixels correspond to square areas.
