Resolution

Satellite images are not all the same! In fact, they differ in many respects. Satellite images can be best described by taking a look at their resolution. In doing so, you have to distinguish between spatial, temporal and spectral resolutions.

Auflösung von Satellitenbildern

 

 

 

  The spectral resolution indicates how well a spectral-digital satellite sensor can distinguish between the different spectral ranges of the electromagnetic spectrum. The spectral resolution is characterised by the number of spectral bands.
  The spatial resolution signals the size of the section of the surface of the earth which can be depicted in one pixel. The spatial resolution is stated in metre.
  The temporal resolution indicates the distance of time between the single image acquisitions of the same area. The temporal resolution can be stated in minutes, hours or days.
