The mosaic is composed of images from Landsat 7 ETM with a spatial resolution of 30x30m per pixel.
The satellite sensor detects radiation from the surface of the earth in 7 discrete bands or channels, sensitive to different wavelength ranges of the light spectrum.
In this process the spectrum of visible light is bundled in three channels, red, green and blue, which are combined into a true colour, or RGB image.
Image requirements for the mosaic where a low cloud coverage and low tide level which is seldom congruent in one image.
The selection resulted in five images acquired in a range of three years between 2001 and 2003.
Phenological differences recorded between April and July are reflected by varieties in colours (see on the right above) and had to be taken into account for the image processing.
The images have been adjusted geographically and in colour before merging.
The final Mosaic (see on the right) extends approximately 410 km from North to South and 487 km from West to East, respectively 16260 x 13647 pixels.
