Just try the feeling of looking at the Earth from space. The satellite maps present the Earth in true colours (blue water, green or yellow vegetation, white ice). These colour gradations allow you to see a lot of geographic details (highways, great airports and ports, big cities on the regional maps). The American civil Earth observation satellite Landsat 5 orbits the Earth since March 1984 with a speed of 27.000 km/h at an altitude of 705,3 km. The Landsat system catalogues a global coverage of the world‘s landmass, imaging the same 185 km ground swath every 16 days. The engineers of Planet Observer process then those datas in three steps 1) Removing the geometric distortions based on earth curvature and differences of altitude and remaping the image to a regular grid in a standard map projection 2) Adjusting the colour, especially the blue colouring due to the density of the atmospheric stratum 3) Assembling the images to a homogeneous mosaic, in order to cover large territories, ranging from a region up to the whole planet.

Set up in 1989 in Clermont-Ferrand (France), the company Planet Observer specializes from the very beginning in satellite imagery processing and in the production of true natural colour imagery mosaics covering large territories, a totally innovative concept at the end of the 80’s. Planet Observer has then developed « Terra Cognita », the first global natural colour satellite imagery mosaic composed of 8600 satellite images, totally homogeneous, georeferenced and orthorectified.
