Satellite image formation and preprocessing methods

This paper gives a conceptual and practical introduction to the field of satellite image formation and preprocessing. In particular, the process of satellite image generation is discussed going through each step of its lifecycle. A special explanatory emphasis is given to the process of remote sensing and further mapping and fusion of satellite imagery within acquired segments of electromagnetic spectrum. Moreover, methods of satellite imagery retrieval have been practically demonstrated. The satellite imagery data has been extracted from Sentinel 2 dataset and analyzed with Python language image processing libraries.
