Using freely available applications for satellite imagery processing in the preparation of specialists of the Geographic Service of the Czech Army

Satellite imagery forms one of the most important sources of information and data for obtaining knowledge about objects and phenomena that are present or taking place on the Earth's surface. In order to train the staff of the geographic service, it is necessary to master the methods of acquisition, processing, analysis and use of satellite imagery. Without this, it is not possible to meet demanding requirements within geospatial support, whether for training at home territory or in operations abroad. That is why so much attention is paid at the Faculty of Military Technology of the University of Defence and especially at the Department of Military Geography and Meteorology to the preparation of students in remote sensing and imagery processing. For this purpose, not only proprietary SW tools widely used in practice in facilities and departments of the Army of the Czech Republic are used, but also freely available applications that complement them appropriately. This article deals with the possibilities of freely available applications for processing satellite imagery and develops the EO Browser application as an example.
