Analysis of temporal changes of light pollution of the Czech Republic during the last twenty years using satellite data.
 SOKOLÍK, Jakub
This thesis deals with the problem of light pollution. In the theoretical part it brings description of the types of light pollution, effects on organisms, information about remote sensing and characteristics of satellites which are used to map light pollution. Time composition images from DMSP satellites (F10-F18) are processed in the practical part. Changes in light intensity for the period 1992 to 2013 are described using these images. During visual assessment the most noticeable changes were obvious when comparing 1992 and 2013, when significant growth of light pollution was especially visible around cities. Statistical evaluation showed increasing values in the categories which contain higher DN (digital number) value. This increase also represents a shift to a higher light intensity level. The results suggest that light pollution in the Czech Republic tends to grow.
