This study aimed to analyze and characterize a protected area based on satellite imagery. Protected areas are terrestrial or aquatic areas specially designed to protect and maintain biodiversity, natural resources and related cultural resources. Remote sensing is the technology by which objects can be measured, identified and analyzed from a distance, without the need for direct contact. Thus, for the analysis of satellite images, we used the data obtained from Landsat 8. Semenic-Cheile Carasului National Park was studied under the aspect of the variation of NDVI, NDMI and NBR indices. It was considered a period of seven years, 2015-2022, for the study, and as the period of the year the summer season was taken into account. Satellite scenes, Landsat 8, were used, taken in August during the study period. Based on spectral information and established formulas, NDVI, NDMI and NBR indices were calculated. To better analyze the features in pictures, we use band combinations. We accomplish this by creatively rearranging the available channels. We can extract specific information from an image by employing band combinations. It can be seen how Semenic-Cheile Carasului changed its dynamics over the years.
