摘要：The article presents methodology of processing and application of multitemporal satellite data for the monitoring of changes in selected environment elements in the Słowiński National Park. In the first stage of work,Landsat images from 1979 and 2000 were subjected to atmospheric correction,and then to the process of pixel resampling from 30 m to 60 m,and vice versa. LANDSAT images (UTM arrangement) were utilized for generating images: NDVI vegetation index. Based on the generated colour compositions in natural and pre-arranged colours,results of non-supervised classification,NDVI results,and analysis of orthophotomaps obtained from air images,there were seven classes of area coverage defined. Next,using the ENVI programme, supervised classification was conducted,and its results were used for the analysis of changes in the Park area coverage. Taking into account both the year,in which images were made and the size of pixels on area coverage maps,the percentage share of areas of particular classes was analysed. Based on the review of NDVI results,it was found that the dynamics of changes in the analysed period of twenty-one years is clearly visible in the case of the most active elements of the Park environment, that is migrating dunes. The analysis of area coverage maps from 1979 and 2000 revealed that noticeable changes took place as regards forests,whose percentage share was increased by 4-6% after 21 years.
