Vegetation cover in urban areas is changing rapidly, due to the decline in the share of green areas, cities are less suitable for living. Population growth and urbanization contribute to increased air pollution and global warming, so the in the thesis, we will observe the relationship between green and built-up areas in Skopje, a city that has experienced great urbanization and migration, and is one of the most polluted cities in the world in recent years. The aim of the task is to calculate, analyze and display changes in the vegetation and built-up area of the city in the period from 1993 to 2021 based on NDVI (normalized difference vegetation index) and NDBI (normalized difference built-up index) based on Landsat data. Part of the methodology is the determination of the border of built-up and green areas for a more detailed analysis. Individual municipalities that experienced the greatest growth in population and built-up area are analyzed. The vegetation index NDVI performs better in classification. The results are displayed with tables and charts and graphically on maps. We found changes in green areas in built-up areas, which was initially expected.
