Determining the effect of urbanization on green spaces by NDVI analysis: Bilecik City example

Abstract

The acceleration of human activities on earth has caused positive or negative effects on the physical environment. These effects have become visible with the advancement of science and technology. Satellite images of Bilecik province used in this study, belonging to three different years, were obtained from Landsat 4-5 TM, Landsat 7 ETM and Landsat 8 OLI satellites. These satellite images were transferred to GIS software and NDVI vegetation analysis was performed. As a result of these analyzes, the parts with intense green color indicate that the vegetation is high, while the parts with the intense red color indicate that the vegetation is low and the settlement is high. The yellow color highlights the transition zone between these two parts. As a result of this analysis, the effect of urbanization on green areas was clearly observed.
