INVESTIGATION OF THE RELATIONSHIP BETWEEN ALBEDO, LAND SURFACE TEMPERATURE AND NDVI USING LANDSAT-7 AND LANDSAT-8 SATELLITE DATA: A CASE STUDY SAFRANBOLU
Abstract
Developing remote sensing technologies are effectively used in monitoring the changes in surface parameters in urban areas. Information about urban heat islands is obtained by utilizing the spectral and thermal properties of surfaces at local and global scale. In our study, Safranbolu district of Karabük province, which is on the World Cultural Heritage list, has been chosen as the application area. Landsat-7 satellite image data from 12/08/1999, and Landsat-8 satellite image data from 11/08/2019, were used to calculate the Albedo, Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) variables. In the results, it was determined that there were positive relations between LST and albedo, negative relations between LST and NDVI, and negative relations between albedo and NDVI. These relationships were found similarly in both correlation analysis and scatter plots. The main factors affecting the relationship between LST, albedo and NDVI can be listed as the type of material on the surface, the amount of moisture on the surface, vegetation and its density.
