Özet:

In this study, it is aimed to determine the changes in land use between 1984-2022 in Pamukova (Sakarya) district by using Remote Sensing (UA) and Geographic Information Systems (GIS) techniques. For this purpose, 08.08.1984 Landsat TM and 24.07.2022 Landsat 8 (OLI/TIRS) satellite images were used in the study. After the satellite images were processed with the ArcGIS 10.8 program, land use maps for the years 1984 and 2022 were produced and the temporal change according to the years was determined quantitatively and spatially. While producing the land use map, first NDVI analysis and then controlled classification were performed on the satellite images. 5 different classes (forest areas, artificial areas, agricultural areas, water areas, sparse vegetation) were created from the image classified by applying the maximum similarity method. During the controlled classification process, Corine and Google Earth maps were also used in coordination while creating the reference points. For the accuracy analysis, 100 sampling points were randomly assigned to each class and the user and manufacturer accuracy was found by checking what these areas correspond to in the controlled classification and what they actually are. Then the Kappa index was calculated. As a result of the study, while the semi-natural areas, artificial areas and water surfaces gained area, forest areas and agricultural areas were included in the land class that lost area. At the end of the study, suggestions related to the dynamics of the region, planned, programmed, healthy and encouraging land use were made to protect the natural environment.
