Résumé : The presentation shows using Erdas Imagine software for processing remote sensing data with a case study of Landsa TM images classified to detected land cover types in Aegean region, west Turkey. Two images were processed using Erdas Imageine, classified and changes in landscapes compared. The functionality of the 'connect to Google Earth' was activated in Erdas Imagine menu that enabled to visualize the same region of the current study on the Google Earth in a simultaneous way with Landsat TM. The selected areas with the most diverse landscape structure and high heterogeneity of the land cover types, have been verified by the overlapping of the Google Earth aerial images. Current paper has a technical contribution towards GIS/RS data processing, methods and algorithms. The presentation is demonstrated at Voronezh State University, Russia, 2015.
