ABSTRACT
ABSTRACT: In the frame of the “Urban Geology” project of the Institute of Geology and Mineral Exploration (IGME) there is a need for accurate and up-to-date high resolution satellite data for the prefectures’ capital cities. Those data are used for land use classification, land cover change detection and urban area mapping. In order to ameliorate the spatial resolution of the satellite data six different techniques for the fusion of Ikonos and Quickbird multispectral data with the respective panchromatic data were used. Two different cities with complex physiography (Drama and Nafplio) were selected for the comparison of the efficiency of the techniques. Drama combines at the same time the characteristics of an urban and a rural area with high relief. Nafplio combines the characteristics of an urban and a coastal area.
