Abstract

In this study eight commercial available fusion techniques and more especially the Ehlers, High Pass Filter, HCS (Hyperspherical Color Space), Modified IHS (ModIHS), Pansharp, Pansharp2, PCA, and Wavelet were used for the fusion of a Declassified KH-7 airphoto and a Landsat1 MSS image. Both images were acquired on 1972. The panchromatic data have a spatial resolution of 8m while the multispectral data have a spatial resolution of 80m. The optical result, the statistical parameters and different quality indexes such as ERGAS, Q, entropy were examined and the results are presented. As the ultimate purpose of the data fusion is to help in the detection of old landslides, two small areas where historical landslides have been occurred were selected for the evaluation of the fusion algorithms. Both areas are located in western Peloponnese in Achaia Prefecture.
