Integration of Landsat and aeromagnetic data as aid to the structural analysis of Crete and S.E. Peloponessus

Abstract

Abstract The paper comments on the usefulness of remotely-sensed data (Land-sat MSS images in both digital and photographic format—aeromagnetic data) in the tectonic analysis of areas of Greece. The island of Crete was the main case study area, while a general analysis was also carried out in the South Eastern Peloponessus. Both image processing (spectral and spatial analysis) of the Landsat CCTs of Crete and computer analysis of the features mapped on the images have been carried out. Aeromagnetic data are also analysed using advanced processing techniques (spectral analysis and deconvolution). Structural interpretations are improved by the study of the enhanced Landsat images and aeromagnetic maps, while the use of the various computer techniques makes the analysis of the mapped patterns easier and more accurate. The combined interpretation of aeromagnetic and Landsat MSS data added several significant structural features, previously unrecognised from separate interpretations of aeromagnetic data and La...
