K. G. Nikolakopoulos, Using remote sensing multispectral data and GIS techniques for the geological mapping of Halki Island, Δελτίο της Ελληνικής Γεωλογικής Εταιρείας, 47|2013, 1500-1509

In this paper we present the combined use of remote sensing and GIS techniques for the geological mapping of Halki Island at 1/50.000 scale. The geological formations, geotectonic units and tectonic structures were recognized in situ and mapped. Interpretation  of  multispectral  satellite  images  (Landsat  TM  &  ETM  and  Terra ASTER) has been carried out in order to detect the linear or not structures of the study area. Different band ratio was also used in order to distinguish and map the limits of the different geotectonic units. The in situ mapping was enhanced with data derived from the digital processing of the satellite data. All the analogical and digital data were imported in a geodatabase specially designed for geological data. After the necessary topological control and corrections, the data were unified and processed in order to create the final map layout at 1/50.000 scale.
