Shoman,W., Korkutan, M., Alganci, U., Tanik, A., Demirel, H.

Abstract: In this study, the changes in land cover/use is detected using remote sensing, GIS and stochastic modelling for part of metropolitan Istanbul city. The selected area has changed significantly in the last 40 years making it ideal case of study. The followed methodology is as follows. Firstly, five satellite imageries going back to 1975, 1987, 1997, 2007 and 2014 are acquired, rectified and classified to extract their land cover/use thematic maps. Level two of CORINE standards is implemented to acquire the relevant classes to the study i.e. urban fabric, industrial, commercial and transport units, mine, dump and construction sites, artificial non-agricultural vegetated areas, arable land, forests, shrubs, open spaces with little or no vegetation, inland wetlands, inland waters and marine waters. Secondly, raster thematic maps for all dates are converted to vector based maps to be implemented in GIS environment. Thirdly, statistics regarding each class are calculated for all dates. Finally, geostatistics approaches are applied to simulate the change in the future using the obtained historical data.
