Spatial analysis of two different urban landscapes using satellite images and landscape metrics

Şimşek, D. and Sertel, E.

Abstract: This research aims to compare landscape metrics of two different cities having distinct landscape characteristics by using up-to-date, very high resolution SPOT 6/7 images-derived and thematically extensive urban land cover/use (LCLU) maps produced from object based classification approach. Object based classification method was applied to 1.5 m resolution SPOT images in conjunction with some opensource geoinformation in order to create accurate urban LCLU maps. Landscape metrics were calculated using detailed land cover/use classes and comparisons were conducted for two different city landscapes; one having huge industrialized areas and another with urban sites and archeological city residences which was declared as World Cultural Heritage. Patch Density (PD), Edge Density (ED), Largest Patch Index (LPI), Euclidean Nearest Neighbor Distance Distribution (ENN_MN), Area-Weighted Mean Fractal Dimension Index (FRAC_AM) and Contagion (CONTAG) metrics were calculated for two cities using these land cover/use maps. Analyzes of urban areas with landscape metrics allowed objective evaluations to define the structure of urban areas and representation of differences or similarities in the spatial structure of different urban regions.
