This study presents significant spatial and temporal aspects of solid waste management on a case study conducted at the Istanbul Metropolitan area, where existing models of waste management have significant limitations due to limitations of handling spatiality and temporality. Since the decision making process should be performed over time and across space, remote sensing technology provides mature solutions. In order to analyze the changes IRS 1C PAN (5×5 m spatial resolution and dated 2000) and the IKONOS MS (4×4 m spatial resolution and dated 2004) images have been used. For the landfill areas, Istanbul Metropolitan area currently involves two sites, 1/5000 scaled map and both satellite images were overlaid in order to visualize the differences between reserved area and used area of the landfill. In order to analyze the flow direction of landfill areas towards watershed areas a Digital Elevation Model (DEM) was constituted and analyses were performed. The spatial and temporal changes of the two landfill areas were detected and results were discussed. © Springer-Verlag Berlin Heidelberg 2011.
