APPLICATION OF GIS AND AHP FOR LANDFILL SITE SELECTION

Determining the appropriate locations for landfills is one of the most critical problems. The complexity of resolving this issue comes from the large number of factors that should be taken into consideration when determining a location. Overall, the inclusion of larger number of valid factors enables selection of a more appropriate location. Geographic information systems in combination with the analytical hierarchy process representes an effective approach towards determining the suitability of locating landfills. The objective of the paper is based on the geographical information systems and ahp to determine the most appropriate location for locating a landfill. Therefore, as a case study Gevgelija-Valandovo Basin has been choose which is located in the southeastern part of the Republic of Macedonia. Based on the national and international criteria for locating landfills, 15 factors were allocated for which were determined appropriate weights. With the overlapping of GIS models we obtained the final model of suitability. The performed analysis showed that from a total of 1077 km(2), as the most suitable were selected 0.98 km(2).
