Examination of the environmental factors in locating a landfill using Geographic Information system and remote Sensing techniques
Barlakoska, L.
In this study, Geographic Information System and Remote Sensing techniques are employed in conducting an investigation of the environmental criteria for assessing the study area suitability for hosting a landfill. The overall waste management situation at this time in the Former Yugoslav Republic of Macedonia can be freely characterized as substandard, the main constraints being from technical and financial nature. Ten environmental criteria, five factors and five constraints, were applied. 26 GIS map layers were produced using topographic, geological and CORINE land cover maps as well as Landsat ETM+ satellite images. The factors were input in the weighted overlay analysis tool in ArcMap and weights were assigned. The constraints were merged in one `0 layer`. Compiling both the factors map and the constraints map, resulted in a map of suitable areas classified in 3 classes according to the suitability - least suitable, suitable and most suitable. The suitable and most suitable areas represent 414,38 ha or 4,65 percent of the total study area of 8895,7 ha with latitude 41 degrees 19' 60 N and longitude 21 degrees 22' 0 E. This study can be further used for assessing the environmental cost for optimizing the landfill site by applying social and economic criteria.
