Özet

Many decision tasks in disaster management are concerned with spatial patterns and spatial decision problems often require that a large number of feasible alternatives be evaluated based on multiple criteria. Although Geographical Information Systems (GIS) provide extensive spatial analysis and data visualization power to users, such systems offer a limited capacity for tackling complex spatial decision problems. Multi-criteria Decision Analysis (MCDA) methods linked with GIS can be used to make such decisions. This paper focuses on the GIS-based Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method which is one of the most popular methods in MCDA. The TOPSIS method was implemented ArcObjects/VBA in ArcGIS environment as ArcGIS-TOPSIS tool and it was tested in a real-world situation for settlement site selection in Atakum-Samsun, Turkey.
