GIS-BASE BUILDING SITE SUITABILITY ANALYSIS OF PART OF UNDEVELOPED AREA IN GIDAN KWANO CAMPUS, FUT MINNA

Abstract

This research adopt a Geographical Information System (GIS) sieve mapping approach to select suitable sites for siting buildings in part of undeveloped area of Federal University of Technology, GidanKwano campus, Minna, Niger State. This is to minimize cost of construction usually associated with some environmental factors using spatial analyst tool of ArcGis 10.1.to overlay map layers of constraint to produce a visual representation of the suitable areas for siting buildings. The constraints considered include slope of the surface area, areas not inside or close to stream and swamp. The criterial are slope not above 25% and sites area above 2000Sqm. XYZ data was obtained from ground survey using the Hi-Target V30 GNSS receiver to produce the topographic map of the area. The final result showed that only four (4) site are suitable for siting building covering an area of 20.54Ha (37.14% of the total area) out of the total size of 55.30Ha. The final map showed that the northern part of the study area is most suitable for siting building
