The use of remote sensing and geographic information system (GIS) in executing terrain analysis for siting global system for mobile communication (GSM) transmitting masts

Abstract

This paper used the GIS to create a virtual reality of what exists on the ground at present, with the hope that it will aid in explaining why GSM reception is poor at the Federal University of Technology, Yola (FUTY). Secondly, ‘what-if’ scenarios were created in order to locate transmitting sites that will ensure maximum coverage at the FUTY. A descending arm of the Bagale hills was identified as the obstruction causing partial blockage, hence partial reception at the University. Viewshed analysis revealed that moving one of the transmitting masts westwards, would eliminate the poor reception at FUTY. The paper revealed the necessity for proper GIS terrain analysis prior to siting GSM masts.
