Towards combating security challenges in Jimeta Metropolis using viewshed analysis

Abstract

The research was undertaken to propose strategic locations for establishing security posts in Jimeta metropolis. The issue of insecurity and increase crime rate in the study area motivated the need to study the terrain in order to effectively position security posts in the best location for efficient and maximum surveillance. Digital elevation model was analyzed and the locations of the proposed security points were determined by using the spatial analyst tool in ArcGIS software to create a viewshed. Eleven (11) proposed security posts were strategically identified based on their height and spatial locations in the study area and the height of the post was offsetted at 15m above the ground surface. The research indicated the significance of viewshed analysis in locating sites for security posts for maximum security.
