ABSTRACT
In this paper, Non-Boolean Standardization and Weighted Linear Combination (WLC) were applied to site suitability for military barrack in Jalingo, Taraba state, using remotely sensed data and GIS techniques. In this method, factors were not reduced to simple Boolean constraints, that is, defining a location as absolutely suitable or not suitable, but were standardized to a continuous scale of suitability from “0” (least suitable) to “255” (most suitable). The WLC allows trade off of the factors, that is, a low suitability score in one factor, can be compensated for by a high suitable score in another factor. In this paper, road network, drainage and ecology conditions, distance to already developed areas, the topography as well as suitable landuse of Jalingo metropolis were considered for modelling site suitability for military barrack. The result revealed that the suitable site for military barrack in Jalingo is located in the south-eastern part of Jalingo town around Alkali Yabba settlement. This suitable site is connected by the major road from Jalingo town. The total suitable site was calculated to be “1643.54” hectares of land with a distance of 6.5kilometers from Jalingo town. The method can easily be manipulated to derive desired results because town planners may use different factors or combination of factors to model their planning.
