Introduction The development of GIS was a result of spatial data analysis (Goodchild and Robert 2003) in the same token GIS has advanced the management of spatially referenced data. The foundation of GIS as a result is spatial analysis because it involves operations such as transformations, manipulations and other methods that are applicable to GIS to improve the data values. In turn this will encourage decisions, exposing patterns or trends not easily identifiable and anomalies. The process of spatial
“What is GIS?” Geographic information science (GIS) is a multidisciplinary field, which is flourished over past three decades [1]. As a scientific discipline, GIS helps the process of understanding spatial issues. It is used to record, manage, integrate, manipulate, analyze, and present the geographic information [1,2]. Taking advantage of these powerful functions, GIS has been widely used in various fields [3]. “System or Science?” In the early 1960s, the geographer Roger Tomlinson, the “father
