In other words, a map highlights the relationship presents between different elements, such as objects and regions, present in the area that it represents. A map can also be defined as a representation of whole or a portion of Earth on a levelled surface to a specific scale. Maps gained their utility from the fact that they were much easier to carry, utilize as well as store then globes, and significantly eased the development of representation on different scales that were both larger and smaller than those possible on globes (Government of Minitoba, 2011). However, while maps allowed for such enhancement, they also introduced several complexities in the art of map drawing (cartography). One of the major problems that were faced by cartographers was the accurate representation of an ellipsoid object on a flat mapping surface. As a result of research on this topic, map projections were introduced. Map projections are methods which are used to represent whole or part of a sphere or a three-dimensional body on to a planar surface (Riesterer, 2008). In terms of earth mapping, map projections were initially used to transfer the features of a globe , such as coordinates and outlines of land areas on to a piece of map. ...
