Landcover is the natural surface of the earth undisturbed by human activities. It represents vegetation, natural or man-made features and every other visible evidence of land use. Landuse on the other hand refers to the use of land by humans. Change detection is a process of identifying differences in the state of an object or phenomenon by observing it in different times. Techniques of change detection identified in this paper are pre-classification and post-classification change detection which includes image differencing, image ratioing, change vector analysis, principal component analysis, post classification comparison, etc. Various results were achieved by different researchers based on the change detection techniques and data used; Post-classification comparison was adjudged to be the most accurate procedure and presented the advantage of indicating the nature of the changes. Most studies adopted one change detection technique and visual interpretation without comparison for errors detections or inaccuracies in the change detection processes.
