Abstract


The major phenomenon in our contemporary era is the high and accelerating rate of changes and extensions of urban centers. This calls for fast technique for updating the existing maps. This research demonstrated the application of Remote Sensing and Geographic Information System (GIS) in revising township map of Mubi metropolis. A conventional map of 1975 and Quick-Bird imagery of 2005 of Mubi metropolitan town were used for the map revision of the metropolis. GPS was used for picking the required coordinates; Ilwis 3.1 was used for georeferencing the satellite imagery, Arcview 3.2a was used for digitizing roads and ward boundaries. This research revealed that a lot of changes have occurred on the road network which indicated increase in the number of roads from 15.205km in 1975 to 30.023km in 2010.The built-up areas expanded from 17.3158km2 in 1975 to 23.8780km2 in 2010. It was recommended that revisions of all categories of maps should be embarked upon. The use of remotely sensed data should also be adopted for mapping purpose by the relevant government authorities for example, Federal Ministry of Survey.
