ABSTRACT
Urban evolution is a situation that concerns a very significant problem in today’s world. There is a rapid growth in urban areas especially in coastal regions due to many factors depending on the specificity of each country. Such situation often times have both socio-economic and environmental implications. Therefore, studies in the field of urbanization which incorporates socio-economic and environmental factors for good town planning using space technology, geographical information system (GIS) and cartography in cities are of utmost importance. Studies of this nature are lacking in most African countries and are necessary for the improvement of the quality of life. Dakar the capital of Senegal and a major city in the West-African coastal region was used as a case study. It has a population of 2,275,351 inhabitants representing 51 % of the national population. Studies have revealed that Dakar has the highest urban change in Senegal due to better basic infrastructure compared to the hinterland. The aim of the paper is to demonstrate how GIS techniques, cartography and high resolution remote sensing data can be incorporated into a decision support tool for utilization in urban management system (UMS). The urban management issues considered in solving some of the present problems posed by rapid urbanization include proper allocation of habitation zone and well defined data infrastructure. The analysis further explains the expected results and suggests some re-orientation in the application of urban management system.
