Contribution of GIS and remote sensing in the study of urban spread in Fez
Rachid Ahmed Barry, Abdelkader El Garouani & Abderrahim Lahrach
Along with the population growth, changes occur in the physical aspects of cities. Indeed, this population increase is characterized by various consequences; one of the most important is the urban spread: this is a phenomenon of development of urban areas at the periphery of cities, which generates mobility issues, finance and planning issues and so on. In environmental terms, there is an impact on the natural landscape and ecosystems. The purpose of this work was to use the possibilities offered by new technologies, including Geographic Information Systems (GIS) and remote sensing to analyze the evolution of urban sprawl of Fez (Morocco) over the last fifteen years. On a temporal dimension, we based on multi-sources documents set at different times and sufficiently spaced in time, so we could clearly highlight the changes that occurred. This included satellite imagery, digital maps, files restitution, etc. Spatially, we studied the variations in the extent of urbanized areas, and precisely we tried to find out how changed the various influences on the ground depending on their nature and use: vegetation, water bodies, urban networks, commercial and industrial areas etc.
