Côte d'Ivoire, like many African countries, has many construction sites and we can witness the transformation of these cities. Our study is interested in Bondoukou, a city in the northeast of the Côte d'Ivoire which does not escape the major development paths. Through this study we used satellite images to have the characteristics of our study area, the map of the slopes, the digital terrain model and the land use through processing by GIS geographic information systems. We observed in the area variations in altitude between 344 and 437 meters and slopes of the order of 0, 5.57, 11.1 and 16.07 degrees. We could thus distinguish an urbanized area, an area of bare soil, an area of vegetation and an area of watercourses. Openstreetmap data was useful for us to check the consistency of our results and validate them.

Abstract: (french)
La Côte d’Ivoire comme beaucoup de pays Africains connaît de nombreux chantiers et l’on peut assister à la transformation de ces villes. Notre étude s’intéresse à Bondoukou, une ville du Nord-Est de la Côte d’Ivoire qui n’échappe pas aux grands chantiers de développement. A travers cette étude nous avons utilisé des images satellites pour avoir les caractéristiques de notre zone d’étude, la carte des pentes, le modèle numérique de terrain et l’occupation de sol à travers un traitement par les systèmes d’information géographique SIG. Nous avons observé dans la zone des variations d’altitude comprises entre 344 et 437 mètres et des pentes de l’ordre de 0, 5.57, 11.1 et 16.07 degrés. On a ainsi pu distinguer une zone urbanisée, une zone de sol nu, une zone de végétation et une zone de cours d’eau. Les données Openstreetmap nous ont été utiles pour vérifier la cohérence de nos résultats et les valider.
