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.
