Acquisition and Processing of Topographic Data in Order to Develop a Topographic Map Delimiting the University Cities (Case of the University of Lubumbashi, DRC)

This study consists of developing a topographical map delimiting the University Cits de Lubumbashi, Democratic Republic of Congo. For this, we examined the location of the extent of the land in question, we took into account the invasion of the private within the concession as well as see what type of Topographic material used, adapted to the state of this terrain, to achieve a good acquisition of Topographic data, which are the essential elements for drawing up the map. A comparison of the current area to the initial area of this land, allowed us to see the impact caused by the invasions of the private within this concession which led to a considerable loss of hectares known to the University. . To achieve our objectives, we relied on certain data (the coordinates of different points), obtained by topographic ground surveys carried out in the field, with the Total Station (TopconDs: 103 A) and DGPS (Topcon) as equipment, as well as the parametric analysis of these data and the use of Google Earth and Arc GIS 10.4 as topographic data processing software, which the rest of the work will be responsible for clarifying, revealed that following the results obtained, the University of Lubumbashi, its current area of its concession has a perimeter of 6.84 km with an area of 1.49 km2 equivalent to 149 hectares. However, it has been three decades since the Cits Universitaires concession occupied an area of 557.90 hectares. Finally, we have made some suggestions for a rational management and conservation of this concession of University Cities.
