In the urban planning it is of great importance to keep track of growth and densification of the urban sprawl, as well as the current uses and which adopted by the population. To achieve efficient planning, it is important to have a Digital Surface Model (MDS) that fits to reality in the best possible way. In Argentina, the public registry of data relating to a real estate, known as cadaster, it is the fundamental geographic reference information for a large number of geographic information management applications and systems. At present the plot is registered in plan, that is, in 2D. The different techniques that new technologies provide suggest that it is possible in the near future to have a 3D Cadastre. Therefore, this paper analyzes how to improve the accuracy in the value of vertical component of MDS generated from images taken with unmanned aerial vehicle (UAV), using ground control points (GCP) in the field and on buildings. Differences found in MDS generated with different amounts of GCP on buildings are lower both at ground level and at building level.
