The present topographic study was elaborated within the project: ‘THE MUSEUM OF THE IRON GATES REGION and its valorization as a touristic product’. The beneficiary of this project is the COUNTY COUNCIL OF MEHEDINȚI.

The Museum of the Iron Gates Region is one of the most prestigious museum institutions in Romania, with an impressive collection of over 90,000 pieces, valuable both for its vastness and for the collections it houses. A part of this museum’s pieces come from the Roman castrum Drobeta, the bridge built by Apollodorus of Damascus at the order of Emperor Trajan, the Roman baths, the polygonal fortification from the 13th century AD, the church of the Severin Metropolis.

The Museum of the Iron Gates Region is located at 2 Independenței Street, Drobeta-Turnu Severin, Mehedinți County.

The works necessary for preparing the technical documentation, which is the subject of this study, were executed in the “Stereographic 1970” Projection System and in the “Black Sea 1975” Altimetric Reference System. For these works, the OCPI visa was obtained.

The project benefited from an integrated approach, in which both classical measurement methods, using high-precision instruments such as GNSS systems and total station, as well as advanced photogrammetric techniques, using a DJI Matrice 300 RTK drone equipped with the DJI Zenmuse P1 camera, were combined.

As a result of the photogrammetric flight, 7546 images were obtained using the “Smart Oblique” mission type. After processing in DJI Terra, which took over 50 hours, the following results were obtained: a 3D model, a very high-quality mesh, a point cloud consisting of over 320 million points, an orthophoto with a GSD (ground sample distance) of only 0.7cm/px, over a total area of 10ha.

Deliverables: site plan, topographic map with contour lines, orthophoto, digital surface model, 3D model, and point cloud.
