Cultural and historical monument
Project:
- Topographical mapping of the status quo of the buildings in the Petrovany Castle area for the refurbishment project and preservation of the Baroque-Classicistic architectural elements, coordinated by the Regional Monuments Board
- Complete scanning of the exterior and interior of the building, black-and-white scanning
Technology:
- Terrain reconnaissance
- Building a point field (GNSS Topcon Hiper II)
- Location of ground control points, (black-and-white paper targets, reference spheres, reflective labels, and natural ground control points)

- Photogrammetry/Setting out ground control points (UMS Topcon GPT 9001A)
- Data processing
- Data development
- Registration based on ground control points/auto registration (indoors)
- Georeferencing a point cloud in a binding coordinate and altitude system (S-JTSK, Bpv)
- Point cloud classification (Trimble RealWorks 11.2)
- Data block segmentation and clearance
- Sections, elevations, point/line exports
- 3D point cloud preview
- Drawings (Bentley MicroStation Connect Edition)
Outputs:
- Situational drawing based on a valid cadastral map, supplemented with an orthophotograph
