Precise measurements.
Meticulous documentation.
We are a land surveying practice based in Prague, working throughout the Czech Republic. We specialise in laser scanning of buildings combined with terrestrial and aerial photogrammetry. The result: accurate detailed drawings and three-dimensional models.

From consultation to precise results
Consultation and analysis
We assess what you need, propose the best survey method and prepare a schedule with a price quotation.
Fieldwork
We measure with top-end Trimble instruments and unmanned aircraft, to millimetre accuracy.
Data processing
On high-performance graphics workstations we turn point clouds into accurate drawings and 3D models.
Deliverables
We deliver in DWG, DGN, PDF and 3D formats, and arrange certification of the documentation by an authorised surveying engineer.
