Detection of archaeological features in an UNESCO world heritage site

Some sensible sites (classified as heritage or touristic zones) can’t be investigated with classical archaeological methods. GPR measurements are very well suited for these kind of surveys due to their lightweight and rapid operation, .

The multi-channel antennas selected for this project cover a width of 150cm with each passage of the instrument and have an investigation depth of 3 meters. A robotic total station was implemented to ensure real-time high precision positioning of the GPR measurements.

Walls and pipes in the subsurface could be located by looking at constant depth sections in a 3D data cube.
