TECHNOLOGY: CROSSHOLE TOMOGRAPHY
Crosshole tomographic measurements use existing drillings for the transmission and the registration of geophysical signals.
Wave methods like GPR and seismics as well as geoelectrical measurements are suitable.
   
The objective of the crosshole method is the 2D or 3D detail exploration between drillings.
A great advantage of crosshole tomography is also a higher resolution of underground structures in greater depths.
