grawimetria5
Gravimetric techniques are a totally noninvasive surface geophysical method based on the theory of gravitation. The object of measurement is the vertical component of gravity. Changes in its values reflect a change in the density of the medium measured. Gravimetry can be used both in regional geology (regional and semi-detailed mapping) and local (detailed mapping) considerations, as well as in engineering geology issues (microgravity).
The territory of Poland is covered with semi-detailed gravimetric mapping with an average distance between the measurement points in the range of 550 m.

 

WE OFFER


Geophysical Methods Unit offers data processing, map visualization and gravity data interpretation:
