Measurements of the local magnetic field can be used to detect variations of environmental,
engineering and archaeological significance.
By measuring the local magnetic field within a survey area it is possible to pinpoint areas where the magnetic field
is anomalous with respect to the regional average. By measuring the vertical gradient of the magnetic field the sensitivity of the
technique to variation in the upper few meters of the sub-surface is increased making the method applicable for detection of ordnance
and high-resolution surveys of development sites.
Anomalies are often attributable to the presence of ferrous objects and changes in
geology. Anomalies found during processing can be represented in single profiles or upon highly detailed maps superimposed upon your CAD-based
topographic survey. With our interpretation skills we can also estimate target depth and orientation.
