UXO-Magnetics

In order to evaluate the UXO contamination of an abandoned military site, many small areas were magnetically surveyed.

After geodetic surveying of the fields with DGPS and tachymeter at each square a magnetic survey was paced in lines using a 4-sensors-gradiometer-array. Hence measuring points had been recorded every 0.25 m. The attained magnetic data were saved digitally and instantly put for a first quality check in field. Further calculation and modelling took place afterwards in office. The adjacent image shows results of one test field, with indicated suspicious UXO anomalies.
