Environmental characterization and hazard studies may recently rely upon improvements in the resolution power of aeromagnetic surveys. The increased capabilities of HRAM (High Resolution AeroMagnetic) surveys stem from lower terrain clearance, tighter line spacing, more accurate magnetic and positioning data acquisition, and enhanced data processing and display techniques. The main advantages of airborne geophysical surveys over ground based studies relate to improved access to remote, hazardous and contaminated areas coupled with extensive, yet rapid sampling. Prime current applications of HRAM include volcano and earthquake hazard assessment, ground water exploration and mitigation problems, waste site characterization and location of buried man-made ferrous objects. Development of HRAM approaches might also contribute to mitigate environmental hazards present throughout the italian territory. Hence an HRAM field test was performed in July 2000 in Friuli, north-eastern Italy to preliminary assess the capabilities and limitations of HRAM over a buried pipeline and a domestic waste site.
