Abstract: This report lists some of the potential benefits to Northland that airborne geophysical survey data could provide. Magnetic, radiometric, electromagnetic and gravity surveys are described, but remote sensing type surveys such as radar and lidar surveys are not included, because they are mainly topographic mapping techniques. Multispectral surveys are also not considered, because the vegetation cover of Northland would severely limit their application. (auth)
