A012 AIRBORNE EM – FROM ANOMALY HUNTING TO 3D MAPPING – A CASE FROM FINLAND Abstract 1 GTK (Geological Survey of Finland) started the Finnish low-altitude airborne geophysical mapping program in 1972. Nearly 90 percent of the land area has been measured so far. During the last ten years airborne EM (AEM) data have turned into a base material in many ground water land use and environmental mapping and monitoring projects. Recent improvements in measurement and interpretation techniques have been giving rise to detailed subsurface conductivity models and expanded the use of AEM data to new applications.
