Airborn Magnetometer Survey Images

DP ME 6, Version 2, 2006. Airborne Magnetometer Survey Images, Total Field and Vertical Gradient Images Covering 11D, 11E, 11F, 11G, 11J, 11K, 11N, 20O, 20P, 21A, 21B and 21H, (200 m X 200 m Resolution).


This data set consists of 24 colour TIFF images with a resolution of 200 m X 200 m covering 12 1:250 000 NTS mapsheets, where airborne magnetometer surveys exist over Nova Scotia. Twelve of the TIFF images represent the total field aeromagnetics for the entire province, while the other twelve represent the vertical gradient aeromagnetics. Each of the 24 images also comes with an ESRI world file (.tfw) that is used by the Arc suite of products to georeference the image. The original data were collected by aeromagnetic surveys flown by the Geological Survey of Canada (GSC).
