Magnetic Images for the Davis Lake - East Kemptville Area, Nova Scotia
DP ME 364, Version 2. Airborne Magnetic Total Field, Calculated First Vertical Derivative and Calculated Second Vertical Derivative Images Collectively Covering Parts of NTS Map Sheets 21A/03, 21A/04, 21A/05, 21A/06 and 20P/13, in the Davis Lake - East Kemptville Area
Abstract
This data set consists of one TIFF and JPEG image of airborne magnetic total field, calculated first vertical derivative and calculated second vertical derivative covering parts of NTS map sheets 21A/03, 21A/04, 21A/05, 21A/06 and 20P/13 in the Davis Lake - East Kemptville area of southern Nova Scotia. The data used to generate these images and maps were supplied by the Geological Survey of Canada - Geophysical Data Centre, 615 Booth St., Ottawa, Ontario, K1A 0E9, and the Radiation Geophysics Division, 601 Booth St., Ottawa, Ontario, K1A 0E8. The original magnetic data were acquired as part of the Davis Lake - East Kemptville survey in 1987. The 24-bit colour images were produced with a 10 m pixel size. Shading was from the southeast at 35° above the horizon.
