Airborne Gamma Ray Spectromatric Survey Images

DP ME 5, Version 2, 2006, Airborne Gamma Ray Spectrometric Survey Images, Elemental and Elemental Ratio Images Covering 11D, 11E, 11F, 11G, 11J, 11K, 11N, 20O, 20P, 21A, 21B and 21H, (250 m x 250 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 gamma ray surveys exist over Nova Scotia. Twelve of the TIFF images represent the radioelements for the entire province, while the other twelve represent the ratios of the radioelements values. The original data were collected by aeromagnetic surveys flown by the Geological Survey of Canada (GSC). rd_250_xxx.tif Series: Band 1: %K - Potassium Band 2: eU - equivalent Uranium Band 3: eTh - equivalent Thorium rr_250_xxxx.tif Series: Band 1: eU/%K - equivalent Uranium/Potassium Band 2: eTh/%K - equivalent Thorium/Potassium Band 3: eU/eTh - equivalent Uranium/equivalent Thorium. These are the .tiff images showing ratios of radiometrics values for the entire province.
