Figure-5: Classification results by data set. A) The generalized geology map used to test the accuracy of the 
classification. Blue areas represent ‘cover’ and pink areas reflect ‘basement’. B) Classification using 7 
bands TM Bands, achieving 71% total accuracy. C) Classification using magnetic susceptibility as derived 
from downward continued magnetic data. 74% accuracy achieved. D) Combined magnetic and TM data 
results in 76% overall accuracy.
