A confusion or error matrix is considered to be the most widely well known and used accuracy assessment method. (Foody 2002) A simple cross-tabulation of the mapped class label against that observed in the ground or reference data, provides an obvious foundation for
accuracy assessment. (Campbell 1996) The final classification overall accuracy was achieved as 84 % and the KIA (Kappa Index of Agreement or Kappa Coefficient) as 77 %.
