Spectral Discrimination of Archaeological Sites Previously Occupied by Farming Communities Using In Situ Hyperspectral Data

Table 9

Error matrices showing the overall accuracy and kappa for the classification of the four soil classes, nonvitrified dung (NVD), middens (MD), nonsites (NS), and vitrified dung (VD), using optimum elements (n = 7) and the optimum bands (n = 8)

Class	NVD	MD	NS	VD	Total	UA (%)
NVD	5	1	1	0	7	71.43
MD	0	2	0	0	2	100.00
NS	0	0	2	0	2	100.00
VD	0	0	0	3	3	100.00
Total	5	3	3	3	14
PA (%)	100.00	66.67	66.67	100.00
OA	85.71%
Kappa	0.7999

PA = producer’s accuracy, UA = user’s accuracy.
