Abstract:

An investigation was conducted from November 2015 to May 2017 at Shahapur and Shorapur taluk, Yadgir district, to accuracy assessment of supervised and unsupervised classification for land use land cover using Landsat-8 imagery of D-7 Shahapur branch canal of UKP command area, Karnataka. Accuracy assessment of supervised land classification for post and pre-monsoon was carried out for the study period and the values are presented in Table 5 to 8. The technique used for this was called error of confusion matrix. The overall accuracy for both post and pre-monsoon ranged from 86.66 per cent to 92 per cent and Kappa co-efficient ranged from 0.81 to 0.89. The range value of classification was due to intermixing of some classes Megersa (2012), that any accuracy assessment value more than 75 per cent will be considered acceptable Giles (2008). Similarly for kappa co-efficient more than 0.80 indicate moderate and less than 0.40 indicate poor classification. Kappa co-efficient for this study were within the range expressed as good classification, hence classification yielded good results and comparable to other studies.
