Webb6 apr. 2024 · The overall accuracy (OA) was 98.64% and with a Kappa coefficient of 0.98. The vegetation area had a producer accuracy (PA) of 98.24% and a user accuracy (UA) of 98.63%. The accuracy of our vegetation classification was close to previous studies [28,47], and it indicated that it is possible to estimate 3DGV with this vegetated map. WebbProducer's accuracy is also referred to as errors of omission, or type 2 error. The data to compute this error rate is read in the columns of the table. The Total column shows the number of points that were identified as a given class, according to the classified map.

WebbThe User's Accuracy is the reliability of the classes in the classified image. It is calculated as the fraction of correctly classified pixels with respect to all pixels classified as this class in the image. For instance, based on your sample data, the User Accuracy for: UA_Class1 is : 3 / 3+3 = 50 UA_Class2 is : 7 / 7 + 1 = 87.5 WebbProducer’s Accuracies: Are the sample fraction of pixels of each land cover/use class correctly assigned to their classes by the classifiers. The producer's accuracy is associated with the omission error, which occurs when we fail to map a class j pixel correctly.
