WebbUser’s accuracy ranged from 57.1% to 97.1% while producer’s accuracy ranged from 26.7% to 93.6%. The broad range of accuracy indicates a severe confusion of Barren/bare land with other land cover classes. Moreover, the measure of producer’s accuracy (Sensitivity) reflects the accuracy of prediction of the particular category. 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 chantal bachelor

The difference between the sensor spectral radiance of the red band (band4) and the near-infrared band (band5) of satellite image, gives NVDI. Generally, NVDI values are positive for soil and vegetation and theoretically the values of the NDVI vary between –1.0 and +1.0. detailed of Study Area and Data, Methodology used is given 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.

WebbThe tool calculates the user's accuracy and producer's accuracy for each class as well as an overall kappa index of agreement. These accuracy rates range from 0 to 1 in which 1 represents 100 percent accuracy. The following is an example of a confusion matrix: c_1 c_2 c_3 Total U_Accuracy Kappa; c_1. 49. 4. 4. 57. WebbA user may perform one of two roles: Producer: Someone who creates supply or responds to demand. If you think of YouTube, whenever a user adds a video, he’s acting in a Producer role, creating supply. A person answering a question on Quora is a producer, responding to demand. Consumer: Someone who creates demand or consumes supply.

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. The producer 's accuracy for class j is estimated by and the omission error by .
