Reading a classification report

The classification report indicates the distribution of pixel values across the number of classes set in the Unsupervised Classification window, a date stamp, and the file path for the classified imagery. The classification algorithm is also listed with the input channels and the channel in the data file where the results are stored.

The report also lists the number of clusters created by the classification with the details for each cluster.

Clusters are groups of pixels with similar spectral properties. The report tells you how many pixels make up each cluster, the mean brightness value, and the standard deviation for each of the input image channels.

Note: By default, the report is sorted according to the mean of the first band; that is, the first record in the third column of the table.
