Supervised Classification in ERDAS IMAGINE: Collecting signatures/training the system

Training samples are groups of pixels that represent what is recognized as a distinct pattern, or potential class. The system uses these samples to determine the statistical criteria to be used for the classification. We demonstrate how to do this using ERDAS IMAGINE 2018.
