This section covers the following topics:

• Classification Workflow: User interface (UI)-based tool for performing unsupervised and unsupervised classification
• Class Layers
• ENVI Classification Files
• Classification Toolbox Tools: Standalone tools for unsupervised and supervised classification, and post-classification cleanup

You can also use the API-based ENVI classification framework to classify data. You can iteratively train and evaluate the performance of a classifier on one dataset, then run the classification algorithm on similar datasets.
