Glossary for Geospatial Science

tag:  A temporary number that can be assigned to a class in the Training Set Editor of the Auto-Classification process.  For example, you import a set of classes into the Training Set Editor.  Each class has a value when it is imported.  If a class does not have the value that you want to use, you can assign a tag number to the class.  You can assign different tag numbers to as many different classes as you wish.  When you assign the same tag number to more than one class, the Training Set Editor merges the classes.
