Multispectral Feature Space Interactive
A Java interactive designed to help teach the basic concepts of what feature space is and how it is used in image classification

Interactive developed by Roberto Garcia Yunta, Peter Ersts, and Ned Horning

Landsat Feature Identification Key
The Landsat feature identification key is a guide to interpreting land cover, based on available Landsat TM and ETM+ data.
