Module 4: Identifying Features in ERDAS

The map layout provides a visualization of three features identified with three different kinds of band combinations to highlight the targeted feature. In feature 1, (blue border), using the true color band to best highlight the water in that area. In feature2, (red border), using the false color infrared to identify snow and vegetation in that area. Finally, in feature 3, (orange border), using a custom band of red; layer 4, green: layer 3, and blue: layer 2 to provide the best visualization of the color variations in water.
