Summary of Spectral Band Models Used in Remote Sensing Analysis
| Spectral Representation | GLS Image Year | Description |
|---|---|---|
| Pseudo-Natural Color | 1975, 1990, 2000, 2005, 2010, 2015 | Selective activation of Landsat bands 3, 2, and 1. Ground features appear in colors similar to reality. Healthy vegetation is green, cleared lands are light, and unhealthy vegetation is brown and yellow. Roads are gray. |
| Vegetation | 1975, 1990, 2000, 2005, 2010 | Selective activation of bands 4, 5, and 1. Vegetation appears in shades of red, brown, oranges, and yellow. Soil may be green or brown. Differences in vegetation types easier to discern. |
| Color Infrared | 2015 | Selective activation of bands 5, 4, and 3. A highly detailed yet simple model to analyze vegetation. Vigorous vegetation growth is intense red, light pink is dead vegetation. |
