In this episode, we hear how Landsat helps monitor vulnerable rangelands in the Western U.S. Interstates and other major roads. Component cover were harmonized so that the sum of bare ground, shrub, herbaceous, and litter cover adds to ~100% and secondary components sagebrush and annual herbaceous cover were harmonized to their respective primary components of shrub and herbaceous cover, (so their cover could not be greater than their primary component).
