Rangeland Analysis Platform - vegetation cover 2014

Rangeland Analysis Platform vegetation cover 2014 These data represent rangeland cover estimates determined by Jones et al. (2018) and as accessible on the Rangeland Analysis Platform (https://rangelands.app). Values are percent aerial cover of the following rangeland functional groups: Band 1 - annual forbs and grasses Band 2 - bare ground Band 3 - litter Band 4 - perennial forbs and grasses Band 5 - shrubs Band 6 - trees No Data value = 255 Although these data were produced across a broad region, they are primarily intended for rangeland ecosystems. Cover estimates may not be suitable in other ecosystems, e.g., forests, agricultural lands. Data are in WGS84 Geographic Coordinate System (EPSG:4326); spatial resolution is approximately 30m.
