Rangeland Analysis Platform - vegetation cover 2001

Rangeland Analysis Platform vegetation cover 2001 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. Please attribute these data to: Jones, M. O., B. W. Allred, D. E. Naugle, J. D. Maestas, P. Donnelly, L. J. Metz, J. Karl, R. Smith, B. Bestelmeyer, C. Boyd, J. D. Kerby, and J. D. McIver. 2018.
