Rangeland Analysis Platform - vegetation cover v2 2002
收藏资源简介：
Rangeland Analysis Platform vegetation cover v2 2002 These data represent rangeland cover estimates determined by Allred et al. (2021) and as accessible on the Rangeland Analysis Platform (https://rangelands.app). Values are estimates of aerial cover for the following rangeland functional groups: Band 1 - annual forb and grass Band 2 - bare ground Band 3 - litter Band 4 - perennial forb and grass Band 5 - shrub Band 6 - tree 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. Uncertainty values are not included. Data are in WGS84 Geographic Coordinate System (EPSG:4326); spatial resolution is approximately 30m. Please attribute these data to: Allred, B.W., B.T. Bestelmeyer, C.S. Boyd, C. Brown, K.W. Davies, M.C. Duniway, L.M. Ellsworth, T.A. Erickson, S.D. Fuhlendorf, T.V. Griffiths, V. Jansen, M.O. Jones, J. Karl, A. Knight, J.D. Maestas, J.J. Maynard, S.E. McCord, D.E. Naugle, H.D. Starns, D.

牧场分析平台（Rangeland Analysis Platform）2002年植被覆盖v2数据集。 本数据集为Allred等人（2021）生成的牧场覆盖度估算数据，可通过牧场分析平台（https://rangelands.app）获取。 数据包含以下牧场功能群的冠层覆盖度估算值： 波段1：一年生杂类草与草本植被； 波段2：裸地； 波段3：枯落物； 波段4：多年生杂类草与草本植被； 波段5：灌丛； 波段6：乔木； 无数据值为255。 尽管本数据集覆盖范围较广，但主要面向牧场生态系统，其覆盖度估算结果在森林、农田等其他生态系统中可能并不适用。 本数据集未包含不确定性估算值。 数据采用WGS84地理坐标系（EPSG:4326），空间分辨率约为30米。 使用本数据集时，请按照以下文献进行标注： Allred, B.W., B.T.
