Rangeland Analysis Platform - vegetation cover v2 1986
收藏资源简介：
Rangeland Analysis Platform vegetation cover v2 1986 These data represent rangeland cover estimates determined by Allred et al. (2021)<br> and as accessible on the Rangeland Analysis Platform (https://rangelands.app).<br> Values are estimates of aerial cover for the following rangeland functional groups: Band 1 - annual forb and grass<br> Band 2 - bare ground<br> Band 3 - litter<br> Band 4 - perennial forb and grass<br> Band 5 - shrub<br> Band 6 - tree<br> No Data value = 255 Although these data were produced across a broad region, they are primarily<br> intended for rangeland ecosystems. Cover estimates may not be suitable in other<br> ecosystems, e.g., forests, agricultural lands. Uncertainty values are not included. Data are in WGS84 Geographic Coordinate System (EPSG:4326); spatial resolution<br> is approximately 30m. Please attribute these data to:<br> 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）1986年版植被覆盖v2数据集。本数据集为Allred等人（2021年）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。 数据对应以下牧场功能群的地表覆盖占比估算值： 波段1——一年生杂类草与禾草； 波段2——裸地； 波段3——枯落物； 波段4——多年生杂类草与禾草； 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，其覆盖度估算值不适用于森林、农田等其他生态系统，且未包含不确定性数值。 数据集采用WGS84地理坐标系（WGS84 Geographic Coordinate System，EPSG:4326），空间分辨率约为30米。 请按以下方式引用本数据集： Allred, B.W.、B.T.
