Rangeland Analysis Platform - vegetation cover 2019

Rangeland Analysis Platform vegetation cover 2019

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.

牧场分析平台2019年植被覆盖数据集
本数据集由Jones等人（2018）提出，可通过牧场分析平台（Rangeland Analysis Platform，https://rangelands.app）获取。数据包含以下牧场功能类群的百分比覆盖度值：
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

尽管该数据集覆盖范围较广，但主要面向牧场生态系统，其覆盖度估算结果不适用于森林、农田等其他生态系统。

本数据集采用WGS84地理坐标系（EPSG:4326），空间分辨率约为30米。
