Confidence levels for 2000 and 75% tree cover

Raster containing the confidence levels in defining forest and savanna distribution and boundaries for 2000 for forest defined as 75% tree cover threshold and for a probability > 0.5. The confidence levels are expressed between 0 (less confident), and 1 (more confident).本数据集为2000年的栅格（Raster）数据，用于表征森林与稀树草原的分布范围及边界的置信水平。其中森林的定义为满足75%树冠覆盖阈值且对应概率大于0.5的区域；置信水平的取值介于0（置信度较低）与1（置信度较高）之间。
