2020年中国森林枝下高空间分布数据集
收藏资源简介:
本数据集为中国2020年森林枝下高空间分布产品,首次提供了全国范围的平均枝下高(CBHa)与最小枝下高(CBHmin)两种指标。数据基于超过1117 km²的近地面激光雷达点云,通过改进的估测方法减少系统高估,并结合多源遥感数据与机器学习算法生成。空间分辨率为 1000m×1000m,数据条目2条,包括CBH_a.tif和CBH_min.tif,数据总量为242M,压缩后22.2M。
This dataset is the 2020 spatial distribution product of forest under-branch height in China, which provides two national-scale indicators, average under-branch height (CBHa) and minimum under-branch height (CBHmin), for the first time. The data is generated based on near-surface LiDAR point clouds covering an area of over 1117 km², using improved estimation methods to reduce systematic overestimation, combined with multi-source remote sensing data and machine learning algorithms. The spatial resolution is 1000m×1000m, with 2 data entries including CBH_a.tif and CBH_min.tif. The total data volume is 242M, and 22.2M after compression.
