Canopy Height Maps across 16 site in Portugal, Spain, and California computed using Machine Learning and Sentinel-2 observations

This dataset is composed by 16 Canopy Height maps across Portugal, Spain, and California, These maps were generated resorting to a machine learning model locally calibrated with Airborne Laser Scanning data and used features derived from Sentinel-2 observations. The Canopy Height maps are delivered as raster files (GeoTIFF) where each pixel corresponds to the height estimate in meters. The product is delivered with a spatial resolution of 25m, and corresponding to the years of 2019, 2020, and 2021, depinding on te study area.本数据集包含覆盖葡萄牙、西班牙与加利福尼亚州的16张冠层高度图（Canopy Height Map）。这些冠层高度图依托经机载激光扫描（Airborne Laser Scanning）数据本地校准的机器学习模型生成，并使用了源自哨兵二号（Sentinel-2）观测数据的特征。该冠层高度图以栅格文件（GeoTIFF）格式交付，每个像素对应以米为单位的冠层高度估算值。本产品空间分辨率为25米，对应年份为2019、2020及2021年，具体年份取决于研究区域。
