Gross annual increment (of AGB) (GAI) map for 2020

This dataset provides a high-resolution (10 m) pan-European map of forest Gross annual increment (of AGB) (GAI) for the year 2020, along with an accompanying standard deviation layer. It is part of the PathFinder collection of forest structure maps, which integrates Sentinel-2 satellite imagery, auxiliary geospatial layers, and National Forest Inventory (NFI) data to deliver detailed forest attribute predictions across Europe. The map supports applications in forest management, biomass estimation, carbon accounting, and ecological modeling. For methodology and data integration details, see the documentation dataset of the PathFinder collection (<a href="https://doi.org/10.18710/OEYKEG" title="Documentation" target="_blank">https://doi.org/10.18710/OEYKEG</a>) and the following publication: Miettinen, J., Breidenbach, J. et al.

本数据集提供了2020年泛欧洲森林地上生物量（Aboveground Biomass, AGB）年总增长量（Gross Annual Increment, GAI）的高分辨率（10米）地图，并附带配套的标准差图层。本数据集隶属于PathFinder森林结构地图集系列，该系列整合了哨兵-2（Sentinel-2）卫星影像、辅助地理空间图层与国家森林清查（National Forest Inventory, NFI）数据，可生成欧洲全域的精细化森林属性预测结果。该地图可应用于森林经营管理、生物量估算、碳核算以及生态建模等领域。有关方法学与数据集成的详细信息，请参阅PathFinder系列的文档数据集（<a href="https://doi.org/10.18710/OEYKEG" title="Documentation" target="_blank">https://doi.org/10.18710/OEYKEG</a>）以及下述文献：Miettinen J、Breidenbach J 等人（2025）。《PathFinder高分辨率泛欧洲森林结构地图：地球观测与国家森林清查数据的融合》。Zenodo。<a href="https://doi.org/10.5281/zenodo.17107267" title="Documentation" target="_blank">https://doi.org/10.5281/zenodo.17107267</a>。
