Google Earth Engine（GEE）——全球树木异体测量和树冠结构（Tallo）数据库

全球树木异体测量和树冠结构（Tallo）数据库 Tallo数据库（V1.0.0）收集了498,838条有地理坐标和分类学标准的单个树木记录，这些树木的干径、高度和/或树冠半径已被测量。数据来自全球61,856个地点，包括5,163个树种的测量。Tallo包括在全球6万多个地点获得的5000多个树种的近50万条地理参考和分类学标准记录，包括所有主要陆地生物群落的数据和一些世界上有记录的最大的树木。数据库中的大多数树木都被鉴定为物种（88%），Tallo总共包括5163个物种的数据，分布在1453个属和187个植物科。该数据库在CC-BY 4.0许可下公开存档。
