Key message

The TreeTrace_spruce database contains images and measurements of 100 Norway spruce (Picea abies (L.) H.Karst.) logs from Northeastern France, each about 4.5 m long. The image database includes RGB images of large and small ends of the logs and hyperspectral and computed tomography (CT) images of wood discs sampled at both log ends. The 100 logs were also fully X-ray scanned with a CT device for roundwoods and their top surface was scanned with a terrestrial LiDAR device. The measurements performed on discs include wood local density, growth ring widths and pith location. This database is complementary to another one (TreeTrace_Douglas) resulting from the same ANR project TreeTrace, but if the objectives are similar, the protocols and conditions of acquisition are not the same for these two databases. TreeTrace_spruce dataset is available at https://doi.org/10.57745/WKLTJI and associated metadata are available at https://metadata-afs.nancy.inra.fr/geonetwork/srv/fre/catalog.search#/metadata/cffee2f1-18e1-4b53-9f5b-6cc4c66f1cb8.

挪威云杉 (Picea abies (L.) H.Karst.) 原木的可追溯性和质量评估：TreeTrace_spruce 数据库

关键信息

TreeTrace_spruce数据库包含 100棵挪威云杉（Picea abies(L.) H.Karst.) 来自法国东北部的原木，每根长约 4.5 m。图像数据库包括原木大端和小端的 RGB 图像以及在原木两端采样的木盘的高光谱和计算机断层扫描 (CT) 图像。这 100 根原木还使用圆木 CT 设备进行了全面 X 射线扫描，并使用地面 LiDAR 设备扫描了它们的顶面。在圆盘上进行的测量包括木材局部密度、年轮宽度和髓部位置。这个数据库是对来自同一个 ANR 项目 TreeTrace 的另一个数据库 (TreeTrace_Douglas) 的补充，但是如果目标相似，这两个数据库的协议和采集条件是不一样的。TreeTrace_spruce 数据集可在 https://doi.org/10.57745/WKLTJI 获得，相关元数据可在 https://metadata-afs.nancy 获得。
