TreeTrace_spruce: Traceability and quality assessment of Norway spruce (Picea abies) logs

The TreeTrace_spruce database contains images and measurements of 100 Norway spruce logs from Northeastern France, each about 4.5 meters long. The image database includes RGB images of large and small ends of the logs, 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.
