Editor's note
Holiday weeks tend to be quieter, but not empty. This edition focuses on infrastructure rather than applications: the data engines, basemaps, and formulas that quietly determine how far digital forestry can scale.
From Sweden’s new national timber data backbone, to analysis-ready satellite mosaics, to open libraries of forest growth formulas, the common signal is reuse. When core datasets and models become modular and accessible, innovation compounds faster than any single product launch.

WHAT GOT ME THINKING
SACCESS 2025: Ready‑to‑Use Satellite Mosaics for Sweden
Vidheim announces its part in the SACCESS 2025 project, that turns Lantmäteriet’s national satellite archive into cloud‑free, analysis‑ready mosaics of Sweden for every year since 2007. By ortho‑rectifying, harmonising and merging historic scenes with Sentinel‑2 data, they deliver plug‑and‑play basemaps that make time‑series forest analysis and change detection much faster for planners, consultants and researchers.
Axel’s notes: What stands out here is not the resolution, but the removal of friction. By turning two decades of satellite scenes into cloud-free, analysis-ready mosaics, SACCESS shifts time-series analysis from a specialist task to basic infrastructure. When historical data is already harmonised and aligned with Sentinel-2, the real work moves from preprocessing to interpretation.
If widely adopted, this kind of baseline quietly raises the floor for forest monitoring in Sweden, making long-term change detection, benchmarking and digital twins far easier to build on top of shared national data.
VIOL 3: Sweden’s New Timber Data Engine
Biometria is rolling out VIOL 3, the next‑generation national system for timber measurement, settlements and data exchange in Sweden. The new platform replaces VIOL 2 with a modern, service‑oriented architecture that can handle image‑based measurements, automate more claim handling, and plug into future digital services across mills, hauliers and forest owners
SLU’s Open Forest Formula Library Supercharges Digital Tools
SLU researcher Carl Vigren has compiled and digitised nearly 70 years of Swedish and Norwegian forestry formulas into an open GitHub library, providing a common model base for growth, yield and planning calculations. The goal is to let app builders, startups and forest companies drop proven, well‑documented models straight into their decision‑support tools—boosting transparency, reducing errors and accelerating data‑driven innovation in digital forest planning.
