Description

This dataset contains national-scale forest attribute maps over France (2018-2024): 

  • FORMS-T Height: Canopy height map at 10 m resolution. Units are in centimeters (10⁻² m).

  • FORMS-T Above-Ground Biomass: Biomass map at 30 m resolution. Units are in megagrams per hectare (Mg ha⁻¹).

  • FORMS-T Growing Stock Volume: Wood volume map at 30 m resolution (WVD files). Units are in cubic meters per hectare (m³ ha⁻¹).

For detailed methodology and validation, please refer to the associated publication (https://doi.org/10.1016/j.rse.2025.114959).

Recommended usage: The products can also be visualized and accessed in Python without downloading, via the following Spatio-Temporal Asset Catalog (STAC): https://browser.stac.teledetection.fr/collections/forms-t. A Python code snippet to access and use the data via STAC is available here.

Alternatively, the products can be downloaded as .tif files directly from this Zenodo repository.

Products can also be visualized in QGIS following the instructions provided in the CDS Theia Montpellier catalog or by adding XYZ tiles directly.
