class eoforeststac.writers.hansen_gfc.HansenGFCWriter(endpoint_url: str, bucket: str, key: str | None = None, secret: str | None = None, profile: str | None = None, region: str = 'eu-central-1', anon: bool = False)[source]#

Writer for Hansen Global Forest Change (GFC) v1.12.

Native input:

  • One VRT per variable (global mosaics)

Output:

  • Single Zarr store with harmonized Hansen variables

Notes

  • Hansen loss encoding (1–24) is converted to calendar year (2001–2024) and stored as loss_year (int16).

  • This avoids implicit conventions and aligns with TMF-style year products.
