+## Landcover And Canopy
+
+Place ESA WorldCover GeoTIFF/COG files under `data/landcover` and optional canopy
+height GeoTIFF/COG files under `data/canopy`, then restart the API:
+
+```bash
+docker compose restart api worker
+```
+
+The `/api/v1/landcover/path` endpoint samples all `.tif`/`.tiff` files under
+`LANDCOVER_PATH` recursively. Canopy data is optional; when it is missing,
+`canopy_height_m` is returned as `null`.
