+## Landgebruik Vlaanderen 2025: forest and agricultural use
+
+- Catalog:
+  `https://www.vlaanderen.be/datavindplaats/catalogus/landgebruik-vlaanderen-toestand-2025`
+- WCS coverage: `lu:lu_landgebruik_vlaa_2025_v3`
+- Source CRS: EPSG:31370
+- Native grid: 10 metres
+- Forest class: 12
+- Agricultural-use classes: 13 (arable) and 14 (grassland in agricultural use)
+
+GeoIntel validates the categorical source grid and persists a binary analysis
+mask for the requested product. Forest hectares are grid-derived land-use
+hectares, not legal forest boundaries, canopy cover, tree counts or wood
+volume. Agricultural-use hectares describe land use and are not ALZ parcel
+declarations, crop registrations, ownership boundaries or legal zoning.
+Definitive ALZ yearly snapshots remain a separate historical series.

+Bounded map acquisition retains official biological evaluation and habitat
+attributes. Exact intersection hectares are used for BWK value classes.
+Natura 2000 and regionally important biotope hectares derived from `PHAB*`
+shares are marked as estimates because shares belong to the complete source
+polygon and are proportionally scaled after clipping.

+## DOV digital soil map in the map flow
+
+The `dov_soil_types` product uses
+`https://www.dov.vlaanderen.be/geoserver/wfs`, collection
+`bodemkaart:bodemtypes`, stable WFS 2.0 paging ordered by `gid` and a
+consistent `numberMatched`. Geometry is clipped in EPSG:31370 and persisted in
+EPSG:4326. It remains an authoritative historical 1:20,000 baseline based on
+field work from 1949-1971, not a current drainage statement or site
+investigation.
