 # Changelog

+## Sprint 207 Governed DHMV II terrain foundation (2026-07-15)
+
+- Added a fixed official Digitaal Vlaanderen DHMV II DTM/DSM WCS registry,
+  bounded multipart GeoTIFF acquisition and exact persisted-Area clipping.
+- Validates and retains native 1 m product identity, 5 m analysis resolution,
+  EPSG:31370, Float32 nodata, TAW, acquisition period and source/output
+  checksums through ordinary Dataset, DatasetVersion and Job persistence.
+- Added exact raster-selection metrics for mean/min/max/P10/P90 height, relief
+  and slope, with explicit valid-cell coverage and computation methods.
+- Added a Mol operator and a `Hoogte & reliëf` map theme with colour-relief
+  MapLibre overlay over the existing OpenStreetMap context.
+- Explicitly keeps drainage as a future derived analysis and prohibits
+  presenting DHMV terrain/surface height as water depth or volume.
+- Added runtime/Unraid configuration and focused acquisition, GIS formula,
+  persistence, API, frontend and packaging tests without a migration.
