+# Datavindplaats Source Roadmap
+
+This roadmap lists public Vlaamse Datavindplaats sources that are strong
+additions for GeoIntel after the current Mol/Kempen foundation. Every source
+must still receive a governed operator contract, source evidence retention,
+CRS/unit validation and selection metrics before being shown as loaded data.
+
+## P1 - Hydrology And Water Risk
+
+### Vlaamse Hydrografische Atlas - Waterlopen
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/vlaamse-hydrografische-atlas-waterlopen-toestand-03-02-2026
+- Service: https://www.vlaanderen.be/datavindplaats/catalogus/ogc-api-features-vlaamse-hydrografische-atlas-waterlopen
+- Type: vector watercourse axes.
+- Value: replace mixed GRB water context with authoritative watercourse
+  network metrics: length by category, navigable/non-navigable classes,
+  manager, basin/zone context and proximity to selected area.
+- Caveat: line network is not water surface, discharge, depth or volume.
+
+### Afstromingskaart - meervoudige stroomlijnen
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/afstromingskaart-meervoudige-stroomlijnen
+- Type: 5 m GeoTIFF, EPSG:31370.
+- Value: runoff-risk and drainage-context layer for drawn rectangles and
+  parcels; useful beside DHMV and VMM flood scenarios.
+- Caveat: modelled potential flow pattern, not observed water movement.
+
+### Overstromingsgevoelige gebieden pluviaal/fluviaal
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/overstromingsgevoelige-gebieden-pluviaal
+- Type: watertoets/informatieplicht map layer.
+- Value: policy/legal flood-sensitivity overlay complementary to the current
+  VMM modelled water-depth scenario rasters.
+- Caveat: do not merge with VMM depth rasters into one metric; it answers a
+  different policy question.
+
+## P2 - Soil, Infiltration And Erosion
+
+### Digitale bodemkaart van het Vlaams Gewest: bodemtypes
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/digitale-bodemkaart-van-het-vlaams-gewest-bodemtypes
+- Type: vector polygons, EPSG:31370.
+- Value: soil texture/drainage/profile metrics by selected rectangle, strong
+  context for forest, agriculture, runoff and suitability analysis.
+- Caveat: based on historical field data from 1949-1971; current drainage can
+  differ.
+
+### Potentiele bodemerosiekaart per perceel
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/potentiele-bodemerosiekaart-per-perceel-2023
+- Type: parcel-level erosion sensitivity.
+- Value: erosion risk by selected area, especially useful with agricultural
+  parcels, slope/DHMV and runoff.
+- Caveat: potential erosion modelling; not observed erosion damage.
+
+### Fysische systeemkaart
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/fysische-systeemkaart
+- Type: generalized physical-system zones.
+- Value: quick landscape-system interpretation: soil, relief, hydrological
+  setting, infiltration/kwel sensitivity.
+- Caveat: coarser interpretive layer, not parcel-scale evidence.
+
+## P3 - Spatial Planning And Built Environment
+
+### Ruimtebeslag - Vlaanderen - toestand 2025
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/ruimtebeslag-vlaanderen-toestand-2025
+- Type: 10 m GeoTIFF, EPSG:31370.
+- Value: built-up/settlement pressure metrics and evolution, complementary to
+  land-use and GRB building footprints.
+- Caveat: settlement-area concept, not individual building footprint.
+
+### Open ruimte - Vlaanderen - toestand 2022
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/open-ruimte-vlaanderen-toestand-2022
+- Type: 10 m GeoTIFF, EPSG:31370.
+- Value: open-space share per selection and regional fragmentation analysis.
+- Caveat: derived from land-use/space-occupation/core logic; keep method
+  separate from raw land-use classes.
+
+### Kernen, linten, verspreide bebouwing - toestand 2022
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/kernen-linten-verspreide-bebouwing-in-vlaanderen-kernen-toestand-2022
+- Type: vector typology.
+- Value: readable urban morphology: core/lint/dispersed-building context for
+  Mol and Kempen.
+- Caveat: algorithmic morphology; not a legal planning boundary.
+
+### Verstedelijkt, randstedelijk en landelijk Vlaanderen - toestand 2022
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/verstedelijkt-randstedelijk-en-landelijk-vlaanderen-indeling-op-basis-van-statistische-sectoren-toestand-2022
+- Type: statistical-sector typology.
+- Value: high-level area profile and comparison between municipalities.
+- Caveat: analysis framework, not direct zoning policy.
+
+## P4 - Accessibility And Services
+
+### Knooppuntwaarde per ha - toestand 2022
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/knooppuntwaarde-per-ha-toestand-2022
+- Type: 1 ha raster/grid score.
+- Value: public-transport accessibility score for selected areas.
+- Caveat: modelled accessibility score, not live timetable reliability.
+
+### Totaal voorzieningenniveau - toestand 2022
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/totaal-voorzieningenniveau-toestand-2022
+- Type: 1 ha raster/grid score.
+- Value: services proximity score for living-quality and spatial-development
+  analysis.
+- Caveat: score is method-dependent and should be shown with source method.
+
+### Synthese knooppuntwaarde en voorzieningenniveau - toestand 2022
+
+- Catalogus: https://www.vlaanderen.be/datavindplaats/catalogus/synthese-knooppuntwaarde-en-voorzieningenniveau-toestand-2022
+- Type: synthesized spatial-opportunity classification.
+- Value: simple end-user layer for "where is development/accessibility strong?"
+- Caveat: derived classification; keep underlying component scores available.
+
+## Recommended Implementation Order
+
+1. VHA waterlopen plus afstromingskaart: highest immediate GIS value and
+   directly improves water/runoff analysis without pretending to know volume.
+2. Bodemkaart plus potential erosion: unlocks soil, drainage, infiltration and
+   agriculture/nature interpretation.
+3. Ruimtebeslag/open ruimte/kernen-linten: makes map selection much more
+   understandable for end users and supports evolution narratives.
+4. Knooppuntwaarde/voorzieningenniveau/synthese: adds planning-quality context
+   after the physical/environmental layers are stable.
