Datavindplaats Source Roadmap
This roadmap was rebalanced on 2026-07-16 after a platform-wide review of public Vlaamse Datavindplaats sources. Water is one analysis domain, not the organizing principle of GeoIntel. The target product remains simple:
- select an area on the map;
- choose a subject;
- read source-correct measurements;
- compare persisted observations when a valid time series exists;
- inspect provenance and export evidence.
Every source below is either already operational or has an official public catalog/service record. A catalog entry is not the same as an implemented provider. GeoIntel may label a source operational only after governed import, CRS/unit validation, persisted provenance and selection-metric tests pass.
Current Operational Foundation
- Space and buildings: GRB building/road context, Buildings and Addresses Register for Mol, official land-use snapshots and orthophotos.
- Nature and agriculture: regional BWK/Natura 2000 state 2025 and definitive agricultural parcel editions.
- Soil and relief: bounded DHMV DTM/DSM acquisition with height, relief and slope metrics.
- Climate and environment: VMM flood-hazard scenarios and station-bound Waterinfo series.
- Historical context: official 1778, 1873 and 1969 mapped land-use classes and modern land-use editions where persisted.
The cross-domain Wave 1 implementation now adds population/services, modeled accessibility, space occupation, open space and the DOV soil classes to Mol. Regional completeness beyond Mol remains a controlled operator rollout rather than an automatic startup fetch.
Domain A - Space, Buildings And Economy
Highest-value additions
- Landgebruik Vlaanderen 2022
- 10 m GeoTIFF in EPSG:31370 with WMS/WCS distribution.
- Measure hectares and share by actual land-use class; do not present it as legal zoning.
- Ruimtebeslag Vlaanderen 2025
- 10 m settlement/space-occupation raster.
- Measure occupied hectares and share beside open space and land use.
- Open ruimte Vlaanderen 2022
- 10 m derived open-space product.
- Keep its method separate from raw land-use classes.
- Kernen, linten en verspreide bebouwing 2022
- Morphological vector typology, not a legal planning boundary.
- WFS Bedrijventerreinen
- Production WFS for economic areas.
- Measure total/occupied area and retain VLAIO/Digitaal Vlaanderen source status and edition.
Domain B - Nature And Agriculture
- BWK / Natura 2000 state 2025 is operational regionally. It remains a current state, not an invented annual nature series.
- Open geodata agricultural parcels is operational as annual declared-use area. Parcel identities remain intentionally unstable between editions.
- Open-space and land-use rasters complement these object layers. Metrics must not add overlapping classification surfaces as if they were disjoint.
Domain C - Soil And Relief
- Digital soil map: soil types
- Vector soil polygons in EPSG:31370.
- Measure hectares by soil type, texture and drainage class.
- Historical field mapping from 1949-1971 is baseline evidence, not a claim about current parcel drainage.
- Potential soil erosion per parcel 2023
- Modelled potential erosion, not observed damage.
- Combine with agricultural use and DHMV slope only while keeping each source and method explicit.
- Physical system map
- Coarse interpretive landscape zones for context, not parcel evidence.
Domain D - Mobility And Accessibility
- Current GRB roads provide map and length context where persisted.
- Knooppuntwaarde per hectare 2022
- 1 ha modeled public-transport accessibility score.
- Hoppinpunten and mobility hubs
- Planned and realized multimodal points; expose status and proximity.
- Fietssnelwegen WFS
- Region-wide network with realization, quality, lighting and route context.
Accessibility scores are not live timetable reliability. Network length and proximity are separate measurements from modeled accessibility.
Domain E - Population And Services
- Statistical sectors, state 2024
- Spatial aggregation key for population and socio-economic indicators.
- Population density per hectare 2019
- 1 ha density surface corrected against Statbel sectors.
- Report observation year and estimation method; never expose address-level population.
- Total service level 2022
- 1 ha modeled proximity score for daily services.
- Synthesis node value and service level 2022
- End-user classification after the two component scores are available.
- Municipality indicators
- Context for municipal comparison; not a replacement for area-level map measurements.
Domain F - Climate And Living Environment
- VMM flood-hazard rasters and Waterinfo station series are already governed.
- Urban heat islands
- Hittestress evidence with explicit year/method limitations.
- PM2.5 concentration
and GES air-quality map 2017
- Keep measured station trends separate from modeled area maps.
- VHA watercourses OGC API and runoff map remain useful, but they follow the broader cross-domain foundation. Watercourse lines are not surfaces, discharge, depth or volume.
Implementation Waves
Wave 1 - Cross-domain area profile
Implement one governed Mercator thematic-raster registry instead of separate ad-hoc provider code. Its fixed allowlist should first cover:
- space occupation 2025;
- open space 2022;
- population density 2019;
- node value 2022;
- total service level 2022.
The existing Dataset, DatasetVersion, Job and raster-selection architecture is sufficient. Each product needs a fixed coverage id, native unit/classes, observation date, resolution, legend, permitted aggregations and caveat. No arbitrary WCS URL or layer name may enter the API.
In parallel, add the digital soil map through the existing canonical vector DatasetService/VectorFeatureService path. This immediately gives every drawn rectangle a balanced profile across space, soil, people, services and accessibility.
Implementation status on 2026-07-16: complete for Mol. The five raster
products use one fixed MercatorNet registry and the soil map uses the official
bodemkaart:bodemtypes DOV WFS. All outputs are persisted through existing
Dataset services, carry source year/period and limitations, and are selectable
on the map. Regional raster provisioning is supported per persisted
municipality; regional soil partitioning remains the next scale-out step.
Wave 2 - Economic and mobility objects
Add governed vector operators for business parks, Hoppinpoints and cycle highways. Persist provider output only through DatasetService and VectorFeatureService. Selection metrics should be area for business parks, counts/proximity for Hoppinpoints and length/status for cycle highways.
Wave 3 - Living environment
Add heat and air-quality sources only after their spatial scale and temporal comparability are explicit. Then add VHA/runoff as hydrological context. Do not derive missing volume, exposure or health outcomes.
Wave 4 - Historical completeness
Search for comparable earlier editions of every accepted product. A valid series requires compatible classes and methods, explicit observation dates and persisted versions. When methods differ, show side-by-side evidence rather than a fabricated trend.
Recommended Next Sprint
Build Governed Flemish Thematic Raster Registry - Wave 1. It is the best next platform step because one bounded, allowlisted acquisition architecture unlocks spatial planning, open space, population, accessibility and services without changing the database schema or creating one-off provider paths.
Acceptance requires:
- product registry and honest capability metadata;
- bounded WCS acquisition through the existing Job/Dataset flow;
- exact Area/rectangle selection with product-specific metrics;
- MapLibre image overlay and simple legend;
- source date, unit, method and caveat in every result;
- no startup/browser fetch and no fabricated historical observations;
- focused GIS, API, persistence and frontend tests;
- one Mol live smoke before regional provisioning.
