# 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:
|
|
|
|
1. select an area on the map;
|
|
2. choose a subject;
|
|
3. read source-correct measurements;
|
|
4. compare persisted observations when a valid time series exists;
|
|
5. 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](https://www.vlaanderen.be/datavindplaats/catalogus/landgebruik-vlaanderen-toestand-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](https://www.vlaanderen.be/datavindplaats/catalogus/ruimtebeslag-vlaanderen-toestand-2025)
|
|
- 10 m settlement/space-occupation raster.
|
|
- Measure occupied hectares and share beside open space and land use.
|
|
- [Open ruimte Vlaanderen 2022](https://www.vlaanderen.be/datavindplaats/catalogus/open-ruimte-vlaanderen-toestand-2022)
|
|
- 10 m derived open-space product.
|
|
- Keep its method separate from raw land-use classes.
|
|
- [Kernen, linten en verspreide bebouwing 2022](https://www.vlaanderen.be/datavindplaats/catalogus/kernen-linten-verspreide-bebouwing-in-vlaanderen-kernen-toestand-2022)
|
|
- Morphological vector typology, not a legal planning boundary.
|
|
- [WFS Bedrijventerreinen](https://www.vlaanderen.be/datavindplaats/catalogus/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](https://www.vlaanderen.be/datavindplaats/catalogus/biologische-waarderingskaart-en-natura-2000-habitatkaart-toestand-2025)
|
|
is operational regionally. It remains a current state, not an invented annual
|
|
nature series.
|
|
- [Open geodata agricultural parcels](https://www.vlaanderen.be/datavindplaats/catalogus/open-geodata-landbouwgebruikspercelen)
|
|
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](https://www.vlaanderen.be/datavindplaats/catalogus/digitale-bodemkaart-van-het-vlaams-gewest-bodemtypes)
|
|
- 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](https://www.vlaanderen.be/datavindplaats/catalogus/potentiele-bodemerosiekaart-per-perceel-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](https://www.vlaanderen.be/datavindplaats/catalogus/fysische-systeemkaart)
|
|
- 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](https://www.vlaanderen.be/datavindplaats/catalogus/knooppuntwaarde-per-ha-toestand-2022)
|
|
- 1 ha modeled public-transport accessibility score.
|
|
- [Hoppinpunten and mobility hubs](https://www.vlaanderen.be/DataCatalogRecord/c262d7d0-d90d-4695-a8c6-6427ef4abb38)
|
|
- Planned and realized multimodal points; expose status and proximity.
|
|
- [Fietssnelwegen WFS](https://www.vlaanderen.be/datavindplaats/catalogus/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](https://www.vlaanderen.be/datavindplaats/catalogus/statistische-sectoren-van-belgie-toestand-01-01-2024)
|
|
- Spatial aggregation key for population and socio-economic indicators.
|
|
- [Population density per hectare 2019](https://www.vlaanderen.be/datavindplaats/catalogus/inwonersdichtheid-per-ha-vlaanderen-toestand-2019)
|
|
- 1 ha density surface corrected against Statbel sectors.
|
|
- Report observation year and estimation method; never expose address-level
|
|
population.
|
|
- [Total service level 2022](https://www.vlaanderen.be/datavindplaats/catalogus/totaal-voorzieningenniveau-toestand-2022)
|
|
- 1 ha modeled proximity score for daily services.
|
|
- [Synthesis node value and service level 2022](https://www.vlaanderen.be/datavindplaats/catalogus/synthese-knooppuntwaarde-en-voorzieningenniveau-toestand-2022)
|
|
- End-user classification after the two component scores are available.
|
|
- [Municipality indicators](https://www.vlaanderen.be/datavindplaats/catalogus/gemeente-in-cijfers)
|
|
- 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](https://www.vlaanderen.be/datavindplaats/catalogus/hitte-eilanden-in-steden)
|
|
- Hittestress evidence with explicit year/method limitations.
|
|
- [PM2.5 concentration](https://www.vlaanderen.be/datavindplaats/catalogus/concentratie-fijn-stof-pm25-in-de-omgevingslucht)
|
|
and [GES air-quality map 2017](https://www.vlaanderen.be/datavindplaats/catalogus/ges-kaart-luchtkwaliteit-toestand-2017)
|
|
- Keep measured station trends separate from modeled area maps.
|
|
- [VHA watercourses OGC API](https://www.vlaanderen.be/datavindplaats/catalogus/ogc-api-features-vlaamse-hydrografische-atlas-waterlopen)
|
|
and [runoff map](https://www.vlaanderen.be/datavindplaats/catalogus/afstromingskaart-meervoudige-stroomlijnen)
|
|
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:
|
|
|
|
1. space occupation 2025;
|
|
2. open space 2022;
|
|
3. population density 2019;
|
|
4. node value 2022;
|
|
5. 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.
