Data sources
Last updated: 14 October 2026
The Netherlands edition of sitedia is built on open data. This page lists, for each dataset, the data holder, the licence and the credit we show. The credit line under each diagram names the sources that diagram uses.
Data
| Used for | Source | Licence | Credit |
|---|---|---|---|
| Buildings (outline, year built, use, status) | Basisregistratie Adressen en Gebouwen (BAG — Dutch register of addresses and buildings), Kadaster. Buildings that are only permitted, demolished or registered in error are left out | CC0 1.0 | BAG (Kadaster) |
| Building heights | 3DBAG (TU Delft 3D geoinformation and 3DGI), roof height (70th percentile) minus ground level, from AHN laser data. Buildings finished after 2022 may have no height yet | CC BY 4.0 | © 3DBAG by tudelft3d and 3DGI |
| Parcels | Cadastral map (Kadastrale kaart), Kadaster | CC BY 4.0 | Kadaster, Kadastrale Kaart |
| Green space, water and road surfaces | Basisregistratie Grootschalige Topografie (BGT — large-scale topography register); current records only | CC0 1.0 | BGT |
| Road centre lines and street names | Nationaal Wegenbestand (NWB — national road database), Rijkswaterstaat | CC0 1.0 | NWB (Rijkswaterstaat) |
| Zoning | Wro zoning plans (IMRO, now the temporary part of the omgevingsplan), national copy via PDOK, completed per site with the current plan status from the DSO-LV API «Ruimtelijke plannen opvragen» (plans adopted after the copy are added, lapsed plans removed). Reference only — Wro zoning plans (temporary part of the omgevingsplan) + new omgevingsplan functions (where available); check Regels op de kaart for the rules in force | CC0 1.0 · CC BY 4.0 | PDOK; DSO-LV — also the source of Regels op de kaart (reference only) |
| Omgevingsplan (new part) | Function areas (gebiedsaanwijzingen of type functie) from the new part of the municipal omgevingsplan (environment plan), fetched per site from the DSO-LV APIs «Omgevingsdocumenten presenteren» and «Geometrie opvragen». Where a municipality already has them, they replace the legacy zoning plan on the map at that spot; most municipalities still only have the temporary part (the legacy plans). Reference only — Wro zoning plans (temporary part of the omgevingsplan) + new omgevingsplan functions (where available); check Regels op de kaart for the rules in force | CC BY 4.0 | Omgevingsplan: DSO-LV Omgevingsdocumenten |
| Heritage (protected townscapes, national monuments) | Cultural Heritage Agency of the Netherlands (Rijksdienst voor het Cultureel Erfgoed, RCE) | CC BY 4.0 | Rijksdienst voor het Cultureel Erfgoed |
| Terrain and slope | Actueel Hoogtebestand Nederland (AHN4 — national elevation model), 0.5 m ground model | CC0 1.0 | AHN4 |
| Aerial images | Current aerial photo (8 cm), Beeldmateriaal Nederland, via PDOK | CC BY 4.0 | Beeldmateriaal.nl |
| Base map | BRT-Achtergrondkaart, Kadaster, via PDOK | CC BY 4.0 | Kadaster |
| Address search | PDOK Locatieserver (addresses from the BAG) | CC0 1.0 | PDOK |
| Coverage area (European Netherlands) | Bestuurlijke Gebieden — Landgebied (administrative boundaries), Kadaster | CC BY 4.0 | Kadaster |
| Walking network (walking distance) | OpenStreetMap, Geofabrik regional extracts | ODbL 1.0 | © OpenStreetMap contributors |
| Stations, stops and transit lines | OpenStreetMap (stations, tram, metro and bus stops, line relations) | ODbL 1.0 | © OpenStreetMap contributors |
| Wind, temperature, humidity | Typical-year weather files (TMYx, nearest station), climate.onebuilding.org | Free with credit | Climate.OneBuilding.org TMYx |
| Sun, shadow, sky view, wind, thermal comfort | Calculated by sitedia from the heights, terrain and weather data above. Indicative simulation, not a regulatory assessment | — | — |
Open government data is reused under CC0 1.0 or CC BY 4.0; for CC BY 4.0 we credit the source as above. Reuse does not mean the data holder endorses sitedia. OpenStreetMap data is available under ODbL 1.0; it is used for the diagrams and images shown, not for DXF and 3D exports.
Good to know
- Parcels are not fixed legal boundaries. The cadastral map represents the register.
- Zoning is for reference only. Since 1 January 2024 the rules in force are in the municipality’s omgevingsplan (Regels op de kaart). Legacy zoning plans can be incomplete or out of date; an empty area does not mean no rules apply.
- Heights can be missing. Recently completed buildings are not in 3DBAG yet; spires and slender towers may come out too low.
- Use is the registered use. Actual use may differ.
- Stations and stops come from OpenStreetMap and are kept up to date by volunteers; a new or moved stop may be missing.
- Simulations are indicative. Sun, shadow, wind and thermal comfort: Indicative simulation, not a regulatory assessment.
