About sitedia
Last updated: 14 October 2026
sitedia starts from an address and draws a set of site analysis diagrams. Choose a site and a radius: you get the buildings, their use, heights, years built, zoning, parcels, green space and water, roads, stations and stops, walking distance, terrain, sun and wind, in the same round or square frame for every diagram. Files download as SVG, PNG, DXF or 3D (GLB, 3DM, SKP). Measurements are in metres. The edition comes in English and Dutch; choose at the top right of the site.
Why
Site analysis diagrams are often made by hand: capture a map, redraw buildings one by one, colour them in. In the Netherlands almost everything needed is open: buildings from the BAG, heights from 3DBAG, parcels from the cadastral map, green space and roads from the BGT, all through PDOK. sitedia puts them at the same scale, in the same frame, with one legend. The analysis stays yours.
What sitedia doesn’t do
sitedia does not check a design against rules and does not tell you what can be built. The zoning diagram shows the Wro zoning plans (now the temporary part of the omgevingsplan) and, where available, function areas from the new part of the omgevingsplan: 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. An empty area does not mean no rules apply.
Nor is sitedia a survey. Cadastral boundaries are a representation, not fixed legal boundaries. Each source has its own date and margin of error. The sun, wind and thermal comfort simulations support early design: Indicative simulation, not a regulatory assessment.
Coverage
The Netherlands edition covers the European Netherlands (not the Caribbean Netherlands). Search is by address. A site’s data is fetched from PDOK and 3DBAG on first request, so the first diagram for a place can take a little longer.
Where the data comes from
- Buildings, year built and use: BAG (Kadaster).
- Heights: © 3DBAG by tudelft3d and 3DGI.
- Parcels: cadastral map (Kadaster).
- Green space, water and roads: BGT and NWB (Rijkswaterstaat).
- Zoning: Wro zoning plans (national PDOK copy), with the current plan status per site from the Dutch environment and planning system (DSO-LV), plus function areas from the new part of the omgevingsplan where available (DSO-LV Omgevingsdocumenten); heritage: Cultural Heritage Agency of the Netherlands (RCE).
- Terrain: AHN4.
- Aerial images and base map: Beeldmateriaal.nl and BRT-Achtergrondkaart (Kadaster), via PDOK.
- Address search: PDOK Locatieserver.
- Walking network, stations and stops: © OpenStreetMap contributors (ODbL).
- Wind and climate: TMYx files from climate.onebuilding.org.
The full list with licences and credits is on the Data sources page. Every diagram carries its own credit line, which stays in exported files.
How each diagram is calculated and where its limits are is explained in the Guides.
Who makes sitedia
sitedia is designed and run by one person, an urban designer. The service started in Korea and then gained US, Japanese, Spanish, UK, French and now Netherlands editions. If a diagram looks wrong or data is missing, the “Feedback” button on the site and [email protected] reach the maker directly.
