Frequently asked questions
Questions about the Netherlands edition of sitedia: coverage and search, plates and data, computation, passes, and terms.
Coverage and search
Where can I use the Netherlands edition?
In the European Netherlands (not the Caribbean Netherlands). The boundary is the Kadaster administrative land area. Sites outside it are not accepted.
What can I search for?
An address or place name; search uses the PDOK Locatieserver (addresses from the BAG). To set an exact position, search nearby and click the map.
Is the screen available in Dutch?
Yes. Choose «English | Nederlands» at the top right. The plates, legends and DXF layer names follow the chosen language.
Plates and data
Why is a building missing or without height?
Buildings come from the BAG; a building not yet registered is not on any plate, and a demolished one can remain until the register is updated. Heights come from 3DBAG; buildings finished after 2022 may have no height yet. See BAG and 3DBAG.
Can I rely on the zoning plate?
No. It is for reference only. It shows legacy zoning plans and, where available, function areas from the new omgevingsplan. The rules in force are in the municipality's omgevingsplan (Regels op de kaart). See Zoning plan and omgevingsplan.
Why is the slope plate almost one colour?
Most Dutch ground is under 0.5°. The edition uses bands at 0.5, 1, 2, 3 and 5°. See Slope.
Can I make the radius larger?
The maximum radius is 1.5 km for the plates and 1 km for the wind simulation.
Can the plate be square?
Yes. Under «Shape», choose Circle, Square or Rectangle.
Computation
How long do wind, thermal comfort and sun hours take?
About 30 s for a wind simulation at 300 m radius and about 3 min at 800 m; thermal comfort a few seconds once the wind has been computed; sun hours about 4 s at 300 m and about 28 s at 800 m. The first plates for a new place take longer, because its data are fetched from PDOK and 3DBAG.
Which time are sun and shadow shown in?
Standard time (CET, UTC+1), without summer time. In summer, add 1 hour for clock time.
Passes and payment
What is free?
Generating and viewing the set (up to 28 plates per site) and downloading PNG (after signing in). Pro features are editable SVG; colours, categories and background colour; the «Details» window; the context map; 3D massing (3D view and GLB, 3DM and SKP files); DXF; the section; and the sun, shadow, wind and thermal comfort simulations. See Pricing.
What does a pass cost?
3 months €7.99 or 1 year €15.99, incl. 21% VAT. One-off payment, no automatic renewal.
Does a Netherlands pass work in the other editions?
No. A pass is for the edition it was bought in.
How do I get a refund?
The conditions are on Withdrawal and refunds.
Terms and contact
Can I use the results in reports and competitions?
Yes, including commercial work. Keep the credit line and follow the data licences. See the Terms.
Do I have to credit the sources?
Do not remove the credit line under each plate. CC BY 4.0 data require attribution, for example «© 3DBAG by tudelft3d and 3DGI», «Kadaster» and «Beeldmateriaal.nl»; OpenStreetMap requires «© OpenStreetMap contributors». Crediting sitedia is not required.
Can I use it to show that a design meets the rules?
No. The plates are for early site studies. Zoning is for reference only and the sun, wind and thermal comfort results are indicative simulations, not a regulatory assessment.
How do I contact you?
