SITEDIA · NETHERLANDS
Terms of use
Effective: 14 October 2026
1. Scope
These terms govern the use of sitedia (the “service”) in its Netherlands edition. By using the service you accept these terms. You can save or print this page.
2. The service
From open geographic data, the service produces site analysis diagrams, 3D models, sections and sun, wind and thermal comfort simulations.
Basic features work without an account. Pro features need a paid pass; the Pricing page lists them.
The Netherlands edition covers the European Netherlands. How complete buildings, heights, years built, parcels, zoning and green space are depends on the date, accuracy and availability of the source data. Not all data exists everywhere: for example, recently completed buildings may have no height yet. The Data sources page gives the full list.
3. Account
You can create an account with Google or with an email address. You are responsible for your account and sign-in details. An account may not be transferred or shared. The service is not intended for people under 16, who cannot create an account.
4. Paid pass
Pro features are used with a paid pass. The types of pass, prices and lengths are shown on the Pricing page and at checkout. A pass only works in the edition where you buy it: a pass from the Netherlands edition covers sites in the Netherlands.
The pass starts when the payment is confirmed and ends on the same day and time 3 months or 1 year later, depending on the pass. If the last month has no such day, it ends on the last day of that month. If you buy a pass while another is running, the new one starts when the current one ends.
The pass is a one-off payment and does not renew automatically. When it ends, free features stay available. You must be at least 18 to buy a pass.
The pass is sold on behalf of sitedia by Polar Software, Inc., which acts as Merchant of Record and processes the payment. You buy the pass from Polar; your right to use the Pro features is granted by sitedia under these terms. Payment is also subject to Polar’s checkout buyer terms. None of this limits the rights the law gives you as a consumer that cannot be excluded.
Withdrawal (14 days) and refunds are described on the Withdrawal and refunds page.
5. Results
You may use the results in student work, reports and commercial projects, respecting the licences of the source data and the required credits.
The pass gives you no rights in third-party data and does not allow bulk extraction or resale of source data. Data from OpenStreetMap (walking network, stops and stations, transit lines) is available under the ODbL 1.0, and these terms do not limit your rights under that licence. Open government data is reused under CC0 or CC BY 4.0; that reuse does not mean the Kadaster, TU Delft or any other data holder endorses sitedia or your results.
Diagrams based on the cadastral map and on legacy zoning plans are sitedia’s own processing. They are not official cadastral documents or a zoning plan in force, and must not be presented as such.
The service does not keep results in your account. Download the files you need to your device.
When you show or share a result, keep the credit line shown under the diagrams.
6. Prohibited use
The following is not allowed. If it happens, we may restrict the account after telling you the reason and how to object.
- Bypassing authentication or usage limits
- Using another person’s account without permission
- Large-scale automated requests that disrupt the service
- Infringing the rights of others
7. Liability
The results support early design. They are not a land survey, legal boundaries, or a structural or environmental assessment. They do not replace checking the rules in force or professional advice.
Sun, shadow, wind and thermal comfort: Indicative simulation, not a regulatory assessment.
Zoning: 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. Since the Environment and Planning Act (1 January 2024), the rules in force are in the municipality’s omgevingsplan. An empty area does not mean no rules apply. Check with the municipality before relying on it.
Design and safety decisions must rely on official documents and professional advice.
Nothing in these terms excludes or limits our liability for intent or deliberate recklessness, or any other liability that the law does not allow to be excluded, and nothing affects your legal rights as a consumer.
8. Changes
If we change these terms, we will announce it in the service at least 7 days before the change takes effect (30 days if the change is to your disadvantage).
9. Governing law and complaints
Send questions and complaints to [email protected].
These terms are governed by the law of the Republic of Korea. If you are a consumer living in the Netherlands, you also keep the protection of the mandatory provisions of Dutch consumer law and you can go to the courts where you live.
Effective date
These terms apply from 14 October 2026.
