View the cadastral map of the Netherlands
Parcel boundaries, parcel numbers and building outlines per address. Below is what you can view online for free, what the Kadaster charges for, and how to work with cadastral data once one parcel is no longer enough.
What is a cadastral map?
A cadastral map shows the official division of the Netherlands into parcels: parcel boundaries, parcel numbers and the outlines of the buildings on them, based on the public register maintained by the Kadaster. The geometry is free to view through the open PDOK services. The map shows no owners: who owns a parcel is a separate, paid request per parcel at the Kadaster.
A cadastral map shows the official division of the Netherlands into parcels: the contiguous pieces of land the country is legally divided into. You see parcel boundaries, parcel numbers and the outlines of the buildings standing on them, based on the public register maintained by the Kadaster. Together those parcels form the map layer underneath almost every real estate decision in the Netherlands.
Every parcel has a unique designation built from three parts: the cadastral municipality, a section letter and a parcel number. That combination is the address of the land, and unlike a street address it does not change when a building is demolished or rebuilt. On a split or merge the old number lapses and the new parcels each get their own.
Worth knowing: the cadastral map itself does not show owners. The map shows geometry, while ownership sits in a separate register you request per parcel. The buildings on the map also come from a different source than the parcels: building outlines, construction years and floor areas come from the BAG, the cadastral boundaries from the cadastral register.
Revelop uses that cadastral structure as a foundation and layers real estate and market data on top, so you see not only where a parcel sits but what stands on it, how it is used and whether it is moving. Looking for land rather than buildings? See buying building land and the land price per municipality.
How to read a cadastral map
Four elements determine what you see on the map. Know those and you can read any parcel in the Netherlands.
Parcel boundary
The line bounding the legal piece of land. Note: this is an administrative boundary, not a surveyed property line. A fence can sit centimetres off it.
Parcel number
The unique designation of cadastral municipality, section and number. This is what you use to request any further information about the parcel.
Building outline
The footprint of the building on the parcel, sourced from the BAG. One parcel can hold several buildings, and one building can span several parcels.
Cadastral size
The registered surface of the parcel in square metres. This is the land area, not the floor area of the building on it.

Viewing cadastral data online
The cadastral map itself is public. You can view parcel boundaries, parcel numbers and cadastral size online for free, both via the Kadaster and via the public map viewers running on the same open dataset. For looking at a single parcel, that is enough.
What is not free is the substantive information behind the parcel. Ownership information, sale prices and mortgage records are paid products you request per parcel. For one address that is perfectly workable. For a street, a district or a whole municipality it adds up fast, in cost and above all in time.
Where the free route runs out
Free map viewers are built for looking, not for working. You cannot filter on parcel size, zoning is not in there at all, you cannot search on attributes instead of addresses, cannot export a selection and get no signal when something changes. The moment your question shifts from this parcel to every parcel matching my criteria, the viewer is the wrong tool. That is what Revelop is built for.

Cadastral map via PDOK
Parcel boundaries and numbers come from the cadastral register maintained by the Kadaster; that geometry is open data, free to view through the PDOK services.
BAG via PDOK
The building outlines, construction years and floor areas on the map come from the BAG, a separate source, also open via PDOK.
Ownership information (paid)
The cadastral map shows no owners. Who owns a parcel is a paid request per parcel, for example at the Kadaster.
