Terminology

## Flurkarte, Liegenschaftskarte, Katasterplan — what is the difference?

None. It is the same map. Which name it carries depends on the federal state, the authority and how old the usage is. The only real distinction is between the map itself and the official document produced from it.

| Term | What it means | Where the term is official |
|---|---|---|
| Liegenschaftskarte | The official map of the German land register (Liegenschaftskataster), showing parcel boundaries, parcel numbers and buildings. | The current technical term nationwide, introduced with ALKIS. |
| Cadastral map | The same map. The older name, still in everyday use. | Still the official product name of the state survey authority in Bavaria (Digitale Flurkarte, DFK) and North Rhine-Westphalia (Amtliche Flurkarte NRW). |
| Katasterplan, Katasterkarte, Flurplan | Again, the same map. | Nowhere — colloquial, but widely used. |
| Katasterauszug, Auszug aus der Liegenschaftskarte | Not the map, but the official document derived from it — sealed, chargeable and legally binding. | Nationwide. Only the cadastral office issues it. |
| ALKIS | Not a map name but the system behind it. It merged the former cadastral map (ALK) and the cadastral register (ALB). | Nationwide, introduced in every federal state. |

For Hamburg the data is maintained by Geoportal Hamburg. Whatever the map is called there changes nothing about its content — or about the fact that you can view it above without signing up.

What it is good for

## When is the online map enough — and when do you need the official extract?

This map is enough

- Looking up a parcel number or cadastral district
- Estimating a plot's shape and its neighbouring boundaries
- Preparing for a purchase or an estate agent meeting
- A first assessment before dealing with the authorities

Official extract required

- Building applications and submission documents
- Notary appointments, purchase contracts, the land register
- Boundary disputes and surveying
- Anything requiring legally binding documentation

For Hamburg, official extracts are issued solely by Geoportal Hamburg — the responsible body is the cadastral authority of your district or independent city. Depending on the format, fees are typically in the low double digits (euros).

FAQ

## Cadastral maps, parcels & the German cadastre

### Can I view the cadastral map of Hamburg online for free?

Yes. The map above shows the cadastral parcels in the Hamburg map extent — no sign-up, no fee. 427,738 parcels are covered there. It is a non-binding orientation based on official open geodata, not an official cadastral extract.

### How do I find my parcel number in Hamburg?

Search for your address in Hamburg above and zoom into the map. Parcel numbers appear once buildings become visible. A click reveals the cadastral district (Gemarkung), sector (Flur) and number — this extent holds 256 districts and 926 sectors.

### How large is a typical plot in Hamburg?

Within the Hamburg map extent, half of all cadastral parcels are smaller than 791 m² (median); the mean is 3,743 m². The mean sits consistently above the median because a few large areas — forest, industry, transport — pull it upwards.

### Are the property boundaries on this map legally binding?

No. The boundaries come from open geodata published by the state surveying authority and serve as orientation. Only the official extract from the German cadastre (Liegenschaftskataster) is legally binding — for Hamburg it is issued by Geoportal Hamburg. You need that extract for a building application, a boundary dispute or a notary appointment.

### Is the Flurkarte in Hamburg also called Liegenschaftskarte or Katasterplan?

Yes, these all refer to the same map. Liegenschaftskarte is the current technical term from ALKIS, Flurkarte the older name, and Katasterplan, Katasterkarte or Flurplan are colloquial variants. For Hamburg the map above shows the same content in every case: parcel boundaries, parcel numbers, cadastral district and land parcel block. The one genuine difference is the Katasterauszug — the sealed document produced from it.

### Where does the cadastral data for Hamburg come from?

From the open geodata of Hamburg: © Freie und Hansestadt Hamburg, Landesbetrieb Geoinformation und Vermessung, dl-de/by-2-0. Figures as of 2026-08-14.
