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 Siegen Olpe the data is maintained by TIM-online NRW. Whatever the map is called there changes nothing about its content — or about the fact that you can view it above without signing up.
