## Surveying and Cadastal Administration

**Regional Administrative Body**

**State Survey and Geospatial Basic Information**

**Surveying and cadastral Authority**

**Licensed Surveyor**

**      ****local   responsibility**

***real estate cadastre***
***property surveys***
***valuation of property***
***land organisation***

**Responsibility   for state territory**

***Fundamental survey ***
***Topography***
***cartography***
***(topographical map series)***
***IT- Development***

***Involved in tasks of real estate cadastre***

- European CGSIC Meeting - December 5 and 6, 2002

- SAPOS, Germany

## The real estate cadastre has the task to describe the facts of the individual parcels of land (real estate),

while the land register (Grundbuch: register of title) provides information on the legal aspects (status of ownership etc.)

- while the land **register **(Grundbuch: register of title) provides information on the legal aspects (status of ownership etc.)

**Registration of land parcels / real estate**

- real estate cadastre

- land register

- Land
- is recorded in a
- two tiered system

- Land registration

- SAPOS, Germany

**Notes:**
After the history I will tell you now something about the situation of the land registration today.
In Lower Saxony is land recorded in a two tiered system. On one side we have the real estate cadastre and on the other side the land register.
The real estate cadastre has the task to describe the facts of the individual parcels of land, here real estate, 
while the land register (in german called “Grundbuch” or register of title) gives information as to the legal aspects, status of ownership and so on.

## The real estate map

- 	contains primarily the graphic representation of
- individual parcels of land and their boundaries
- buildings
- topographic features
- results of land valuation
- nature of land use and boundaries

- European CGSIC Meeting - December 5 and 6, 2002

- SAPOS, Germany

**Notes:**
The automated real estate map has the task to automate the surveying and mapping data of the real estate cadastre and of the fundamental surveys.
