1. Building and dwelling register as a base for the production of geostatistical data
The collaborative approach between the Federal Statistical Office and the Federal Office of Topography
Romain Douard | Building and dwelling register as a base for the production of geostatistical data | Workshop on Integrating Geospatial and Statistical Standards | 6-8 November

2. Mainstreet 35
Name Referent/in, Organisationseinheit / Projekt | Titel der Präsentation | Anlass | Datum

3. The challenge of addresses
For the citizen : «Home sweet home» For the postman : a place I have to go through For the administration : a place where I have to provide services For the land surveyor : a point on my map For the statistician : a location to link my data
 Needs a common understanding, common definition, common ontology
Romain Douard | Building and dwelling register as a base for the production of geostatistical data | Workshop on Integrating Geospatial and Statistical Standards | 6-8 November

4. How to work together ? Meeting of the main users at national level
Swiss Post 
Federal Directorate of Cadastral Surveying 
Representatives of the Cantons 
Swiss Federal Statistical Office  
Decisions :
A unique, harmonized address dataset is a requirement for all partners 
Addresses has to be accessible free of charge (open data) 
Romain Douard | Building and dwelling register as a base for the production of geostatistical data | Workshop on Integrating Geospatial and Statistical Standards | 6-8 November

5. What to do together
Common definition and ontology about building and address
Ordinance on building and dwelling register & ordinance on geographical names (same definition of buildings and addresses)
Instruction for the registration of the buildings by the Swiss cadastral survey and the building and housing register
Conjointly defined processes
Collaborative process for acquisition and update of the data
Unified processes for data exchange, including technical specifications

6. Cadastral surveying : organization and roles
Romain Douard | Building and dwelling register as a base for the production of geostatistical data | Workshop on Integrating Geospatial and Statistical Standards | 6-8 November

7. Building and dwelling register : organization and roles
135’000 active construction projects, identified by a federal constr. project id. number (EPROID)
2,1 millions buildings, identified by a federal building id. number EGID
2.2 millions addresses, identified by a federal address id. number (EGAID)
4,3 millions dwellings, identified by a federal dwelling id. number (EWID)
Housing
Transmission using the on-line form provided by the SFO
BDR
Transmission using a commercial software with implemented web-services
ETL
Transmission using the secured exchange platform from the SFO
Database administrated by the SFO
Building permit form
filled up by the landlord or by the achitect
Information about construction projects and buildings are transmitted by the local authorities

8. Standardization of data exchange
Promote eGovernement in Switzerland, promote innovation and sustainable solutions
Public private organisation
Objective : facilitate electronic transactions between government and business & citizens
Expert groups are working to define and develop standards

9. How buildings are registered
Semi-detached houses
Construction project
Building
Addresses
Dwelling
Stable basic data, such as age, dimension, energy supply, etc…
2 EGID , 2 EGAID
Cadastral surveying,
GIS data including parcels, buildings, addresses, etc.
Terraced Houses
BDR
EGID = Federal building identification number
EGAID = Federal address identification number
1 EGID , 6 EGAID

10. The main process (registration of a new building)
An address is assigned to new building  
Send application form for a construction project
Construction authorities of the commune
Informations about new building are transmitted
Land surveyor
Owner or architect
Register the project and building informations
EGID of new building is transmitted
Survey informations are controlled    
RBD
Federal geoportal
Geocoded addresses are published
Access the RBD to check the addresses
Check service
Building identification number (EGID) is assigned to the new building
Update the RBD with coordinates and parcel number
New building is registered with its EGID  
Cadastral DB (confederation)
FSO
Cadastral data are made accessible
Cadastral DB (canton)
Cadastral data, including EGID are transmitted  

14. Lessons learned
Standardisation between partners with different visions of the same subject needs a lot of discussions Use of identification number for conjointly defined object is a necessity Data acquisition is lot of work… but it’s nothing compared to the long-term maintenance of the database We now have a reliable information system on building and addresses, although it must still be improved !
