3. Major GI Policies: "geo-referenced buildings register"
To support continuous census
As wall as many other needs:
Municipalities administration
Utilities management
Emergency services
Services for the citizens
Pinpoint every address in France

Address component
First stage, 2003:
An existing data base of georeferenced address ranges
An address information DB (to be chosen)
Second stage, 2006: georeferencing of address information DB  Address point data base
2003/10/23-24
French policies related to GI

5. Address component - issues
Choice of the first set of address points
Privacy issues: e.g., National council on information distribution (CNIL) restrictions on distributing such data sets as the INSEE RIL
Cost of creating and maintaining the data set
RIL Creation :
100 employees during 2 years for addresses
RIL Update : 30 persons each year
INSEE to bring in its expertise, and knowledge of standards

6. Major GI Policies: dematerialising the Cadastre
Partnerships with local governments and their partners
Vector cadastre
Scanning of cadastral maps
All non vector maps
=>2005 on-line sheet by sheet cadastre
2003/10/23-24
French policies related to GI

7. Major GI Policies: large scale reference data
RGE as 4 components
Orthophoto
Topography
Land parcels
Addresses
Registered to each other
=>2007 RGE as an infrastructure for GI
2003/10/23-24
French policies related to GI

8. French policies related to GI
Orthoimage component
Based on existing BD ORTHO product
Nation wide: 1 meter accuracy, 50 cm resolution colour coverage
Urban areas: Higher resolution coverages (25cm, 12.5cm)
2003 first coverage, then 5 years update cycle
2003/10/23-24
French policies related to GI

9. Topographic component
Based on existing BD TOPO product
Nation wide: 1 meter accuracy, 2.5D data from stereoplotting
Urban areas: Specific larger scale coverage
Completion expected by 2007
Continuous update process being put in place
2003/10/23-24
French policies related to GI

10. French policies related to GI
Land parcel component
MoU between Cadastre Office and IGN
Scanned sheets passed to the IGN
Georeferencing, and assembling of cadastral sheets
Consistent with orthoimagery and topographic features

Adresse Niveau 1 12
Adresse Niveau 2 6 4 2

French policies related to GI

12. Respective role of traditional players
Data providers, and interface with local governments (INSEE statistical office, DGI cadastral administration)
Producer, integrator, and distributor of data collected by third parties (IGN national mapping agency)
2003/10/23-24
French policies related to GI

13. RGE acquisition policy
Wherever data is already available, and can be integrated in RGE: Try to do a deal:
Integration of data in the RGE
IPR retained by the original producers/owners
But full distribution rights of this RGE subpart passed to IGN
Three partnership cases:
Data provider and IGN RGE distributor
Data provider and IGN co-produce, IGN distributes
Both players produce, and distribute
Else production taken care of by IGN
Either in house
Or, increasingly, by outsourcing it.
e.g., Land parcel data base production overwhelmingly outsourced
2003/10/23-24
French policies related to GI

14. Rationale for integration
Best use of public money
Faster creation of RGE
Optimised maintenance
May foster the use of reference data
Help develop consistency, and interoperability among data collections
2003/10/23-24
French policies related to GI

15. French policies related to GI
Integration
Agreements on data collection – Many signed
with the cadastre office (DGI)
Partnership on creating, and maintaining the Land Parcel Data Base
with other state agencies
IFEN (environment agency), French Railway Network agency, Électricité de France, Regional directions of Ministry, ONIC…
With local authorities
Partnership on creating, maintaining, and distributing RGE local / partial coverages (e.g., some French ‘départements’, Bordeaux city)
Outsourcing
Increasing share of topographic, and orthoimagery data production
Close to ¾ of the Land Parcel Data Base production
Issue of developing the quality control, and integration capabilities
2003/10/23-24
French policies related to GI

16. Integration: constraints
Quality:
Recognised and knowledgeable provider: Quality data
Data compatible with RGE (content and currency): Consistency of RGE data
Available coverage large enough: Efficiency
Perennial provider
Pragmatism:
Go for cost saving solutions
Comply with RGE collection timetable
Avoid too technically difficult integration
