1. DMRG - DMCSI 05/10/2014 Collaboration between NMA and NSI, the French example

2. Background Insee = French NSI IGN = French NMA At the beginning of the 2000s –Free dessimination of the bulk of the statistical production on Insee’s website. At the beginning of the 2010s (1st January 2011) –Dessimination by IGN of high scale geographical information at marginal costs for official bodies.

3. Before 2011 The management of geographical information in the statistical process relied only on the following information coming from IGN –Paper maps –small scale basemaps –aerial photographs It was not enough for managing –the census –the labour force survey (LFS) –the delineation of urban areas –the geocoding of adminstrative sources

4. Insee had to manage its own geographical information system, that was, and still is, very expensive : –150 permanent full-time jobs for managing geographical issues for the census –10 permanent full-time jobs for geocoding the administrative sources. –100 full-time jobs, on an annual basis, every 10 years for managing the geographical issues for the LFS or urban areas Before 2011

5. Since 2011 Insee and IGN have been collaborating –2011 : experimenting, for the first time, the automatic delineation of urban areas –2016 : partially outsourcing the management of the geographical issues for the census to IGN –After 2016 : a broader and a more systematic collaboration

6. Delineation of urban areas Since 1962, after each census, Insee has delineated the French urban areas according to the following definition: –More than 2000 inhabitants –Less than 200 meters between two buildings From 1962 to 1999 the distance between buildings was estimated with paper maps, aerial photographs and over 150 000 hours of office work In 2011, the distance was given by an automatic computation of the high scale topographic layers provided by IGN. The job was done within a few months by a small team.

7. 2016 - partially outsourcing the management of the geographical issues for the census to IGN IGN will manage the bulk of the area boundaries needed to organize the field work or dessiminate the statisticals results All the new roads detected by Insee will be mapped in IGN’s GIS For the remaining geographical issues managed within Insee, IGN will provide –Application Programming Interface (API) –Various data : cadastral maps, Road network, topographics maps.

8. After 2016 a broader and a more systematic collaboration Contributing to an authorivative address register Outsourcing the remaining part of the geographical issues for the census Collaborating on the geocoding of administrative sources.

9. The collaboration process A gentleman agreement signed in july 2015 Various conventions on the management of the census will be signed shortly The organization of the next step is ongoing

10. Conclusion The collaboration between Insee and IGN For Insee –A way to focus on its core business –A way to have a more efficient statistical process –A way to feed the demand for statistics on small area For Ign –A way to adapt its business model
