  1. 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. Before 2011 • 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

  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
