14-15 March 2013
Joint NSI NMA GISCO 2013 Workshop

3. Background
The interest in accessing and contributing to the GEOSTAT 1B population grid based on data from the Census 2011
GEOSTAT 1B was asked to prioritize the efforts on the “bottom-up” methodology in the GISCO workshop 2012
A GEOSTAT 1B websurvey showed that most members of EFGS will publish their Population and Housing censuses before mid 2013.

4. The GEOSTAT 1B response
Statistics Finland in flagship position prepared an initial design
First round of contributions by the project partners presented at a workshop in Oslo, June 2012
Second round of contributions until September
First draft version in September
GEOSTAT 1B meeting in front og the EFGS Conference 2012 in Prague
Finalisation of training material and guidelines until the end of 2012.
Amendments and modifications of the material until February 2013
Invitation letter sent out on the 7th of March

5. Invitation asking for contributions
The invitation letter assembles the various products from the first year of GEOSTAT 1B:
Quality Assessment of empty LAEA (ETRS89 / LAEA Europe) grid
Training material on how to produce population grids based on georeferenced register or census data
How to standardise the resulting data and make it Eurostat compliant
How to carry out a Quality Assessment of the resulting population grid data
What variables to contribute with
How to clarify the license conditions related to the produced population grids

6. What to contribute with
EFGS Standard for official statistics
Population variables
Complete list of variables including population, households, dwellings, buildings, agriculture variables
In Geostat 1B; primary focus on following population variables:

7. How to contribute, 1 How to go from point to ETRS89 / LAEA Europe grid

8. How to contribute, 2
How to go from national grid to ETRS89 / LAEA Europe grid

9. How to contribute, 3
Quality Assessment of empty LAEA (ETRS89 / LAEA Europe) grid
Comparing the spatial extent of the grid net with national reference data as borders, micro data
Making the population grid data Eurostat compliant
Data structure of each grid cell, stored as semicolon delimited csv file

10. Geostat quality assessment parameters
Combination of parameters for Geography and Statistics = Parameters for Geospatial data / Geostatistics
Proposal by benchmarking INSPIRE and Census:
INSPIRE scope of view mainly on Geography
Census scope of view mainly on concepts, definition, representativeness
Grid data quality mainly dependent on source data/primary data and production methods
Critical measures:
Accuracy and coverage of georeferences
Data protection – if any

11. Open data licence template
This template origins from the Finnish Land Survey and is recommended to be used for all variables under the EFGS Standard for official statistics
The intention is to make datasets across Europe more accessible = reduce the number of different licences
Still, it is up to each National Statistical Institute to consider whether this licence is in line with national laws or other restrictions.
GEOSTAT 1B has chosen the Finnish Land Survey open data licence due to it's good structure and coverage of different legal aspects.
The template might be seen as a first step towards a new Creative Commons licence that covers both geographical and statistical information.
