3. Main objectives of GEOSTAT 1B
Developing guidelines for datasets and methods for linking census 2010/2011 statistics to a common harmonised grid
Building on the network, partnerships and work of the EFGS and the Geostat 1A project
Assist National Statistical Institutes (NSI) to link statistics to the geography
Provide easy and barrier-free dissemination of data and handle licensing matters

6. The importance of GISCO in GEOSTAT 1B project
Non-participating NSIs prioritised project tasks at GISCO-12 as production of guidelines and training material
Workshops focusing on delivering according to GISCO-12
Progress presentation at EFGS-12
First series of guidelines and methodology papers posted on project website (EFGS.info) early 2013
Invitation letter to NSIs presented at GISCO-13 for sharing data with the project following material posted on EFGS.info
Non-participating NSIs selected case studies at GISCO-13
Progress presentation at EFGS-13
Presenting case study and project results at GISCO-14
GISCO - WORKING PARTY MEETING,
18th and 19th of March 2014

7. Were the objectives fulfilled?
Guidelines for datasets and methods were produced for linking census 2010/2011 statistics to a common harmonised grid
The Geostat 1A project partners continued, except for the NSIs of Austria , France and Poland
The NSIs of Bulgaria and Czech Republic joined GEOSTAT 1B and started to produce grid statistics
EFGS Open License Template was developed: A standard for NSIs to be used when publishing data with no user restriction
A series of case studies was produced showing the advantages of grids
The project partners have declared their interest in producing GEOSTAT-2016 grid
The a future plan for EFGS has been drafted with possible financing mechanism for EFGS.info and EFGS Conference-2014
GISCO - WORKING PARTY MEETING,
18th and 19th of March 2014

8. GISCO - WORKING PARTY MEETING,
Deliverables
A series of deliverables have been produced in order to fulfill the objectives. This will be presented in the following slides:
The final technical report as an overview of project results for assisting NSIs to link statistics to the geography
Production procedures for the aggregation and hybrid methods including guidelines for datasets and methods for linking census 2010/2011 statistics to a common harmonised grid
A series of case studies showing the potential of geostatistics
GISCO - WORKING PARTY MEETING,
18th and 19th of March 2014

9. Final technical report
The final report presents the results of the GEOSTAT 1B project based on a selected structure as proposed by the Generic Statistical Business Process Model (GSBPM)
GISCO - WORKING PARTY MEETING,
18th and 19th of March 2014

10. Production procedures for Aggregation method
The aggregation method manual was produced in front of GISCO-2013 followed by guidelines and training material:
GISCO - WORKING PARTY MEETING,
18th and 19th of March 2014

11. Production procedures for Hybrid method
The hybrid method manual was finalised late 2013 based on the experience of Statistics Bulgaria.
Stepwise approach also including the aggregation method
This reference material will be a part in the ESTP course, 2014
GISCO - WORKING PARTY MEETING,
18th and 19th of March 2014

12. Case study: Access to Emergency Hospitals
Aim:
demonstrate the advantages of grid statistics
analyse the disadvantages of confidentiality thresholds and consequently suppression of grid cells
analyse the population’s geographical access to emergency hospitals divided by age-groups and sex
Results:
Demonstrates the advantages of grid based statistics compared to administrative boundaries for spatial analyses
This case study can potentially complement The European Core Health Indicators (ECHI) indicator 80: Equity of access to health care services
Grids give a more correct result of the population distribution, but introducing confidentiality thresholds and consequently suppression of grid cells below these thresholds may result in the loss of advantages for grid statistics
GISCO - WORKING PARTY MEETING,
18th and 19th of March 2014

13. Case study: Vegetation change detection for NSIs
New satellite data from 2015 (Sentinel-2)
will allow European NSIs to access frequent earth observations
can potentially be an important source for keeping registers updated, e.g. building register and land use data
This case study
tried to explore the possibilities for using frequent earth observations in combination with building register and land use data for detecting vegetation change in green urban areas
provides promising results: Even with low resolution it was possible to follow changes in vegetation in various land use categories
Large scale construction works were also possible to detect.
Imagery with better resolution will make this approach even more relevant
However, the stepwise methodology is applicable and promising for the years to come

18th and 19th of March 2014

14. Usefulness of the deliverables, 1
16 NSIs have so far used the guidelines for producing grids into a harmonised European grid
8 NSIs have used the guidelines for producing grids with population break-downs
10 NSIs have completed the quality assurance templates
Only 4 NSIs have filled in the Open License Template, but nearly all NSIs have declared Open license rights to their population data
GISCO - WORKING PARTY MEETING,
18th and 19th of March 2014

15. Usefulness of the deliverables, 2
Great interest in case studies voiced from GISCO workshop participants
Domino effect: Training material and regional outreach through the EFGS Conferences in Prague and Sofia resulted in greater interest in contributing to the GEOSTAT grid
Global interest: GEOSTAT 1B’s Final report recognized by the UN Statistics Division as valuable and timely for the Expert Group’s (Integration of Statistical and Geospatial Information) discussions regarding grid based vs adm. approach
