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

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

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

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) http://www.efgs.info/geostat/1B/ GISCO - WORKING PARTY MEETING, 18th and 19th of March 2014

Production procedures for Aggregation method The aggregation method manual was produced in front of GISCO-2013 followed by guidelines and training material: http://www.efgs.info/geostat/1B/guidelines http://www.efgs.info/geostat/1B/training-material http://www.efgs.info/geostat/1B/ GISCO - WORKING PARTY MEETING, 18th and 19th of March 2014

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 http://www.efgs.info/geostat/1B/ GISCO - WORKING PARTY MEETING, 18th and 19th of March 2014

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 http://www.efgs.info/geostat/1B/ GISCO - WORKING PARTY MEETING, 18th and 19th of March 2014

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 http://www.efgs.info/geostat/1B/ GISCO - WORKING PARTY MEETING, 18th and 19th of March 2014

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 http://www.efgs.info/geostat/1B/ GISCO - WORKING PARTY MEETING, 18th and 19th of March 2014

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 http://www.efgs.info/geostat/1B/ GISCO - WORKING PARTY MEETING, 18th and 19th of March 2014
