Project: Geostat IA
• Geostat I A (2010-2011): Focus on Visions, Precisions
– WP1:Vision
 Vision for User needs from a data users and a data producers
perspective.
– WP2: Data
 Establish foundation for Iterative evolution of the Essnet dataset
– WP3: Infrastructure
 Visions for infrastructures
– WP4: Distribution, dissemination exploitation
 Establish channels for direct communication between users and
producers
– WP5: Examples
 None proposed for this stage of the project

Aim
• Plot the results of the EU 2010-11 population census to km
grids.
• EFGS
shall, as a formal association of NSI’s, in close
cooperation with EUROSTAT (as a compliment to
aggregations to administrative areas) in a form and
structure that responds to real user needs; over the internet,
through publications and direct communication, present an
overview of the EU 2010-11 census on km grids along with
maps, diagrams, tables, narratives and practical illustrations
of its benefits and practical use.

An Iterative Method
• Preparation phase: Geostat initiatives
– Base all work on the results from the Geostat initiative concluded by
(Feb. 2010)
• Iteration 1: Geostat Essnet I A&B
– Most if not all components in a tentative embryonic form in place by
the end of Year 2 (Feb. 2012).
• Iteration 2: Geostat Essnet II A&B
– Mature the infrastructure, improve the datasets, illustrations,
dissemination technology by the end of Year 4(Feb. 2014)

Obstacles
1.
A new disaggregation strategy
–
2.
A distributed webb portal for WSS
–
3.
That we need a dedicated portal for geostatistics for dissemination
and experiments towards a true WSS (Webb Statistical Services).
A set of good illustrations
–
4.
That the potential use of the corine landcover combined with
NUTS statistics for disaggregation is exhausted.
For the efficient DDE of Geostatistics, good examples (best
practices) to illustrate the power of the grids for spatial analysis are
needed.
A formal organisation of NSI’s
–
We need a formal organisation for the EFGS

1. New Disaggregation strategy
• Concerns WP2 and WP4 Tasks:
• A dedicated task to support a post- Corine pan European
initiative
– Efforts to substitute crude Corine data with a better dataset (GMES,
Harmonised European map dataset (ca. 1:25000 ?)
• A dedicated Task to support National Grid initiatives.
– Projects to support the development of km grid datasets based on
the each countrys special conditions
• A methodological Project to handle ”mixed mode”
harmonisation challenges
6
2. A Distributed webb Portal
• Concerns WP3 and WP4:
• We are producing visions for Portal, Metadata, WSS and
and a business model.
• We need to establish the embryo for an Portal with ESS om
the EFGS website (www.efgs.org).
– Use of Open source solutions for:
 WMS to show large grid datasets (difficult)
– Maps, diagrams, tables as well as narratives with references
 Meatadata for statistics in general and spacifically for geostatistics
– Dedicate schema for statistics, INSPIRE schema for maps (?)
 Illustrations , Case studies(demonstrations)
7
3. A Set of good Illustrations
• Concerns WP4 (DDE)
• A set of good illustrations
– Presented as a set of unified Posters, a set of slides and a webb
presentation
• Examples
– Manmade: Urban studies (Inner differentiations, outer delineations)
 Day vs. Nighttime populations, travel to work patterns, commuter
regions etc.
– Natural: Coastal areas (Interaction between Sea and land)
 Access to waterfronts, Pollution of rivers, lakes and waterfronts,
eutrophication etc.
– Sociocultural: Quality of life studies
– Economic: Business and industrial clusters.

4. A formal organisation for EFGS
• Concerns the whole project
• Formalized link between NSI’s and Eurostat
– To serve as a professional reference group in all issues related to
geo.statistics
• Contents.
– Mandate from NSI’s
 Statistical offices and public institutions as primary fee paying members
 Individuals and businesses secondary members
– An EFGS office and a dedicated Webbsite
 Portal for access to datasets, Project reporting, Discussion goups, Links
etc.
– Organised Expert groups
 Channel to publish articles, reports and presentation of Geostatistics

Conclusions
Priorities:
–
1.
To have the essential components for a whole solution in place for
the first iteration by February 2011
The new approach to disaggregation

2.
Concrete solutions for WSS on the EFGS portal

3.
Tasks and deliverables for WP3 and WP4
A set of good examples for DDE

4.
Tasks and deliverables for WP2 and WP4
A new WP5
Formalisation of the EFGS

The whole project
