EFGS Background
EFGS started as a voluntary cooperation between National
Statistical Institutions (NSIs) in the Nordic countries in 1998, on use of
geographic information systems (GIS) and statistics.
Today EFGS has national contact persons from 32 European states
and territories, having annual conferences and meetings.
The Steering Committee consists of the national contact persons
from the NSIs that participate in the ESSnet project GEOSTAT, mainly
funded by Eurostat.
Activities are concentrated on the development of the best practices
in the production of geostatistics in Europe.
EFGS aims at beeing a global forum and umbrella organisation from
conference in Brazil in 2014.

ESSnet GEOSTAT projects
Recommendations
1: The GEOSTAT grid dataset
…referenced to … Grid_ETRS89-LAEA…
2: … dataset should have a grid cell size of 1km².
3: … cell code example ‘1kmN2599E4695’ …
4: … Absolute counts of the statistical units
(such as number of inhabitants, households, buildings,
workplaces) should be disseminated without any
restrictions…
5: … downloaded free of charge…
6: … dataset version 1 … reference year 2006.
The next version … reference year 2011.
7: … quality … in the form of INSPIRE metadata encoded
in ISO19139 .xml files. The production process should be
documented per grid data source and country.

EFGS Recommendations
1: Datum and projection. Grid data for the European GEOSTAT dataset will be
referenced to the European Grid Grid_ETRS89-LAEA_1K.
2: Cell size.
The GEOSTAT grid dataset will have a grid cell size of
1km².
3: Cell code.
The cell code is composed of the size of the cell and the
coordinates of the lower left cell corner in ETRS89-LAEA. The cell
code "1kmN2599E4695" identifies the 1km grid cell with
coordinates of the lower left corner: Y=2599000m, X=4695000m.
4: Disclosure.
The GEOSTAT project recommends that data protection
measures should depend on the delicacy of variables. Absolute
counts of the statistical units (e.g. inhabitants, households,
buildings, workplaces) should be disseminated without any
restriction, even for the smallest grid sizes.
5: Availability.
The GEOSTAT dataset can be downloaded free of charge and
without usage restrictions in a packagage of a csv file with the
statistical data, a grid net shape file and an INSPIRE metadata file
in ISO19139 encoding. The dataset can be downloaded from the
EFGS website and from the Eurostat website.
6: Reference year.
The GEOSTAT 1A dataset version 1 will have the reference year
2006. The GEOSTAT 1B dataset will have the reference year 2011.
7: Quality and metadata. The data quality of the GEOSTAT dataset version 1 will be in the
form of INSPIRE metadata encoded in ISO19139 xml files. The
production process will be documented per grid data source and
country.

EFGS and a global vision
27th of July 2011: UN Economic and Social Council
sets up Committee on Global Geospatial Information
Building the infrastructure for the gathering, validation, compilation and dissemination of
geospatial information is … as important for countries as the building of roads and
telecommunications networks...
…UN take the lead role and serve as the coordinating entity of the global geospatial
information community, hence the decision to create the committee…
The committee is mandated, … with providing a platform for the development of effective
strategies on how to build and strengthen national capacity on geospatial information,
especially in developing countries.
… compile and disseminate best practices and experiences of national, regional and
international bodies on geospatial information related
to legal instruments, management models and technical standards, thus contributing to
the establishment of spatial data infrastructures.
The committee will comprise experts from all Member States, as well as from international
organizations, who will serve as observers.

Geographic information system
• Geographic information system (GIS) is a system
designed to capture, store, manipulate, analyze, manage,
and present all types of geographical data.
The acronym GIS is sometimes used for geographical
information science or geospatial information studies to
refer to the academic discipline or career of working with
geographic information systems.
In the simplest terms, GIS is the merging of cartography,
statistical analysis, and database technology.
