ETRS89 as reference
coordinate system for Europe
E. Brockmann
Topics
• Basis of ETRS89
• The 3 hierarchies: European – national new – national old
- availability and accuracy
- 3D
- 2D + 1D
- Country-specific situations in Europe
- some examples of Switzerland
- specifications and standards (European / national)
ETRS89 as reference coordinate system for Europe

Definition ETRS89 (=System)
• Adopted in 1990 by EUREF
• ETRS89 was aligned to the international reference
system ITRS at epoch 1989.0.
• Whereas European stations have movements of several
centimeters within one year in the ITRS, ETRS89 is fixed to
stable part of Europe
• 2003: decision of the European Commission to relate
their own geographical data to ETRS89

Station movements globally
• World-wide (1-10 cm/year)
Europe (< 1-2 mm/year)
Europe: 2.5 cm/year -> North East

EUREF
“mm”

new “cm”
National
old
“cm/dm”
• “Fixing” / Defining coordinates - High accuracies and worldwide thanks to GPS
• Need for homogeneous national reference frame in Europe
(Eurogeographics, INSPIRE, GIS data exchange): ETRF
• National ETRF coordinates were in the past mainly
computed from campaigns – today permanent networks
define national reference frames
• The ETRFyy realizations are used as the reference frame
for Europe an in the countries!
• Umbrella EUREF: EPN web portal gives detailed
information on coordinates. Coordinates are mainly
“scientific” oriented (weekly an multi-annual coordinate sets)
• In countries “old” / distorted coordinate reference systems
exist

Why 2-3 cm differences? Limits of
ETRS realizations
•
•
•
•
different ETRFYY definitions and reference epochs
transition from campaign to permanent stations
different analysis models and software used
different station setups (antenna changes) – most recent
EPN station setup was used for the comparisons
• mapping agencies cannot change coordinates frequently
• location on “non-stable plate” (South Italy)
• Well done by the national mapping agencies
• Limit: stable part of Europe

Requirement 5
INSPIRE will mandate the Lambert Azimuthal Equal Area (ETRS89-LAEA) for spatial analysis and
display
Requirement 6
NSPIRE will mandate the Lambert Conformal Conic (ETRS89-LCC) for conformal pan-European
mapping at scales smaller or equal to 1:500,000
Requirement 7
INSPIRE will mandate the Transverse Mercator (ETRS89-TMzn) for conformal pan-European
mapping at scales larger than 1:500,000

Grids (plane trafo) in other EU
countries
• At annual EUREF not a “hot” topic (no big discussions) ->
also available in the countries (but different accuracies)
• For UIC (2006) a detailed status was collected for countries
France, Germany, Netherlands, Poland, Spain, Sweden,
Switzerland - all countries have slightly different solutions,
but the goal of the transformation “old”-”new” is reached.

Advantages of ETRS
•
•
•
•
ONE reference system for Europe
Linked to the international reference system ITRS
Easily accessible with GPS
No distortions in the network / no adoption to neighbouring
points
• „Absolute“ coordinates / less maintenance work for local
reference points
• Simple handling of coordinates for users (economy,
administration, etc.)
• Enables an exchange of geographical data
