INSPIRE Conference 2010as a framework for cooperation
> Geodetic reference system includes:
• geodetic datum - a datum describing the relationship of a co-ordinate
system to the Earth (set of parameters that define the position of theorigin, the scale and orientation of a co-ordinate system and typicallyincludes an ellipsoid definition),
• vertical datum - a datum defining the zero reference surface for
heights and depths and describing the relation of gravity-related heightsto the Earth (ellipsoidal heights are referenced to the ellipsoid surfacewhereas normal heights are related to geoid surface, typically defined asa mean sea level),
• map projection - a set of mathematical rules for representing the
curved surface of the Earth on the plane surface of maps, charts andcomputer monitors (it constitutes a plane co-ordinate system typicallyvisualised as a regular grid).

> In geodesy the INSPIRE regulations refer to (but not only):
• coordinate reference system,
• geographical grid systems.

ASSUMPTIONS
> Use by all nations of identical reference systems is one of thebasic requirements to achieve interoperability of spatial data inthe European Community.
> Spatial position on or near the Earth’s surface may beunambiguously described using co-ordinates in one referencesystem (3D position) or in two geodetic reference systems:horizontal (2D position) and vertical (1D position).

POLISH REFERENCE SYSTEM
> Geodetic datum EUREF 89 derived from European Terrestrial Reference Frame ETRF 89,
> Normal heights system related to the mean Baltic Sea level, fixed on gauge at Kronstadt near Sankt Petersburg (Russia),
> Plane coordinate systems called „1992” and „2000” both based on the Conformal Transverse Mercator Projection (TM):
• co-ordinate system 1992 - used for mapping at scale 1:10,000 and smaller (one zone, CM=19o E, scale factor 0.9993, false origin: x0 = -5,300,000 m, y0 = 500,000 m),
• co-ordinate system 2000 - used for geodetic surveying and mapping at scales larger than 1:10,000 (4 zones, CM= 15o,18o,21o,24o E, scale factor 0.999923, false origin: x0 = 0 m, y0 = 500,000 m).

INSPIRE Conference 2010as a framework for cooperation
• Improvement of ETRS 89 system
performing the ASG-EUPOS calibration campaign,
integration of EUVN with gravimetric network.
• Implementation of EVRS 2007 system
adjustment of leveling measurements in UELN system,
reprocessing of geoid model.
• Implementation of recommended map projection
development of register of control points data base
FUTURE PLANS
INSPIRE Conference 2010as a framework for cooperation
• In 2009 the Polish primary leveling network has been joined with the United European Leveling Network (UELN) and it shall be together with the set of 62 EUVN points and geoid model 2001 a basis for adoption of European Vertical Reference System 2007 in Poland.
• The Polish horizontal reference system since 1992 has been integrated with European Terrestrial Reference Frame.
• ASG-EUPOS augmenting system improves geodetic reference systems realization in Poland and fulfils requirements of users for three-dimensional (3D) positioning in GIS applications.
• No legal or technical obstacles exist in Poland against implementation of the ETRS89 and EVRS07 systems.
