without an appreciable tidal range, in open oceans and effectively in waters that are deeper<br />
than 200 m, the depth of the sea floor shall be referenced to the Mean Sea Level<br />
<strong>–</strong> For the vertical comp<strong>on</strong>ent measuring depths above the sea floor in the free ocean, barometric<br />
pressure shall be used<br />
<strong>–</strong> For the vertical comp<strong>on</strong>ent in the free atmosphere, barometric pressure, c<strong>on</strong>verted to height<br />
using ISO 2533:1975 Internati<strong>on</strong>al Standard Atmosphere shall be used<br />
6.1.3 Display<br />
IR Requirement 17 For the display of the <strong>INSPIRE</strong> spatial data sets with the View Service<br />
specified in D003152/02 <strong>Draft</strong> Commissi<strong>on</strong> Regulati<strong>on</strong> implementing Directive<br />
2007/2/EC of the European Parliament and of the Council as regards Network<br />
Services, at least the two dimensi<strong>on</strong>al geodetic coordinate system shall be made<br />
available.<br />
6.1.4 Identifiers for coordinate reference systems<br />
IR Requirement 18 For referring to the n<strong>on</strong>-compound coordinate reference systems listed<br />
in this Secti<strong>on</strong>, the identifiers listed below shall be used.<br />
For referring to a compound coordinate reference system, an identifier<br />
composed of the identifier of the horiz<strong>on</strong>tal comp<strong>on</strong>ent, followed by a slash (/),<br />
followed by the identifier of the vertical comp<strong>on</strong>ent, shall be used.<br />
- ETRS89-XYZ for Cartesian coordinates in ETRS89<br />
- ETRS89-GRS80h for three-dimensi<strong>on</strong>al geodetic coordinates in ETRS89 <strong>on</strong> the GRS80 ellipsoid<br />
- ETRS89-GRS80 for two-dimensi<strong>on</strong>al geodetic coordinates in ETRS89 <strong>on</strong> the GRS80<br />
- EVRS for height in EVRS<br />
- LAT for depth of the sea floor, where there is an appreciable tidal range<br />
- MSL for depth of the sea floor, in marine areas without an appreciable tidal range, in open oceans<br />
and effectively in waters that are deeper than 200m<br />
- ISA for pressure coordinate in the free atmosphere<br />
- PFO for Pressure coordinate in the free ocean<br />
- ETRS89-LAEA for ETRS89 coordinates projected into plane coordinates by the Lambert Azimuthal<br />
Equal Area projecti<strong>on</strong><br />
- ETRS89-LCC for ETRS89 coordinates projected into plane coordinates by the Lambert C<strong>on</strong>formal<br />
C<strong>on</strong>ic projecti<strong>on</strong><br />
- ETRS89-TMzn for ETRS89 coordinates projected into plane coordinates by the Transverse<br />
Mercator projecti<strong>on</strong><br />
6.2 Temporal reference system<br />
IR Requirement 19 The Gregorian Calendar shall be used for as a reference system for date<br />
values, and the Universal Time Coordinated (UTC) or the local time including the<br />
time z<strong>on</strong>e as an offset from UTC shall be used as a reference system for time<br />
values.<br />
6.3 Theme-specific requirements and recommendati<strong>on</strong>s <strong>on</strong><br />
