1.1. Definitions

In addition to the definitions set out in Article 2, the following definitions shall apply:

—	‘coordinate system’ means a set of mathematical rules for specifying how coordinates are to be assigned to points, in accordance with EN ISO 19111,

—	‘coordinate reference system’ means a coordinate system which is related to the real world by a datum, in accordance with EN ISO 19111. This definition includes coordinate systems based on geodetic or Cartesian coordinates and coordinate systems based on map projections.

1.	Other coordinate reference systems may be specified for specific spatial data themes in this Annex.

2.	For regions outside of continental Europe, Member States may define suitable coordinate reference systems.

The geodetic codes and parameters needed to describe these coordinate reference systems and to allow conversion and transformation operations shall be documented and an identifier shall be created, according to EN ISO 19111 and ISO 19127.

2.2. Grids

The grid specified in section 2.2.1 shall be used in INSPIRE, unless one of the conditions specified in section 2.2.2 holds.

2.2.1. Grid for pan-European spatial analysis and reporting

The grid defined in this Section shall be used as a geo-referencing framework where grids with fixed and unambiguously defined locations of equal-area grid cells are required.

The grid is based on the ETRS89 Lambert Azimuthal Equal Area (ETRS89-LAEA) coordinate reference system with the centre of the projection at the point 52° N, 10° E and false easting: x0 = 4 321 000 m, false northing: y0 = 3 210 000 m.

The origin of the grid coincides with the false origin of the ETRS89-LAEA coordinate reference system (x=0, y=0).

Grid points of grids based on ETRS89-LAEA shall coincide with grid points of the grid.

The grid is hierarchical, with resolutions of 1m, 10m, 100m, 1 000m, 10 000m and 100 000m.

The grid orientation is south-north, west-east.

The grid is designated as Grid_ETRS89-LAEA. For identification of an individual resolution level the cell size in metres is appended.

The reference point of a grid cell shall be the lower left corner of the grid cell.

For the unambiguous referencing and identification of a grid cell, the cell code composed of the size of the cell and the coordinates of the lower left cell corner in ETRS89-LAEA shall be used. The cell size shall be denoted in metres (‘m’) for cell sizes up to 100m or kilometres (‘km’) for cell sizes of 1 000m and above. Values for northing and easting shall be divided by 10n, where n is the number of trailing zeros in the cell size value.

2.2.2. Other Grids

Exceptions, where other grids than that specified in section 2.2.1 may be used, are:

1.	Other grids may be specified for specific spatial data themes in this Annex. In this case, data exchanged using such a theme-specific grid shall use standards in which the grid definition is either included with the data, or linked by reference.

For grid referencing in regions outside of continental Europe Member States may define their own grid based on a geodetic coordinate reference system compliant with ITRS and a Lambert Azimuthal Equal Area projection, following the same principles as laid down for the grid specified in section 2.2.1. In this case, an identifier for the coordinate reference system shall be created.

8.7. Theme-specific Requirements

8.7.1. Consistency between spatial data sets

Hydrography links, centrelines and nodes shall always be located within the extent of the area representation of the same object.

Connectivity between hydrographic networks across state borders and – where applicable – also across regional borders (and data sets) within Member States shall be established and maintained by the respective authorities, using the cross-border connectivity mechanisms provided by the NetworkConnection type.

All attribution of objects in this schema shall be the same as the equivalent property of that object used for reporting obligations under Directive 2000/60/EC.

8.7.2. Identifier management

If a geographical name is used as a unique hydrologic ID for an object in this specification then it shall be derived, where possible, from a pan-European Gazetteer or another authoritative, pan-European source.

The localId attribute of the external object identifier of a spatial object shall be the same as the ID used for reporting obligations under Directive 2000/60/EC.

8.7.3. Modelling of object references

If the same real world object in a data set is exchanged using spatial objects from more than one of the Hydrography application schemas then these spatial objects shall carry either the same, unique, geographical name or the same hydrographic thematic identifier.

When linear referencing is used in hydrographic Network data, the position of referenced properties on links and link sequences shall be expressed as distances measured along the supplied geometry of the underlying link object(s).

8.7.4. Geometry representation

If spatial objects are provided at different spatial resolutions, the spatial resolution must be specified for each spatial object using the levelOfDetail attribute where applicable.

Watercourse links shall intersect wherever a connection exists between the real world phenomena they represent. No intersections shall be created at crossing network elements when it is not possible for water to pass from one element to another.

The geometry shall be the same as the geometry used for reporting obligations under Directive 2000/60/EC.

8.7.5. Use of the DelineationKnown Attribute

The attribute delineationKnown shall not be used to indicate that the accuracy / precision of a certain geometry is low; this indication should be given using the appropriate data quality element(s).

The attribute delineationKnown shall not be used to indicate a change of geometry over time where this change of geometry is known.

8.7.6. Centrelines

The centrelines of watercourse objects shall fall within the extent of the physical real world object that they represent if the Watercourse Link is indicated as not being ‘fictitious’.

8.7.7. Ensuring Network Connectivity

Wherever a connection exists in a hydrographic network, all connected link ends and the optional node that take part in this connection have to be positioned at a distance of less than the connectivity tolerance from each other.

Link ends and nodes that are not connected shall always be separated by a distance that is greater than the connectivity tolerance.
