An identity base for hydrographic (including man-made) objects in the real world.
-- Description --
NOTE Derived 'views' of real-world hydrographic objects are represented through specialisations in other application schemas; all representations of the same real-world object share a common geographic name or hydrographic identifier.

geographicalName |
GeographicalName |
|
A geographical name that is used to identify a hydrographic object in the real world. It provides a 'key' for implicitly associating different representations of the object.
-- Description --
EXAMPLE A standing water in a mapping view may share the same geographical name as a WFD lake in a reporting view, implying they are both representations of the same real world object. |
hydroId |
HydroIdentifier |
|
An identifier that is used to identify a hydrographic object in the real world. It provides a 'key' for implicitly associating different representations of the object.
-- Description --
NOTE 1 The identifier may be a national hydrological identification code.
NOTE 2 More than one identifier may be required, for instance a watercourse may be assigned different identifying codes under national and European schemes.
EXAMPLE A lock in a mapping view may share the same identifier as a hydro node in a network view, implying they are both representations of the same real world object. |
