An area of sea defined according to its physical and chemical characteristics. It may have multiple geometries (extent) to represent different tidal states.
-- Description --
A SeaArea is a type of HydroObject as described in the Annex1 theme Hydrography. It has geometry described by one or more GM_MultiSurfaces. Multiple geometries are allowed to enable a SeaArea to be described according to different tidal states.
Typically however, specialisations of SeaArea will restrict the geometry to a particular tidal state or set of tidal states. SeaAreas include named seas such as ‘Baltic Sea’ and also un-named areas of sea that have particular chemical and physical characteristics. SeaAreas are 2D objects and carry no explicit information about the depth of the sea, this is specified in the INSPIRE Elevation Theme.

"External object identifier of the spatial object.".
-- Description --
"An external object identifier is a unique object identifier published by the responsible body, which may be used by external applications to reference the spatial object. The identifier is an identifier of the spatial object, not an identifier of the real-world phenomenon.". |
| seaAreaType |
SeaAreaTypeClassificationValue |
|
Type of the sea area according to the classifications in the SeaAreaTypeClassificationValue codelist. e.g. Estuary |
| extent |
MarineExtent |
|
The extent of the Sea Area at a particular tidal state. |
| parameterValue |
ParameterValuePair |
|
A value of some parameter assigned to the SeaArea. E.g. Annual Mean Sea Surface Temperature = 12 degrees Celsius
-- Description --
A SeaArea may be attributed with any number of values that are relevant for the sea area polygon as a whole. More detailed observations, such as grids and point data are the subject of the Oceanographic Geographical Features specification. |
| beginLifespanVersion |
DateTime |
|
Date and time at which this version of the spatial object was inserted or changed in the spatial data set. |
| endLifespanVersion |
DateTime |
|
Date and time at which this version of the spatial object was superseded or retired in the spatial data set. |
