INSPIRE TWG OF+SR

– Introduction to the work of Sea Regions (SR) and Ocean Geographic Features (OF) TWG

• Scope and decision making process

– Informative description of Sea Regions and Ocean Geographic Features

• Examples in projects

• UML Free!

– If UML is what you are after then come to the presentation at 16:00 ‘reporting back on the drafting teams’

– What is needed now from SDIC’s and LMO’s

• Key areas where input is needed to shape the specifications

• Considerations when developing your comments

Sea Regions & Ocean Features: Starting Point

• Sea Regions (INSPIRE, 2007) Physical conditions of seas and saline water bodies divided into regions and sub-regions with common characteristics.

• Ocean Geographic Features (INSPIRE, 2007) Physical conditions of oceans (currents, salinity, wave heights, etc.).

• Need clear strong distinction between SR + OF– Support organisations involved with Inspire compliance

• Inspire specifications needs to be positioned to maximise value to both consumers and producers– Aligned with community practice on how data is generated and managed will help!

Considerations for INSPIRE Data Model Positioning

Feature Complexity

Number of Features

<KML>

S-57

• INSPIRE is positioned ‘just right’ to satisfy a large number of (not all) use cases

• An interoperability layer that is >> richer than standards such as KML

• Transformations ‘up’ are not possible or necessary

– This is the domain of community ‘intra-operability’

– These communities have an obligation to transform to the inspire interoperability layer

Defining SR + OF

– Sea Region is a defined marine area of common physical and/or chemical characteristics.

– A Sea Region will contain Ocean Geographical Features (Annex III) that represents the precise physical or chemical properties of the Sea Region.

– A Sea Region may have other properties that are not an Ocean Geographical Feature, for example bathymetry (Elevation theme - Annex II) and shipping lanes (transport theme – Annex I).

– A Sea Region will be a vector dataset and not be represented as a ‘coverage’ (ISO 19126) where as an Ocean Geographical Feature will.

– An Ocean Geographical Feature is the result of an observation or measurement process, not the process itself (which is described by an Environmental Monitoring Facility - Annex III)

Examples of Sea Regions

• “North Sea” (i.e. any common-usage named sea or ocean) A water body with an identified boundaries based on land and/or common circulation patterns around the sea.

• • “Sediment Cell” A water body where the net sediment budget is (close to) zero, typically used for coastal erosion management.

• • “Circulation Cell” A water body which is the fate for all pollutants entering the water body, typically used for coastal water quality management for example in the Water Framework Directive

• • “Seabed Area” Any area of sea characterised by common seabed coverage or depth (e.g. Dogger Bank).

• • “Exclusive EconomicZone” (UNCLOS) An administrative area recognised by the United Nations, based on the offshore extent from a low tidal boundary

Examples of Ocean Features

• An Oceanographic Geographic Feature (“Ocean Feature” or “OF”) describes the physical and chemical phenomena of a sea region (known as 'SeaArea' in the Inspire Sea Regions model).

• Some examples of Ocean Features are: – Time series of measurements of water level from a tide guage

– A gridded field of ocean colour

– A one off sea surface temperature measurement made by hand with a themometer

– An ocean climate model predicting future changes of salinity over time on a model grid.

• In each of these cases some estimation of the value of a property (water level, ocean colour, temperature, salinity) is made using some procedure. For the OF theme we directly build upon the ISO 19156 Observations & Measurements specification which already describes these relationships between the observation (or simulation) event, the observed property, the procedure used and the feature of interest.

Issues

- OF and MF are strongly coupled to EF

-MF and OF are implemented identically

-Not all MyOcean data products will fall under Inspire

- MyOcean will not deliver all data that is within scope of OF or MF

-Timing of MyOcean wrt Inspire specifications

Conclusions for Projects

• Projects like MyOcean are already implementing INSPIRE Discovery and View services

• INSPIRE Marine themes can be tested by EC Projects MyOcean (OF) and BLAST (SR).

– Given the timings of specifications release this will not be operational services, only prototype.

• Delivery should be simple transformation of existing services and may not prove anything

– More useful is for MyOcean and Blast to test other services (EMF, MyOcean and Energy Resources or Area Management for BLAST

Considerations for LMO and SDIC Review

• Sea Regions

– Most relevant theme is you involved in traditional ‘marine GIS’ and marine spatial planning

• Ocean Features

– Most relevant is you are involved with operational services and environmental reporting

• Where we need input from LMO’s and SDICS

– Code Lists. Which ones?

– Phenonema Scope

– Cross-theme review (e.g. OF+AF)

• More detail on SR and OF data models in TWG review session (16:00)
