Scope (of Motiive) –How do you apply ISO/OGC Standards to the coastal/marine community Land:sea interaction (Marine Overlays on Topology) –What do the standards look like and how does a ‘cost benefit’ manifest itself –Work with RISE

Jane’s current concern is to investigate sediment transport and coastal erosion in the UK’s Thames estuary. Jane is working in an era of a harmonised spatial data infrastructure and is able to access on-demand a range of data across the internet. Jane wishes to evaluate a variety of tidal models available to her by validating against historical tide gauge measurements. Helga (NO) and Willem (NL) both run tidal models and wish to make their datasets available for re-use – they employ standards-based interoperable web services for this purpose, and these are amongst the datasets available to Jane for evaluation. Data from the selected model is used to generate plots of current and other tidal parameters. None of the data suppliers provide dedicated portrayal services for their data, but a third-party portrayal service is available for a range of compatible ‘base’ feature types. Moreover, another service provides feature-type transformation (defined as an operation on the source feature type) to facilitate direct model-observation inter-comparison. Generic community needs to use data in a unambiguous way Clear definitions of what data sets ‘are’ =>Clear declaration of Feature Types Clear ‘use’ of datasets =>Operations on Feature Types (binding to services)

At the core of the model is a geospatial Dataset. A Dataset contains Feature instances and related objects, and is described by Metadata. Feature type definitions may be stored for re- use in feature catalogues (ISO 19110). Geographic information services operate on a Dataset, while the logical structure and semantic content of a Dataset is described through an Application schema

Since features encapsulate important data semantics within communities of practice. –Feature Type Catalogues may be regarded as ‘semantics repositories’ within an overall information architecture.
