Overview Data specification Geospatial supply chains The data specification framework 2
Why invest in product design? Not fit for purpose Doesn t work the way expect Doesn t meet users need Doesn t work well with other things Technology has moved on Costs to the user Conversations with users Scott Adams 2010 2015 He Mu and Zhang Qian Shanghai University of Engineering Science 3
FSDF data specification framework Use case, requirements, gap analysis, develop spec. Plan Source Make Deliver - current supply data - new data sources - Implement spec. - services - flavours - documentation Source: Supply-chain operations reference-model (SCOR) 4
Data Product Specification Supply Demand Dataset Implemented as Data product Data describes metadata specifies /describes Data product Specification Metadata ISO 19131 Dataset - identifiable collection of data Data product dataset (or series) that conforms to a data product specification Data product specification description of a dataset or dataset series together with additional information that will enable it to be created supplied to and used by another party. 5
Geospatial data supply chain 6
1 Point to point (anarchic) Geospatial information supply chain patterns Data sources Process* Product app. schema * find, access, extract, interpret, transform, load, integrate and harmonise & make product* 2- Centralised Data source * Make product Process* Product app. schema 3 Aggregated Aggregator Data sources Process* * extract, interpret, transform, load, integrate and harmonise product app. schema 4 - Brokered Data sources WFS WFS WFS Broker Process * * Transform (on the fly) WFS Community app. schema 5 - Federated WFS Data sources WFS WFS WFS Provider Community App. schema Intermediary End user 7

Federated geospatial supply chains Reconcile different information models and semantics of supplied data Upstream use of common models reduces total downstream cost Modelling and standardisation underpins efficient integration 9
A proposed data specification framework for the FSDF 10
Data specification framework supports the long term development and maintenance of a suite inter-related foundation data products User requirements Concepts, relationship & classifications Current data products Gap analysis - current & future state Design & implement new products 11
