LAND AND WATER FLAGSHIP


Overview

• Data specification

• Geospatial supply chains

• The data specification framework

FSDF Data Specification Framework | Paul Box2 |


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

FSDF data specification framework


Source Make Deliver

Source: Supply-chain operations reference-model (SCOR)

Use case , requirements, gap analysis, develop spec.

- current supply data- new data sources

- Implement spec. - services - flavours - documentation



ISO 19131 Dataset - identifiable collection of dataData product – dataset (or series) that conforms to a data product specificationData 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.

• Reconcile different information models and semantics of supplied data

• Upstream use of common models reduces total downstream cost

• Modelling and standardisation underpins efficient integration

A proposed data specification framework for the FSDF



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

In conclusion…

• Increased design and production costs• conversations with users

• investment in modelling & services incl. & skills development

• Standards framework brings quality, coherence & efficiency • use cases ensure quality, fit for purpose products

• supply chain improvement - data transformation, data exchange schemas & common vocabularies

• product interoperability

• tooling support

• Reduced total ‘system’ costs
