Transcription

1 LAND AND WATER FLAGSHIP Standards based data specification framework for the Foundation Spatial Data Framework (FSDF) Locate 15 Brisbane March 2015 Paul Box, Bruce Simons, Simon J D Cox, & Jonathan Yu

2 Overview Data specification Geospatial supply chains The data specification framework 2

3 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 He Mu and Zhang Qian Shanghai University of Engineering Science 3

4 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

5 Data Product Specification Supply Demand Dataset Implemented as Data product Data describes metadata specifies /describes Data product Specification Metadata ISO 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

6 Geospatial data supply chain 6

7 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

Estimated FTE: 760 Source: ANZLIC Secretariat User costs Proportion of effort User Intermediaty Provider Total cost to the economy (production & use) 1 anarchic 2 Centralised 3 Aggregated Supply chain patterns 4 Brokered 5 Federated Increasing no. of users 1.

9 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

10 A proposed data specification framework for the FSDF 10

11 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

18 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 18
