Steven Ramage: THE LANGUAGE OF BUSINESS

The document discusses the importance of using consistent language and terminology when communicating about geospatial data and spatial data infrastructures. It notes that as data volumes increase, having a shared understanding of concepts and their meanings through formal definitions and ontologies becomes crucial for enabling data integration and transformation while maintaining quality. Rules-based approaches can help provide this semantic consistency needed for different stakeholders to effectively discuss and work with spatial data.
Steven Ramage: THE LANGUAGE OF BUSINESS
- 1. Do we all speak the same language (or something similar)? THE LANGUAGE OF BUSINESS
- 3. THE LANGUAGE OF BUSINESS Who are we communicating with? Do we understand their needs? What are we trying to achieve? Is there consensus and agreed scope?
- 4. Is it important that we all use the same language? You say potato, I say potahto Spatial, geospatial, digital geographic information, geoinformation, location based services, volunteered geographic information THE LANGUAGE OF BUSINESS
- 5. THE LANGUAGE OF BUSINESS TLAs to SLAs SIG – French for GIS or a Special Interest Group? VGI BSI, CEN, OGC, ISO WFS, WMS, WPS SDI, NSDI, GSDI UML, XML, GML, KML
- 6. Search results for SDI = 8,960,000 in Google Ranging from the Steel Deck Institute to Scottish Development International to Silt Density Index and Spatial Data Infrastructures Requires context THE LANGUAGE OF BUSINESS
- 7. What is context? It requires shared vocabulary of the same concept/domain Through ontologies? Formal concept to model a domain/classify data Type of objects that exist together with relationships and properties THE LANGUAGE OF BUSINESS
- 8. Highway, motorway, autobahn, autoroute Engineering context? Concrete, tarmac, foundations Transport context? Number of lanes, direction of flow THE LANGUAGE OF BUSINESS
- 9. Within context what is meaning? Highway, motorway, autobahn, autoroute, autostrada Are these the same things? What defines a motorway? Connected chunks of roads, same direction flow, same name or number, M25, M4 THE LANGUAGE OF BUSINESS
- 10. Need to use motorway in a consistent manner This requires semantics – understanding data meaning Rules-based languages help Modelling - OCL, UML, SWRL SQUIRL- Spatial Quality and Integration Rules Language THE LANGUAGE OF BUSINESS
- 11. Rules help with consistency Provide common understanding There are data consistency implications for the UK Location Programme INSPIRE classifications provide some examples THE LANGUAGE OF BUSINESS
- 12. A hydrographical node transforms from code “1” (‘source’ in EA data) to value “spring” in INSPIRE Code “3” (‘junction’ in EA data) to the value “bifurcation” or “confluence” in INSPIRE (depends on how many rivers connected to it, how many flowing in and out.) THE LANGUAGE OF BUSINESS
- 13. Based on work across several INSPIRE themes these mappings are important Ensures the local schema can be mapped ‘as is’ against the INSPIRE data specifications Necessary during schema transformation and quality validation operations THE LANGUAGE OF BUSINESS
- 14. THE LANGUAGE OF BUSINESS As the volume of data increases exponentially it is becoming more and more important that we all speak the same language This has a major effect on the ability to integrate and transform data from a quality perspective It will also save time, money and reduce conflict or frustration
- 15. THE LANGUAGE OF BUSINESS We speak your language if you need solutions for geospatial data integration, transformation and quality control 1Spatial: unlocking data, empowering business
