Exploiting the UNSDI Spatial Identifier Reference Framework (SIRF) in Australia:Innovations and Policy Implications

Canberra, 20 - 22 November 2012

Overview

• Why? – project drivers• What? – the solution • Where? – Indonesia and Australia • How? – Innovations • Where next? - Policy implications

UNSDI Spatial Identifier Reference Framework | Paul Box 2 |

The problem • Large scale complex interwoven challenges • ‘Big data’ - the information tsunami • ‘Glocalisation’ • Rapid Information integration • Highly spatially & temporally variable phenomena

Over the nextdecade, the numberof "files,“ or containers for Information will grow by (source: EMC)

Gazetteer – a special case of Spatial Identifier

GAZETTEERID, placename(s), feature type, location

• Official list of names • Related to mapping process (toponymic)• Used for map lookup

• Names are ambiguous • One name – many places• One place - many names

• Australia, Australie, أستراليا• Wollongong, ‘the gong’ • Sydney, City of Sydney

Melbourne – locality – Victorian Gazetteer –Official

Melbourne – municipal council boundaries – official

Foundation spatial data themes

Spatial Identifiers – an index for SDI

• Addressing • Administrative Boundaries• Positioning• Place Names• Land parcel & Property• Imagery• Transport• Water• Elevation and Depth• Land cover

Sensor networksCell towers


• Overlap and duplication• Heterogeneity – everyone does them differently • Fragile, unreliable• Limited access mechanisms• Used out of context

• Disconnected from underlying geospatial data • Limited metadata provenance/authority

Spatial identifiers


• Infrastructure to register, link, and deliver spatial identifiers

1. Harvest spatial identifiers from geospatial data sets2. Mint identifiers and build cross-walks

3. Deliver as URI identifiers into the Linked Data Web and back to SDI (standard interfaces)

4. Users access ’Spatial Bookmarks’ & can connect back to underlying data

5. Downloaded & embedded in system to reference statistical information

Where are we SIRFing?


Innovation – the right information….

•Common reference – unambiguously reference a place using URI• Granularity - moving from dataset to feature level

– Better discover, explore, understand then download/use the bits you need


“Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/”

Innovation – delivered in the right way

• Linked data • ‘spatial bookmarks’ for the web • Interwoven feature level metadata with data - authority, licence,

• The role of spatial identifiers to link information• SI as index to underlying data in SDI • Linking multiple representations of the same real world feature • Linking information to locations across systems


Innovation – handling the social dimension

• Linking - not choosing a winner• Registering and cross walking

• Evolution not revolution• Providers – no need to change underlying business process/systems • Users – continue to use preferred SI sets• Convergence

• Building a social network graph of information resources • FOAF graph of info resources and their usage

• The power of the crowd


Key enablers – Openness

• Open data• ‘freemium’ for spatial identifiers PLUS • Links to underlying data • With various price & licence models

• Open standards• Open source software

• Open Government Indonesia• Innovating• Working with the crowd• A legislative framework


Implications for spatial policy and practice• Openness • Governance – to steer or row

• Policy (legal?) framework • Community behaviour – tin hugging, information modelling & design for

reuse • Formal and informal (VGI data sources)• Linked data - Spatial feature identifier governance

• Information custodianship and access• From supply to demand driven information • Stability and predictability - improved change management

• Engaging with the broader community• Identity not geometry
