Applying Discrete Global Grid Systems across multiple jurisdictions: lessons learned from integrating spatial and statistical data in a federated environment (Vortrag Englisch, Diskussion D/E)
Abstract: The promise of the ‘Big Data’ Era has driven us to explore new ways to integrate socio-economic and statistical data with geospatial/geoscientific data to provide new insights into both our impact on the Earth, and her systems, and their impact on us. Using conventional approaches this is a very difficult problem because we are interested in both local and global scales at the same time. Unfortunately, conventional approaches to spatial data integration are generally good at one or the other but not both; esp., when data sources span multiple jurisdictions. There is an alternative to conventional approaches in Discrete Global Grid Systems (DGGS). DGGS are Earth reference systems that use a hierarchical, equal area, tessellation of the Earth to partition and address the entire globe. DGGS enable rapid integration of spatial data from local to global scales without the difficulties and limitations associated with conventional approaches to spatial data. They are a flexible spatial data infrastructure that can be employed in either (or both) a tightly coupled and a loosely coupled fashion; thus enabling their successful implementation in heterogeneous, multi-jurisdictional settings. This presentation will provide a brief overview of the challenge of multijurisdictional integration of statistical and spatial data; an introduction to DGGS technologies; and, some lessons learned from the implementation of DGGS across multiple jurisdictions in Australia.
Short biography: Matthew Brian John Purss is a Senior Advisor on Geospatial Standards at Geoscience Australia. He is a founding co-chair of the Open Geospatial Consortium’s (OGC) Discrete Global Grid Systems Domain and Standards Working Groups. He is a geophysicist with over 20 years’ experience in the exploration, research and government sectors and holds a PhD in Exploration Geophysics from Monash University where he studied grid based approaches to magnetic and electromagnetic modelling applications. Prior to initiating and leading the international standardisation of DGGS infrastructures Matthew was instrumental in the creation and early development of the Australian Geoscience Datacube (now known as Digital Earth Australia).
