The PEMS Demonstrator: Present and Future Tai (T.O.) Chan SII, DSE Surveying & Spatial Information Victoria 2008 Summit 17 September 2008
2
2 Overview The concept of grid cell data infrastructure Supporting governments’ data needs – Monitoring, modelling/analysing and reporting/publishing Functions Outcome of current Demonstrator Future
3
3 Simple data table linking each grid cell Unique identifier coordinates Attributes: Eg., slope, population, salinity… Natural/admin boundaries user-driven, have custodians and metadata Spatial Queries: SQL strings GIS software

5 SDI Data Utilisation Life Cycle Acquire Search Analyse Report Process Publish Design Integrate Data Technology Standards Governance
6
6 Cost Efficiencies Inefficient cost structure – only 7% of costs in actual productive operations – about 18% in applications – about 75% in locating, assembling data 'Financing the National Spatial Data Infrastructure' (US Federal Geographic Data Committee) 7% 18% 75%

7 Data Sharing Monitoring Data collection & custodianship: Current State & Trend Data/ Standards/ Technology/ Governance climate, NR, biodiversity, fire & land Management … Consistency, repeatability, transparency (audit trial), single point of truth Modelling/Analysing Data Processing: Potential change, impact & response Reporting/Policy Dev Output Reporting & Data Publishing: Strategy development, communication
8
8 Data Sharing (eg., climate change) Changes in rainfall, sea level, temperature etc. in Australia Changes in rainfall, sea level, temperature etc. in Gippsland, Victoria Impact on fire, farming systems, bio- diversity & infrastructure in Gippsland, Victoria Adaptations – what to grow/build? where? at the suburb/ paddock Data/ Standards/ Technology/ Governance scale & new data scale & new data

9 PEMS Technology
10
10 Current Use Cases Ecomarket (market-based Instrument) – EEU – data publishing & extraction Wildfire Asset Identification and Consequence Evaluation – OESC – data management/updating Management of land use data – DPI National crop productivity forecast – GA – reporting/presentation Integration with Spatial Datamart – SII – web services

19
19 Evaluation Findings - preliminary Value – Single point for data discovery and interrogation; – Significant functionality; and – Data bundling capabilities, especially in relation to data extraction. Limitations – Performance – Network connectivity – Navigation, end-to-end services and terminology – Scalability
20
20 Enhanced PEMS Demonstrator Enhanced component – production pilot – EEU – data publishing & extraction – OESC – data management & updating – OCES – data management for SOE reporting – SII – integration with Spatial Datamart More demonstration use cases – Monash University – environment monitoring (C & H 2 O) – Melbourne University – resource allocation matched to socio-demographic (ABS) parameters – GA – national land cover data management – SV & VPAC – scalability solutions
21
21 Value Propositions All Governments: – Providing standard repositories for data publishing (the national nested grid) – Accelerating and improving the quality of evidence- based policy – Overcoming issues of information flows from the states to the commonwealth – Major advantages over existing on-line GIS atlases and meta-data directories Academic & Private Sector: – Access to authoritative data for R&D and developing value added products and services
22
22 Proposed Model/Time Cash contributions from both CRCSI and key participants key participants commit to 3 years, starting April 2009 Development largely complete by March 09 Supported by CRCSI sub-committees Governing Board approval is pending
