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
•Simple data table linking each grid cell
Unique identifiercoordinatesAttributes:
Eg., slope, population, salinity…Natural/admin boundariesuser-driven, have custodians and metadata
•Spatial Queries: SQL strings GIS software

Cost Efficiencies
Inefficient cost structure– only 7% of costs in actual
productive operations– about 18% in
applications– about 75% in locating,

Data Sharing
Monitoring
Data collection & custodianship:
Current State & Trend
Data/ Standards/ Technology/ Governanceclimate, 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
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 &

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

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
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 & H2O)
– Melbourne University – resource allocation matched to socio-demographic (ABS) parameters
– GA – national land cover data management– SV & VPAC – scalability solutions
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
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
