EarthResourceML Background

• Information Model for Exchange - Australian Mines Atlas

• Scenarios- deliver data to Australian Mines Atlas- mineralisation investigation over an exploration lease- land use planning to aid land use decisions.- a mine site hazard study- examine mineral system potential

• Governance- Australian Government Geologists Information

Committee (GGIC)- Mineral Occurrence Task Group- Extension of GeoSciML

• Demonstration

EarthResourceML Scenarios

• an explorer conducts an investigation of mineralisation over an exploration lease

• a land use planner investigates potential resources within an area to aid land use decisions.

• a mining engineer conducts a mine site hazard study

• a project generation geologist examines mineral system potential

• deliver mineral occurrence data to the Australian geoscience mineral occurrence portal (Mines Atlas)

EarthResourceML Governance

• Australian/NZ Government Geologists Information Committee (GGIC)

• Commenced work in November 2006

• MineralOccurrences v1.0 released March 2007

• EarthResourceML v1.1 released July 2009

• Production services by GSV, PIRSA, MRT, GSWA, NTGS

• Consumed by AuScope Portal (http://portal.auscope.org/gmap.html)

• Proposed INSPIRE standard (December 2009)

• CGI-IUGS requested to take-over governance (August 2010)

Methodology

• Lessons learnt from GeoSciML development:- No right or wrong way, just agreed way- Use UML to capture model- Don’t maintain classes you don’t have to- Re-use other domain classes (GeoSciML, GML)

• Identify Use Cases from Scenarios- Required for testing

• Community standard data model - an ‘Application schema’- In a serialized form used for data transfer (i.e. ‘standard exchange format’)In general this is different from the storage format

• GoalOne normative artefact – the UML modelDocumentation generated automatically‘How to’ and ‘Cookbook’ documentation

• Map users data to model – modify model if necessary

• Establish WFS – modify model if necessary

Key points

• Describes Earth Resources independent of human activities

NiS mineral occurrence

• Caters for description of Mineral Occurrences using:

Mineral Deposit Models (e.g. remobilised NiS) Mineral Systems (Geodynamic context) Crustal processes

• Utilises GeoSciML ‣Mapped Feature to describe spatial representation‣Earth Material to describe host and associated materials
