What is Testbed 2?
 It demonstrates delivery of Geological Data using:
 Web Feature Services (WFS)
 Web Mapping Services (WMS)
 Web Coverage Services (WCS)
 Based on international standards (ISO, OGC)
 GeoScience Mark-up Language (GeoSciML)
 GeoSciML is a Geography Markup Language (GML)
schema for sharing geological information
GeoScience Markup Language (GeoSciML)
Brief History
 Developed under IUGS Commission for the Management
and Application of Geoscience Information (CGI)
 November 2003 ‘in principal’ support from 15 countries
 November 2004 six surveys established procedures
(USA, Canada, UK, Japan, Arizona, Victoria and CSIRO)
 September 2006 Testbed 2 released and endorsed by
22 surveys from 15 countries
 Accepted as geological data exchange standard by all
Australian jurisdictions
 Proposed European INSPIRE standard for geological data
 World 1:1 Million geology map (2008-2012)
GeoScience Markup Language (GeoSciML)
Current activities
 Design Task Group (Bruce Simons – Chair):
 Design GeoSciML as a Geography Markup Language
(GML) schema for sharing geological information
 Testbed Task Group (Alistair Ritchie):
 Demonstrate GeoSciML using Web Feature and Web Mapping
Services
 Service Architecture Task Group:
 Develop the formal architecture required to implement services
that deliver the use cases
 Content Task Group (Linda Bibby):
 Design the vocabulary (content) services that meet the schema
requirements

One service – many uses
GML-based data can be ….
Rendered into a
queryable map …
… formatted into a
report or ….
Condition: community-standard data model/encoding
… read and used by any
WFS/GML enabled application
Why?
Minerals Exploration Action Agenda
Pre-competitive Geoscience Strategy
“Governments in consultation with industry, to develop and
implement nation-wide protocols, standards and systems
that provide internet-based access to, and effective storage
and archiving of geoscience datasets and industrygenerated exploration data”

Remember:
 Service not designed to work with any specific
software package (eg ESRI)
 Uses open community defined standards (ISO,
OpenGIS)
 Uses a rich scientific data model (eg GeoDATA.Vic)
 Complex Feature GML 3.1
 Not “traditional” flat GIS data structures
 About exchange of data (not use of data)
USE CASE ONE
Get Feature Information
 Display map
 Query one feature (a geometry)
 Return attributes in GeoSciML format
 Bonus - Return attributes as “pretty” HTML
formatted GeoSciML

USE CASE TWO
GeoSciML Data Download
 Display map
 Select several features
 Return attributes of the selected features as
GeoSciML file for download
USE CASE THREE
Thematic Mapping
 Reclassify map features based on
 Lithology
 Geological Age
 Essentially produce two thematic maps
OTHER WORK
Boreholes (from Testbed 1)
 Developed by UK (BGS) and France (BRGM)
 Delivery of Boreholes data
OTHER WORK
Boreholes – BRGM Client
 Display Boreholes points from WFS
 Select Borehole
 Display borehole attributes as:
 GeoSciML/XMML
 “Pretty” HTML based on GeoSciML
 Graphic Log based on GeoSciML
Conclusions
 Australian geological surveys have specified GeoSciML
as the geoscience data exchange standard
 MPD is committed to delivering this data using web
services
 Immediate national and international uses will be:
 Global 1:1 Million geology map
 Solid Earth & Environment GRID (SeeGRID)
 INSPIRE
 Gold Undercover (Growing Victoria – Provincial Statement)
funding development of services and infrastructure
