Motivation
International geologic map data interoperability
 availability of technologies for open geospatial standards (OGC, ISO)
 commitment to these standards by many national data providers
 international collaboration initiated in Edinburgh 2003, under IUGS-CGI

Goals of IUGS-CGI Interoperability Workgroup
Geologic map data schematic interoperability
 develop a standard GML schema for data transfer in WFS and WMS
 conduct a multi-country testbed
 demonstrate the need for transfer standards for data content

Scope: information required for production and
maintenance of geologic maps
Mapped Features
 units, structures
GeoSciML v1.1
(testbed)
Legend
 unit description
 stratigraphic column, other classifications
 Geologic timescales
GeoSciML v2
Borehole data
Field observations & measurements
 structure measurements, material descriptions …
Lab measurements
 geochem, geochronology
Precursors
NADM – US/Canada
 geologic instances and classifications – UML
BRGM – France
 Boreholes, solid geology
BGS – DGSM – UK
 3D geology
XMML - eXploration and Mining Markup Language
 Mineral exploration data – GML

Modelling methodology
1. Design using pictures
•
UML class diagrams
•
adopt and adapt existing & external standards, influence if possible
2. Prove it with Code
•
Use sample XML documents to test the model as you go
3. Generate code (XML Schema) automatically
•
maintain the model using the diagrams, not the validation tooling
Compliant with ISO/TC 211
& Open Geospatial Consortium standards

AbstractFeature
Testbed results
Use-case 1: query feature

Query one map feature (e.g. a geologic unit) and return GeoSciML
Testbed results
Use-case 2: download features

Download map features in view as GeoSciML
Testbed results
Use-case 3: re-classify features

Use standard legend (symbols, terms) for rock types and ages

IUGS Mandate
“Regular” meetings
 Edinburgh, 2003
 Ottawa, Perth, 2004
 Ottawa, 2005
 Orleans, Bruxelles, 2006
New participants added
 GA, BRGM, SGU in 2006
Web collaboration tools
Interoperability Testbeds
 includes COTS software
 industry partnerships
Status and future plans
GeoSciML v1.1 – for 2006 testbed
GeoSciML v2.0 – work already commenced
Documentation – 2006/07
 will include conformance tests to assist procurement guidelines, and as guide to
software developers
 to be submitted for formal adoption by IUGS
Vocabulary standardization
 GeoSciML provides “structural” information model to house information
 for full interoperability, property value-spaces must also be harmonized
Portals and Registries
 support discovery, service-chain composition
