~1990 digital cartography
1994 web mapping emerges
2005 first interoperability test bed
• Most geological data exchange has
been based on local data bases which
were designed to support cartography
• Proprietary Formats
• No standards, so difficult to merge
data sets from different agencies

OneGeology is more than a digital map…..
• Data conform to generic ISO/OGC
standards (GML, WMS and WFS)
• Uses GeoSciML: a standard
information exchange model and
encoding for geoscience data
• Each Geological Survey maps from
their private schema to the
standard
• Each Geological Survey keeps its
own internal data structures
• OneGeology is not just about maps
(WMS): it is moving to unlock the
data behind the maps (WFS)

What Geological Surveys need to be aware of
• OneGeology Level 1 requires ISO compliant
metadata and basic information infrastructure
• OneGeology Level 2 requires a more mature
information infrastructure with
– Master Data Management plans
– Data product specifications (eg ISO 19131)
– A formal governance structure including vocabularies
• Demands of WFS can expose limitations in
existing information systems

OneGeology: opportunities arising
• Geological data are in a single standardised
format from any OneGeology participant
• Standardised data reduces the barrier to data
integration
• Standardised data encourages development of
tools for analysis and modelling applications
• Tools can be implemented as services: they do
not need to be installed by each user

A Key Benefit of OneGeology
• Accessible data in standardised formats allows
sensible, but ambitious software planning

80+ Countries only need
1 Portal
and a few tools
2D map service
3D model service
Fluid modelling service

Beyond Geological Maps ………….
Earth System Science
•
•
A wide range of multidisciplinary
fields of research augment
classical Earth Science today;
geosphere-biosphere-cryosphereatmosphere interactions are
particularly important.
The 33rd IGC programme
highlights the need to promote
interaction and integration of the
Earth Sciences.

Interaction and Integration of Earth Science data
•
Similar international initiatives to OneGeology
in other domains
– topographic, water, marine and climate domains
– same technology framework as OneGeology
•
GML, WMS, WFS, Catalog Services, etc
– OneGeology will integrate with these domains
•
Integration of Earth Science data with other
scientific domains will enable transnational
research to solve global issues such as climate
change and sustainable resource utilisation

Summary
• OneGeology leads a major transition in data delivery for
Geological Surveys
• The advantages are that
– Geoscience data will be made more easily accessible
– The latest versions of that data can be dynamically accessed
– More tools available (some as services) to process these
standardised data
– We will be able to tackle transnational issues such as climate
change and resource utilisation
• To take full advantage of Internet 2.0, data custodians
must ensure their data can map to standards
• This will depend on good internal governance
