Consolidating Canadas Geoscience Knowledge

Consolidating Canadas Geoscience Knowledge

• Peter Davenport
• Geological Survey of Canada

2
Consolidating Canadas Geoscience Knowledge

• Program intent
• Prime partnerships in preparation for a 10 year
  Cooperative Geological Mapping Strategy by
• assessing key geoscience knowledge gaps
• Consolidating Canadas geoscience knowledge
  bases, and making them accessible through the
  Internet

3
Consolidating Canadas Geoscience Knowledge

• Program elements (Strategies)
• 1. Work with provinces/territories to lay
  groundwork for Cooperative Geological Mapping
  Strategies implementation
• 2. Consolidation of ESS information and
  collaborative studies with provinces and
  territories in some priority areas as per
  Intergovernmental Geoscience Accord

4
Consolidating Canadas Geoscience Knowledge

• Outcomes
• Increased investment in geosciences for resource
  development under the Cooperative Geological
  Mapping Strategies
• Intergovernmental, multi-institutional and
  multi-sectoral partnerships in geoscience
  knowledge delivery primed for the future
• Competitive advantage in attracting exploration
  investment
• ESS, provincial and territorial geoscience
  knowledge more widely used, as definitive source

5
Consolidating Canadas Geoscience Knowledge

• Five projects under knowledge consolidation
• Geological maps and related information
• Geophysical and geochemical survey information
• Mineral and fossil fuel resource information
• Research sample collections (field to curation)
• Geoscience data repository information system
  the link to the Internet through Geoconnections
  and the Canadian Geoscience Knowledge Network
  (CGKN)

6
Geological maps and related information

• Five activities
• Bedrock Geological maps
• Surficial Geological maps
• Geological names (science language) map units,
  geological time, rock names, etc.
• Geochronology (radiometric dating)
• Paleontology

Geological map databases

• GOAL
• to deliver digital, thematic map representations
  of the geology of Canada at a variety of
  resolutions to meet the information needs of a
  wide range of users
• to link these maps to the underlying
  geochronologic and paleontological data
• i.e. to make geology maps interoperable, scalable
  and updatable with the latest research results

17
Bedrock geology map database project

• Scalability
• use different classes of map unit
• these types of map unit may not form true
  hierarchy
• source units may map to multiple parents unique
  parentage only at map polygon level, and handled
  by multiple ontologies

Conclusion

• Geological maps form the main spatial frames of
  reference for communicating geoscience
  information
• Geological maps represent conceptual 4D models,
  and the data behind them are complex in their
  relationships

34
Conclusion

• More standard terminology for the rock names is
  being developed for future mapping projects
• The terminology for the names and age of map
  units is being managed in a stratigraphic
  database to make usage more consistent

35
Conclusion

• Features and attributes are extracted from the
  maps, loaded to NADM tables, and the
  relationships implicit from the maps rebuilt
• The physical, chemical and genetic properties
  implicit in rock names are extracted to enable
  more flexible and consistent querying by these
  characteristics

36
Conclusion

• CGKN is the framework for coordinating Federal,
  Provincial and Territorial efforts to build
  national geoscience map layers
• CGKN coordinates with GeoConnections the building
  of geoscience for CGDI
