Interoperability of Geology boreholes

• The geology profile
• Boreholes delivered by WFS according to the
  borehole XML schema and the profile
• Dictionaries
• CGI Stratigraphic chart dictionary for ages
• CGI Simple lithology dictionary
• Local dictionaries such as BRGM lithology
  dictionary
• Stratigraphic lexicon
• WFS GeoSciML geologic units

Examples of geology boreholes

• Lithology observation according to CGI simple
  lithology dictionary

GeoSciML lithology property
Sedimentary rock term from the CGI simple
lithology dictionary

Boreholes in GeoSciML tesbed 3

• Use case 2
• select geology boreholes available in a 2D
  bounding box and export them into GeoSciML
• Use case 3
• select geology boreholes with depth greater than
  ??? meters and intersecting some lithology (for
  instance, sedimentary rock defined in the CGI
  simple lithology dictionary in any language
  english, french, italian)

13
Boreholes in GeoSciML tesbed 3

• Use case 4
• import and export GeoSciML data in applications
• Applications import/export geology boreholes
  available in a 2D bounding box
• GeoSciML BRGM client it shows a summary of the
  selected borehole (lithology, geologic units)
• GDM (Geological Data Management), BRGM Windows
  application, imports geology boreholes accessed
  either from a WFS or an XML file

GDM and geology boreholes

• A strip log with observations of age and
  lithology

CGI simple lithology vocabulary
Age colored with the colors of the international
stratigraphic chart

GDM and GeoSciML boreholes

• A 3D block diagram with the foot wall and the
  hanging wall of the chalk interpolated by GDM

international stratigraphy chart

GDM and geology boreholes interoperability

• A Map with BGS geology boreholes along the
  channel tunnel and BRGM geology boreholes in the
  north of France

18
Boreholes interoperability

• More profiles can be designed
• Structural data (GeoSciML geologic structures)
• Ore grades
• Oil
• Technical data

19
Conclusion

• Data exchange based on standards
• GeoSciML geology link between boreholes and
  maps
• Applications and components to process geology
