Session structureSession structure

• Introduction KA• introduction of CGMW thoughts Jean-Paul Cadet,

President of CGMW• Talk about the realities of building a harmonised 1 : 5 M spatial

db of a continent • inventory of existing 1 : 5 M continental maps and spatial

databases and their formats• preconditions –or what do we need • technical issues converting he data to GeoSciML (Time Duffy)• IPR, copyright, ownership issues• Resources needed: budget, staff, hard-and software• Management, organisation and structure of the project• action and time plan

Harmonisation or interoperability?

That‘s the question

Harmonisation or interoperability?

That‘s the question



Harmonised geology dataHarmonised geology data

• an attempt of a definition• „The process by which different characterisations

and/or representations are being unified“• harmonised data e.g. have = the same data model,

same descriptions and definitions for ALL data• example: IGME 5000

time/effort• 12 years for one continent, about 30 years of staff

effort, 1, 8 M Euro

Interoperable geology dataInteroperable geology data• „The ability of two or more systems to exchange

information and use the information that has been exchanged (Institute of Electrical and Electronical Engineers, IEEE: Standard Computer Dictionary: A compilation of IEEE Standard Computer Glossaries, New York, NY: 1990

• interoperable data are e.g. comparable but not similar, definitions, data models and descriptions may differ (and mostly will be)

• no geometric Abgleich (adaptation, weeding ofmismatches?)

• can remain in their original databases but will be connected with each other

• Example (Tim Duffy ocean floor)

time/effort translation to WMS and/or GeosciML ????



preconditions – or what do we need for a global 1 : 5 geological data harmonizationpreconditions – or what do we need for a global 1 : 5 geological data harmonization

• Dedicated people (!!!!)Common … and agreed …• topography

Is there a global spatial „topographic“ dataset in 1 : 5 M similar to he 1 :1 Million global map

• data model, term dictionaries, hierarchies• project language (English, Chinese, French, German?)• Implementation specifications,

i.e. Guidelines how to do it“• scientific review system• management, project leader, working groups …• funding



preconditions – or what do we need for a global 1: 5 M geological data interoperability preconditions – or what do we need for a global 1: 5 M geological data interoperability

• Dedicated people (!!!!)Common … and agreed

• topographyIs there a 1 : 5 M global spatial „topographic“ dataset ?

• agree to use a conceptual data model for data exchange, approved by the internatiional Geocommunity (IUGS) (as ML = GeoSciML)

• language (English, Chinese, French, German?)• Implementation specifications, i.e. guidelines how to

do it“• Funding• a technical tool to make the data interoperable
