     Interoperability in the Geosciences

“the ability of software and hardware on
  different machines from different
  vendors to share data”

   Efficiencies for government
   Efficiencies for industry
   Benefits for the wider geoscience
    community
Traditional paper map
                    Traditional Paper Maps
   Advantages
    •Presents lots of information
    •Readily understood by experts (~0.2%)
    •Targeted to specific end-users
   Disadvantages
    •Stand-alone product
    •Hard copy only
    •Allows only limited analysis
    •Doesn’t allow data exchange
    •Single legend
    •Requires further ‘explanation’
Digital Maps
                                  Digital Maps
   Advantages
    •Captures most map information
    •Human readable
    •Some data exchange capacity
    •Allows queries and analysis
   Disadvantages
    •Targeted end-user
    •Single legend
    •‘Flat’ data structure
    •Vendor specific format
    •No relationships, cross- sections, face notes
Structured Digital Data
                    Structured Digital Data
   Advantages
    •Handles all the information
    •Is well-structured
    •Allows establishing data exchange standards
    •Caters for all end-users
    •Suitable for computer analysis
    •Machine readable
   Disadvantages
    •Difficult for humans to read
    •Requires agreed standards

                           What is GeoSciML?
   machine readable GeoScience Markup
    Language
   a Geological Data Model based on real world
    concepts that represents the complexity of
    geology
   tells users what geological information goes
    where
   developed by the international scientific
    community
   builds on established standards such as GML
   uses the ISO ‘feature’ model
