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

The map sheet Map polygons

and lines, describedby GML geometries
