Metadata for 3D Geological Models: Definition and Implementation

Etienne Taffoureau, Christelle Loiselet

Abstract


BRGM (the French geological survey) is France's reference
public institution for Earth Science applications which works on management and
delivering geosciences data to be used for helps to decision-making for spatial
planning, mineral prospecting, groundwater prospecting and protection, pollution
control, natural risk prevention and the characterization of local areas. Some
of this data are produced from 3D geological modelling which is now a classical
tool to better constrain geometries of complex geological systems and provide a
continuous description of the subsurface out of sparse and indirect data. We
propose a metadata profile compliant with the INSPIRE Directive to describe 3D
geological models and their representation.
