The integration of multidisciplinary geoscience data sets and creation of
3d geomodels is an evolutionary step in geosciences. Gocad is
a geomodeling software which allows to honor heterogeneous data such as sampling data and geophysical models
for the creation of complex 3d geomodels. This is facilitated particularly by a discrete
topological data model and the unique Discrete
Smooth Interpolation method.
3d geomodels are used for many purposes, for example:
- in economic/petroleum geology for quantitative reserve estimation and risk assessment,
- in tectonics for models of the earth crust at different scales, 3d balanced restoration, earth quake research
- in hydrogeology as input model for flow modelling, for modelling contaminations,
- or in general for visualization and communication among geoscientists.
The fundamental concepts and prototypes are being developed by the Gocad
Research Group (GRG) headed by Prof. Mallet and Prof. Caumon at the ENSG Nancy/ France.
A recommended reference is the book "Geomodeling".
We collaborate with
the GRG for example during joint PhD
projects (M. Apel, T. Frank).
Since 1997 Gocad is used here in Freiberg very intensively for research
and teaching.
Gocad is available from Earth
Decision/ Houston and Mira
Geoscience/Montreal (for the mining industry).
