Course Content

  1. An introduction to 3D computer geologic earth models, including the technical characteristics of the models, how such models are built, and the software used to visualize and manipulate models
  2. An investigation of attempts to make geophysical earth models and modeling directly compatible with geologic earth models
  3. A discussion of how to make geophysical earth modelling more interoperable with geologic earth modelling, thus facilitating closer interaction between geologists and geophysicists.
