Georeference Online Ltd's MineMatch system for the description and comparison of mineral deposits and deposit models is built on a sophisticated ontology which incorporates many taxonomies, a number of partonomies, the explicit management of negation, and fuzzy and exact descriptions of concepts.

Georeference Online Ltd is working with a large governmental geological survey to develop an ontology for describing landslides.  Please contact us if you are interested in collaborating in this project, which is multi-national in scope.

Georeference Online Ltd is working with a large national research agency to develop an ontology for describing and comparing plutons.  This work will soon be extended to the description and study of geological terranes.  Please contact us if you are aware of any existing taxonomies or ontologies that may be relevant to this project.
