With the goal of improving 3D Data interoperability, this project group has developed the Open Mining Format (OMF), an open-source file specification to support data interchange across the entire mining community.

The first version of OMF, released in 2017, supports basic structures including points, lines, surfaces, meshes and volumes. The second version and upcoming expects to support block models, computer-generated representations of orebodies that contain valuable data about them.

Mining requires a wide range of spatial data, and new technologies are adding to their complexity. While these changes create better representations of geological phenomena, moving complex data between proprietary software formats is time-consuming and prone to error. The project will enable significant efficiency gains. 

Industry support: Four major software companies – Seequent, Dassault Systèmes, Deswik and Micromine – have publicly committed to OMF, and several others are also contributing. Read an article with the supporting companies’ comments here.
