With the goal of improving 3D Data interoperability, this project group has developed the Open Mining Format (OMF), an open-source file specification format 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 (2.0) upcoming expects to support block models, computer-generated representations of orebodies that contain valuable data about them. OMF version 2.0 is expected to be released in May of 2021.

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 OMF project will enable significant efficiency gains from lost time transferring data and put a stop to erroneous data due to improper data translation. The importance of clean, correct data is vital for mines going forward and the usage of OMF will help streamline that process so that data remains consistent and correct.

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.

March 2021 | Update

Version 2.0 steerco group developers met and identified a one month timeline for finalization of OMF version 2.0. Focus has been put on completing the Python version and thus the C++ version is now being considered as a future priority.

Jan 2021 | Update

Version 2.0 steerco group developers met to outline next steps prior to version 2.0 finalization. From this meeting came several Items, such as identifying a roadmap for OMF development and priority structure, as well as a communications plan for mines to relay the idea were discussed. 

2019 | Update

A python version was developed in 2019. Need to develop C++ version. Discussions with AWS towards supporting an open data set for OMF testing

2017 Nov | Open Mining Format V1.0 (OMF)

An open-source file specification for 3D data interchange across the mining community. This version of OMF supports basic structures including points, lines, surfaces, meshes and volumes. Visit OMF on GitHub here. Read the OMF 1.0.1 docs here.
