GOCAD Mining Suite (or simply GOCAD) is integrated, quantitative, multidisciplinary 3D geological modelling software for the mining industry.

History

It was first released in September 1999 under the name Mira Links by Mira Geoscience Limited. The GOCAD platform originated from the GOCAD Research Consortium, started in 1989 at the École Nationale Superieure de Geologie (ENSG) in Nancy, France.[1]. GOCAD was commercialized and became the leading commercial product of Earth Decision Sciences, acquired by Paradigm Geophysical in 2006. Paradigm was acquired by Emerson in 2017.

Product

GOCAD Mining Suite is an extension of SKUA-GOCAD™-- Emerson Paradigm Holding LLC. The software is written in C++. It provides its own command language (GOCAD CLI) which integrates with both TCL and JavaScript, making it possible for the end users to write and execute custom scripts within the application. Several algorithms are optimized for multi-processors and GPU. Versions of GOCAD Mining Suite are licensed as a standalone product or network modularized software. Licences can be node-locked, floating from a licence server, or attached to a dongle.

The software offers geological interpretation and validation for the creation of models that match geological concepts and honour all available data. It uses two technologies from Paradigm B.V., for creating and editing 3D geological models: Discrete Smooth Interpolation (DSI)[2],[3] and UVT Transform® [4]

Features

From data import to exploration drillhole design, geoscientists can manage their project from one central software application, providing a Common Earth Model[5] consistent with geodata[6]. It has a workflow-based interface for geologic characterization[7]. It has a 3D-GIS query environment, visualization, and a focus on data organization for investigative modelling [8],[9],[10]. It enables geologic modelling (wireframe), block modelling, and property modelling. It provides connections to geologically constrained geophysical modelling and inversion[11], [12], multi-disciplinary 3D exploration targeting[13], exploratory and geochemical data analysis, and geotechnical hazard assessment and monitoring.
