This video shows how to set up an inversion and is a prerequisite for watching the other how-to inversion videos listed below. The steps in this video include loading the VOXI menu, setting up a new VOXI session, and adjusting the parameters required to run an inversion. After watching this video, we recommend watching our other videos on running inversions.

In this video you’ll see how to add or modify data your model and run an unconstrained inversion.

Are you thinking of embarking on a geophysical survey? Want to do more with your data provided by your geophysical contractors? In this webinar we will demostrate a typical workflow for working with geophysical data as part of grassroots or brownfield projects.

• Easily work with data from small ground based surveys to large airborne projects.
• Quickly import and review your data from your surveys.
• Visualize your geophysical data using industry standard formats.
• Integrate the geophysical data with other earth science data (geological, geochemical, drillhole, etc).
• Easily access and incorporate publicly available datasets, to help minimize the cost of further exploration or investigations.
• Optimize the understanding of your geophysical data through applying advanced filters and other analysis tools to your data.
• Add powerful 2D and 3D visualization and specialized data modeling, compilation and interpretation functionality to your projects.
• Easily create final report-quality maps and images.

Explorers can now create sections from survey lines that contain bends or curves. View these crooked sections in 2D or 3D views as either grids or pixel plots.
 

New digitizing tools in Oasis montaj and Target 8.0 enable you to combine your expert knowledge with real data to draw accurate geological interpretations on section maps. An intuitive wireframing workflow makes it easy to build 3D subsurface geological models by joining 2D interpretation sections to create 3D wireframe bodies. Share your interpretations as geostring files and wireframing results as geosurface files.

At the 2012 PDAC Conference, Geosoft CTO Ian MacLeod announces Geosoft's new VOXI Earth Modelling cloud-based service for performing 3D inversions of Geophysical data. The VOXI service will be available to all explorers in April.

A quick overview of Geosoft products, with practical examples showing how you can use Oasis montaj in your exploration projects.

Geosoft Seeker is a tool for finding and accessing data. With the release of Oasis montaj and Target 8.0, Geosoft Seeker has been updated to be faster and more responsive, featuring a new simplified interface for searching and downloading data with your Geosoft application or plug-in.

Learn how to specify the fit error value which influences the difference between the measured and predicted data and how the inversion will fit the data.

Use this focusing constraint to improve a simple unconstrained inversion to overcome the "non-uniqueness" problem in geophysical modelling.

How to define a starting model constraint with VOXI that you can use in forward modelling or to enable an inversion to reach a faster optimal result.

Export VOXI Earth Modelling inversion results into 3D maps and databases

Use the Inversion Journal to keep notes on different inversion sessions as a reference 

Introduce the VOXI Viewer environment -- the location of useful tools and how to manipulate the project view

Geosoft VOXI Earth Modelling enables you to quickly generate a 3D voxel model from your gravity and magnetic data using inversion or forward modelling. This video will show you what VOXI is and how it works.

Learn how to create a custom map template that you can use to quickly generate other maps. 

This presentation describes the misalignment between the current mineral industry practice and the future mineral and resource needs of society. Meeting these needs will requiring a fundamental shift how the mineral industry does their exploration targeting. Exploration will need to shift from looking at longer life but increasingly lower grade and high energy consumption brownfield deposits to seeking higher quality greenfield deposits. Finding new mineral districts, particularly those in areas of challenging cover, will require innovations in both technology and understanding mineral systems on a greater scale.

Presented by Prof. Campbell McCuaig, Director of the Centre for Exploration Targeting (CET) at the University of Western Australia.

An overview of the new geology and subsurface features in Target 7.5 and Target for ArcGIS 3.5.

Learn how to use scripts to automate repetitive tasks and create custom workflows.

Presented by Birgit Woods. Find out how you can effectively organize, validate, process and visualize your geochemical data without leaving your ArcGIS environment. Also learn what's new for Geochemistry for ArcGIS 2.0.

In this seminar you will learn about:

• Maintaining data in an ESRI file geodatabase using a data model optimized for geochemical data.
• Using the merge reports to identify samples that are missing location or assay information.
• Simplify the quality control process with easy to use standard and duplicate handling and graphing capabilities.
• Leveling Data options based on a categorization field such as lithology.
• Analyze multi-element geochemistry data using interactive multiple histogram plots (now in colour), Pearson’s correlation reports, scatter plots, probability plots (multi now in colour), ternary plots and box plots, to identify outliers and define populations.
• New Box plot options including log distribution and whisker display to identify outliers.
• Select and subset data interactively from maps based on rock codes, regions or map groups.
• Grid and contour geochemical assay point data to enhance data display.
• New 3D capabilities (3D Topography draping).

Learn how you can use Target for ArcGIS to process large volume surface and drillhole data with ease and generate professional-quality maps for presentation.

This online seminar includes time-saving tips for making your workflow more efficient in Oasis montaj. Topics include shortcut keys, map snapshots, recording scripts and creating custom menus to automate your workflow.

Quick shortcuts and tips that you can use to make your work easier in Oasis montaj. Topics include: drag and drop importing, hotkey shortcuts, drag and drop grids into maps, pasting graphics and text, and helpful default settings.

Geosoft's Chief Technologist, Ian MacLeod presented this talk, VOXI: A Cloud approach to earth modelling for exploration, during the PDAC 2012 conference & exhibition in Toronto, Canada as part of the PDAC Geophysics workshop series. This presentation describes the problems of complexity while harnessing the power and global availability of cloud computing. Geosoft's goal has been to make 3D geophysical inversion practical and accessible to more explorers and exploration problems thereby improving exploration success. http://www.geosoft.com/voxi

A repeat of the VOXI presentation given at Geosoft's booth at PDAC 2012 by Ian MacLeod and Elizabeth Baranyi. This video explains what VOXI Earth Modelling is and how it works. Elizabeth provides a real-time demonstration of how to prepare and run an inversion in VOXI using data from the Podolsky property in Sudbury.

In this online seminar you will be introduced to the VOXI Earth Modelling interface and functionality. Instructors (Robert Ellis and Elizabeth Baranyi) will demonstrate how you can use VOXI Earth Modelling as a part of your workflow in the Oasis montaj environment. Learn how to set up and run a simple inversion.

This seminar will walk you through the steps of confining the property of a 3D volume to a user-defined range and then comparing the outcome to unconstrained 3D inversion results.

This video demonstrates three new interconnected features in Target for ArcGIS 3.5 that make working with 2D and 3D data in plan and section maps easier.
