Intrepid 6.2 – Intrepid3D

Intrepid 6.2 makes Continental Scale Geophysics and Feature Extraction more accurate, straightforward, and routine.

It includes our work for Intrepid3D which provides a variety of rendering changes that utilise 3D graphics and shaders, enabling larger datasets to be visualised. It also includes updates to the Geology from Geophysics tools so that they now deliver 3D datapoints with attributed properties such as susceptibility for feature extraction.


This automated feature extraction reduces uncertainty that is introduced by individual-interpretations.


Intrepid 6.2 introduces new features and tools, like the TrendQ Gridding, a new WormE GUI, and the refactoring of tools like terrain correction to make them more apparent and accessible than before.


Intrepid3D - Geology from Geophysics

Intrepid3D combines the work made for Intrepid 6.1.5 and preparations for GeoModeller.


Intrepid3D includes changes to all “geology from geophysics” tools so that each can now deliver 3D datapoints with attributed properties for feature extraction, a process and datatype that lends itself to our upcoming product GeoModeller.


3D Explore now includes custom shader code which optimises the mixing of geophysics signals without a loss of resolution. It also assists in the handling of large datasets.


Two new tools, TrendQ Gridding and Dataset Rarification are new additions in the Intrepid software package, with TrendQ also being available as a service provided by our team of consultants.


Intrepid 6.2 includes updates for 3D Explore, Isostatic Gravity Correction, the Multi-Scale Edge Detection Wizard, Intelligent Search (Batch) and the Gravity Import Wizard.


Version 6.1.5 carried numerous changes to the user interface, performance improvements and stability upgrades.

Continental Scale Geophysics

Our experience with Continental Geophysics has grown with time, as Australians we are well positioned to deal with continental geophysics.


Continental Geophysics follows from the processing of many datasets, resulting in “supergrids” like the Australian Magnetic Anomaly Grid. Typically these “supergrids” are composed of 800 to 3000 grids and can provide insight into deeper- tectonics and crustal architecture. The Continental Scale also requires novel enhancements and corrections like the Variable Reduction to Pole (VRTP), our newly updated Isostatic Correction and the AWAGS (Australia Wide Airborne Geophysics Survey). Each of these methods adjust for longer wavelength features.


Regular updates and recreation of these supergrids are strengthened and supported by Intrepid’s repeatable and automated workflows.


For current and prospective Intrepid users, see our updated Continental Geophysics cookbook for exposure to these practices.

TrendQ Gridding

The new trend gridding tool has been included as a software feature and as a service option for customers as part of our geophysical data processing. Trend gridding is a powerful tool for uncovering trends in your data that might otherwise be hidden due to the flight line direction. The TrendQ Gridded Product demonstrates the enhancements in quality and interpretability of the trended grid. This applies when there are 2D bodies causing the gridded signal to show Boundinage style manifestations, when the underlying geology is more uniform in thickness. These features, which are visible as circular anomalies in standard gridding process,can easily mislead interpretations but can be avoided by using the TrendQ process.

Intrepid Automation

Generated documentation and diagrams for the Google Protobuff API for Intrepid are now part of the software package.


These diagrams expose the structure and parameters used to automate processing and interpretation workflows. They are found in the Help Menu of the Project Manager, under Protobuf Documentation.

Superquadric Glyphs in 3D Explore - Providing Intuitive Visualisation of Vector, Tensor and Time Domain Measurement Data

As geophysical observations become more complex, involving phenomena like gradients and time decay curves, we can begin to see that our limited and standard imaging options available do not convey the complexity. Intrepid has begun using glyphs and the advances made in the modern graphics card to address these issues and provide intuitive visualisation of complex systems.


The latest addition to this effort is the superquadric tensor glyphs, as described by Kindlmann the superquadric provides a balance between the symmetry of ellipsoids, and shape and direction of cylinders and cuboids for the visualisation of tensor data.

Intrepid, AEM and AWS

Intrepid Geophysics has recently collaborated with Amazon Web Services to bring our AEM Inversion service to the cloud. 2.5D Airborne Electromagnetic inversions are now able to be run on AWS, allowing for rapid scaling in projects and faster turnaround for larger scale surveys. To learn more about Intrepid Geophysics collaboration with AWS and, see their interview with Des Fitzgerald on YouTube

Services and Expertise

Throughout the year Intrepid Geophysics has been routinely producing regional and permit scale results for global clients. Alongside our current services, the Intrepid Geophysics team have been adding further AEM products:

As well as Geological and Geophysical Products:

Incoming changes for 6.1.5

The traditional web-based technology used in JetStream is now upgraded, using the Google microservices and messaging, and the JetStream Service’s functionality has been extended in the Intrepid Project Manager. The JetStream catalog is also made more flexible, by being upgraded to the internal ioDB standard. Hence many more fields are “standard”, as are the set of tools to build and support the catalog.


Multi-scale edge detection wizard has been updated to enable all batch functionality including the loading and saving of task files.


GridMerge now supports 64bit indexing, which enables the tool to track the grid-refinements and processing for 32+ gigabyte output grids.
