Remote VOXI TDEM Modelling and Inversion CourseThis instructor-led remote course will teach you about Time Domain Electromagnetics, modelling and inversion using VOXI Earth Modelling service.

The course uses hands-on activities to demonstrate key considerations for data preparation, testing acquisition hypotheses with forward modelling, auxiliary parameters for inversion setup, best practices for constrained and unconstrained inversions. Participants will have the opportunity to create models during and after the workshop using VOXI TDEM Earth Modelling.

Registration includes complimentary access to everything you need for the course, including Oasis montaj, EM Utlities extension and subscription to VOXI Earth Modeling.


2 x 4hr sessions (run over 2 days = 8hr)
