Licenses can be obtained for commercial applications, for academic research, and for education (learning about inversion). Each of these three licencing arrangements is different. Please read the relevant sections below for details.


Commercial Licensing

UBC-GIF DOES NOT MANAGE COMMERCIAL LICENSING DIRECTLY. Software licenses for selected UBC-GIF inversion and forward modelling codes with which to carry out contract or other commercial work can be obtained from third parties. Please see the information below (New releases) if you are interested in acquiring the latest release of any code with the newest feature and most up-to-date documentation. 


New releases

All commercial licenses for the newest release (e.g. v5.0) of any UBC-GIF inversion and forward modelling code can now be obtained through Mira Geoscience, Ltd. The best way to contact them is via email at Their contact information is:

Academic Licensing

Program libraries for modelling and inversion that can be obtained for research use within an accredited academic institution include DCIP2D, DCIP3D, MAG3D, GRAV3D, EM1DFM, EM1DTM. These programs will be fully function only on the computer specified on the application form. In return for providing access to software, we request details about how the code was applied, and a case history if possible.

Note that "academic licenses" are not the same as "educational licenses" (see below).

Steps for acquiring an academic license

NOTE: We ask research supervisors or principle investigators to apply, even if codes are to be used by graduate students. The steps to obtain an academic license are the following:

  1. Obtain Educational versions of the program library you require. Contact UBC-GIF by email for details. If you have not already done so, learn about the codes: There are many tutorials & manuals on this website - see the "Software" and "Resources" menus, and practice using the codes by forward modelling and inverting the test data supplied. This helps determine if codes are suitable for your research.
  2. Print and read the license agreement. You must agree to all terms.
  3. The Principle Investigator or Research Supervisor can complete the application form (please NOT a student).
  • NOTE: You must decide which actual computer will run the codes, than find that computer's Physical Address. Instructions are on the application form. When you change computers, a new key-file can be obtained by re-applying. 
  • Clicking the submit button on the application form implies you have read, and agree to, the complete license agreement. 
  • If there are difficulties or questions or special circumstances, please contact us by email.

 4.  Upon approval, a key-file will be sent via email to the licensee designated on the license form. Follow instructions that come with that key-file. This will activate full functionality on the computer defined in your application form. 

 5.  All academic licenses will be time-limited to one year. You can re-apply after that time. This ensures that everyone is using the most recent versions of codes, so you don't have worry about upgrading. Besides, most people upgrade their computers quite often, and when this is done you will have to reapply with a new physical address anyway.

 6.  Read the Important Notes below

  1. No academic license is to be distributed in whole or in part within, or outside, any organization. Nor is software licensed for academic use to be used for commercial purposes within an organization, or for consulting purposes. Additional licenses may be obtained if other members of an organization need the software for research.
  2. Our policy with respect to inversion codes has been to make them available, at no cost, to universities for scientific research purposes. In return we have asked for information on how the codes have been used, and for case histories and papers that have been generated by using the codes. We also asked that proper acknowledgement be provided (point 5 below).
  3. Unfortunately this policy has not worked well and we have received feedback from very few users. Despite this, we will continue to provide the codes. We ask however, that recipients pay much more attention to our requests for feedback.
  4. Those who are new to UBC-GIF modelling or inversion codes are strongly advised to obtain the instructional CD-ROM called Inversion for Applied Geophysics (IAG). It costs less than a text book and contains background information, tutorials, recommendations regarding workflow, examples, and all documentation. IAG also contains the restricted, educational versions of some UBC-GIF programs so you can practice obtaining useful results before committing to a fully functional program.
  5. Utility codes (plotting, user interface, etc.) are freely available. A separate page provides details, manuals and download instructions.
  6. When referencing the use of DCIP2D, DCIP3D, MAG3D, GRAV3D, EM1DTM or EM1DFM in your publications, please use the citation shown at the bottom of our "Main programs" page.

Educational Versions

Educational versions of DCIP2D, MAG3D and GRAV3D are freely available. These versions of the codes are fully functional except that the number of data points, and the size (number of cells) of models are both restricted. The reason for this is to allow unrestricted access to modern inversion codes for learners (students and professionals), but to prevent free access to the codes for commercial use. Education versions of all three codes are on the IAG CD-ROM. Please see the IAG page for details.
