What's New at the UBC-GIF ...
From the director of UBC-GIFOur policy with respect to inversion codes has been to make them available, at no cost, to universities for teaching and research purposes. In return we have asked for information regarding 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. Unfortunately this policy has not worked well and in six years we have only received information about three projects even though more than 300 licenses have been issued. Despite this, we will continue to provide the codes. We ask however, that recipients pay much more attention to our requests for feedback. In addition, new inversion codes that are being developed, and enhanced versions of older codes, will be released on a more restricted basis.
Finally, when referring to the use of these programs in your publications, please use a citation as shown on our FAQ page. Doug Oldenburg Director of UBC-Geophysical Inversion Facility |
Here we will list the most recent additions to our web site, and inform you of publications, events and activities that members of the UBC-GIF are involved in.

June 2008
We have updated the GIF publications page, as well as the UXO subgroup publications page. We also have two new employment opportunities:
July 2007
The IAG (Inversion for Applied Geophysics) learning resource package is now avaliable ! UBC-GIF has released it as a free download from flintbox
, a global intellectual property exchange. See the IAG outline page for details.

News Flash: Congratulations to PETER LELIEVRE (Ph.D. Candidate - Supervisor: Dr. Doug Oldenburg) Peter Lelievre received the award for best student presentation at the SEG meeting in New Orleans. SEG's Best Student Paper Presented at the 2006 Annual SEG Meeting "3D magnetic inversion for total magnetization in areas with complicated remanence", P. Lelievre, D. Oldenburg, N. Phillips. Congratulations Peter!
May 2007
The case histories list has been augmented with pointers to published articles. There are now 21 case histories liste.
March 2007
Updates to many graphical user interface (GUI) codes:
- MeshTools3D
- Filenames for all GUIs now accept spaces.
- Speed up SLICING using Shift-Click. Also, there are improvements to the way animations are generated, and the way data sets are loaded and displayed over models. See the updated manual and the meshtoools history file identified at the top of that manual.
- gm-data-viewer
- Filenames for all GUIs now accept spaces.
- dcip2d
- Wenner and RealSection data can be accomodated in the GUI and data viewer (since December 2005).
- Filenames for all GUIs now accept spaces.
- mag3d
- grav3d
Go to the utilities list to see dates of most recent versions, and to dowload GUI codes. See program manuals (Software manuals in the website's main menu) for changes, especially the GUIs, MeshTools3D and gm-dataviewer.
February 5, 2007
An interactive workflow document explaining how to carry out 3D inversion of magnetic or gravity data has been prepared. There are a few details still to be completed, but it is substantially complete. Find it via the tutorials page.

Congratulations to Doug Oldenburg on a Special Tribute by Association for Mineral Exploration BC:
"Dr. Doug Oldenburg, Professor in the Department of Earth and Ocean Sciences and Senior Keevil Chair in Mineral Exploration at the University of British Columbia, is recognized for his contributions to significant advances in mineral exploration through the development of innovative new approaches to the modeling and interpretation of geophysical data at the Geophysical Inversion Facility at UBC," said Pease. The award recipients will be honoured by their peers at AME BC's Annual Awards Dinner on Wednesday, January 31, 2007, at The Westin Bayshore, Vancouver during Mineral Exploration Roundup 2007. "

Software documentation now includes pointers to complete manuals in PDF format. These are simply combined from the web page chapters, but they may be useful for those wishing to print a paper copy of the manuals. See the Software Manuals menu.
September 5, 2006
- The UBC-GIF website has an upgraded menu system. Content is substantially the same as before, but organization of some sections has been changed. Please modify your bookmarks accordingly.
If you find problems please contact ubcgif@eos.ubc.ca and include the page address that you are referring to. Thanks for helping ensure the information is correct and accessible.
- There are a few more papers on the publications page, and the software manuals are now in a more web-friendly (and more easily maintained) format. Also the Workflow for DCIP2D has been upgraded, although more changes to that are on the way soon.
- Some new pages are now included, such as a (growing) glossary of inversion terms.
August 21, 2006
Material presented by Nick Williams on research related to the MDRU-UBCGIF joint project are now available via the publications page (items 98 and 99). Items are:
- Estimating sulphide abundances from 3D physical property models (poster with MDRU coauthor Greg Dipple).
- Applying UBC-GIF potential field inversions in greenfields or brownfields exploration (Powerpoint (PDF) and extended abstract paper)
July 25, 2006
The UXO group's web information has been reconfigured to conform with UBC-GIF website standards. Also this research group now figures prominently on the main UBC-GIF website left-hand menu.
July 1, 2006
The FAQ page has been updated. Not much new, but all the old links that did not work have been fixed.
Two little utilities have been added/upgraded - mod2xyz and model2xyzval. These are command line utilities for converting model/mesh file pairs into a single column-based file that can be read by other programs.

MAJOR CHANGE TO ACADEMIC LICENSING. SEE SOFTWARE=>LICENSING.
- Latest versions of DCIP2D, DCIP3D, MAG3D, GRAV3D, and EM1DFM are now available for academic licensing.
- The application process is now based on a web-form.
- Academic licenses will be tied to an individual computer. See the application process.
- 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.
Educational versions of GRAV3D, MAG3D and DCIP2D are available. Until the IAG CD-ROM is completed (watch this space ...), educational versions of these three codes can be requested via email to the UBC-GIF.
There are NO EDUCATIONAL VERSIONS of dcip3d or em1dfm, but these are available for academic licensing.
June 9 2006
MeshTools3D continues to be upgraded. New features include the ability to plot more than one data set in several different ways; new colour bars; more error checking, more versatile parameter saving, and others. See MeshTools3D documentation and the utilities download page.
GM-data-viewer has also been upgraded. It is now useful for a range of data sets. There are also options for changing the colour scale, plotting elevation from your data file's 3rd column, and for cropping or downsampling your data set. See gm-data-viewer documentation and the utilities download page.
