Distribution policy

UBC-GIF graphical user interface (GUI) and utility programs are freely available. These are NOT the inversion or modelling programs - they are provided to assist with running the forward modelling and inversion codes, and with inspecting data and models. Industry standard outputs can not be produced, nor are the codes designed for managing geophysical data sets or for doing other forms of data processing.

  • All programs are copyright protected as indicted in the  Help menu, About option of each program. They are freely available, BUT CODES MUST NOT BE RE-DISTRIBUTED.
  • These programs are not guaranteed in any way.
  • We can not provide support for their use.
  • Source code is NOT available.
  • Utilities and documentation will be upgraded periodically without announcement so please check back occasionally for newer versions.
  • Please see the software page for information on licensing of inversion and forward modelling codes.

Utilities installation notes

  • Graphical utilities are written for the Windows XP operating system.
  • Utility programs are provided in zipped archives via links in the table below.
  • Each utility code is a single executable program for the Windows operating system.
  • To install, simply extract the executable programs from the archive and place them in a suitable subdirectory of your hard drive.
  • All UBC-GIF programs that are expected to work together (forward modelling, inversion, and graphical utilities) must reside within the same sub-directory.
  • Note that only UBC-GIF input and output file formats are supported; see relevant documentation.

Other notes

  • The version of licensed code (or the build date of utilities) can be found in the program's Help menu, About option.
  • Utility codes may be updated. Only the most recent versions will be available.
  • No provisions are included for "industry standard" hard copy output. However, all images can be saved as bitmaps to the Windows clip-board for pasting into documents.
  • We are interested in your comments (good or bad) with respect to the forward modelling, inversion or utility codes. Not all suggestions provided by users can be implemented, but we will consider suggestions as codes get upgraded. You can pass these along via email to ubcgif@eos.ubc.ca.
  • For frequently asked questions, and good advice, see the FAQ page.

Linear inversion applet  
May05 The linear inversion JAVA applet used in tutorials and workshops.

MeshTools3D

 Mar07 For viewing 3D models that are represented by a rectangular mesh in the UBC-GIF format, with optional topography. Functions include mesh construction, display via slices (in either dimension or diagonally) and isosurfaces (positive or negative), overlay of surface data as a transparent colour contour map, rotation, animation of views, block model construction, and (if forward codes are licensed) calling of forward 3D magnetics or 3D gravity codes.   HTML 
gm-data-viewer Mar07 View potential fields data (gravity or magnetics) as colour contour plots and create a line profile display in any direction from the map. Also adds noise or assigns errors to data. HTML
mag3d-gui Feb07 NO inversion or modelling codes: This is a graphical user interface only. It is not useful unless there is a valid licensed copy of the MAG3D program library. HTML
User interface only. NO inversion code.
grav3d-gui Feb07 NO inversion or modelling codes: This is a graphical user interface only. It is not useful unless there is a valid licensed copy of the GRAV3D program library. see mag3d-gui
User interface only. NO inversion code.
dcip2d-gui Feb07 NO inversion or modelling codes: This is a graphical user interface only. It is not useful unless there is a valid licensed copy of the DCIP2D program library. HTML
programs

Four dcip2d utilities in one archive.
dcip2d-data-viewer Mar07 View 2D DC resistivity or IP pseudosections with topography (pole-pole, pole-dipole, dipole-dipole, wenner, realsection). Also adds noise or assigns errors to data. HTML
dcip2d-model-viewer Feb07 View 2D models and meshes used by 2D inversion and forward modelling code, including depth of investigation. Also view inversion convergence curves. HTML
dcip2d-model-maker Feb07 Graphical user interface for constructing blocky 2D models, digitizing to a 2D mesh, and running DCIPF2D forward modelling code (if DCIP2D is licensed). HTML
dcip2d:
mod2xyz 		May06 A command line utility for converting 2D model and mesh files into a single XYZ file with model cell values located at the centres of cell locations. Useful if 2D models need to be plotted using third party programs, or if you want to extract a portion of the model. Text
3D:
model2xyzval 		May06 A command line utility for converting 3D model and mesh files into a single XYZVal file with model cell values located at the centres of cell locations. Useful if 3D models need to be plotted using third party programs, or if you want to extract a portion of the model. Text
3D:
remesh3d		 May07 This command line utility interpolates a model on one mesh onto a second mesh. Useful for comparing models of different properties obtained by inversion of different data sets over the same target. Text
