Rod Holcombe software distribution site

This site contains downloadable software and GIS tools developed by Rod Holcombe. Most are free to download and use, although the Windows application GeoCalculator requires a paid licence for continued commercial or site use.  The software includes packages for plotting stereographic projections, rose diagrams and wind roses (GEOrient); for structural and oriented drillcore calculations (GeoCalculator); for strain and shear zone calculations (StrainCalculator  & GeoFryPlots); microstructural behaviour (GhoshFlow) and GIS tools in MapInfo and QGIS for plotting structural symbols on maps (GeoMapSymbol  & GeoQSymbol), and Mapinfo tools for calculating vector trends (azimuths) and lengths (GeoMapVector), and extracting nodes from polylines (PolyNodeExtractor).

Notes:

  1. The software is specific to Microsoft Windows. (It may install and run under Windows emulations on Macs, although Help links within each application will not work).
  2. *The packages can be used freely by academics (teachers and students) for teaching and non-commercial research purposes, but please acknowledge the author in any publication or figure arising from the use of these packages.
  3. For commercial users the unregistered download version of GeoCalculator can be used for evaluation purposes only for a reasonable interval that must not exceed two months The software must be registered for continued commercial use. Academic users who wish to access the full File I/O capabilities and drillhole calculations must also purchase registration.
  4. Although every effort is made to rectify bugs as they are recognized, the author cannot guarantee that these packages are without error, and assumes no responsibility for their use, or for interpretations based on their use.
  5. Travel commitments may occasionally delay my ability to handle email queries promptly
