GeoCalculator© v4.x

is based on the familiar Windows Calculator but takes geological structural data for input and output. Calculations include most common structural geometrical calculations as well as drillhole calculations for oriented, partially oriented, and unoriented core.

Notes:

The software is specific to Microsoft Windows. (Users have reported that it does not install under Windows emulations on Macs)

GeoCalculator opens initially in its unregistered form, displaying an unregistered notice and inviting registration. The unregistered program contains all the features of full registration except that the number of data that can be batch processed by file Input/Output is strongly restricted. Registration (paid) removes this restriction.

*ACADEMIC USE: GeoCalculator packages can be used freely as an unregistered version by academics (teachers and students) for teaching and non-commercial research purposes. Academic users who wish to use the registered version, which removes the file Input/Output restrictions, must also purchase registration.
For commercial users the unregistered download version can be used for evaluation purposes only, and must be registered for continued commercial use.

Although every effort is made to rectify bugs as they are recognised, the author cannot guarantee that these packages are without error, and assumes no responsibility for their use, or for interpretations based on their use.
Frequent field work commitments may occasionally delay my ability to handle email queries promptly

Note:
See the bugfix text file or the What's New section in the GeoCalculator Help file for details on progressive changes to the program

Note: Version 4.9.6 contains an important debug of the 'Oriented Core routines'. (That is, where a known reference plane is used to determine the orientation of an unknown plane in core that has not been oriented). All users who use such drillhole calculations should upgrade with the version shown here.

This file must reside in the same directory as the .exe file. If the Help file contents can not be viewed then follow the procedure for unblocking the file as outlined at right.

As part of Microsoft's security measures you now have to Unblock any .chm file in order view it. This site explains the procedure...
