GeoCalculator

GeoCalculator is a Windows software application whose purpose is to help you perform calculations and conversions for geological data.

It supports many calculations, such as lines of intersection, angles between lines and planes, apparent dips, rotations, as well as oriented and partially oriented drill hole calculations. Format conversions include dip/dip dir'n to strike/dip, azimuth to quadrant notation, and pitches/rakes/hades to plunges.

The GUI may seem a bit overwhelming at a first glance because the program integrates all supported calculations in a single panel. However, they are well organized so you can quickly get an idea where to get started. In your rescue comes the help manual which provides extra details about the program’s features.

You are allowed to manually type in the line or plane orientation directly in the primary panel, or import batch data from ASCII text files or clipboard content. A dedicated window reveals the results.

GeoCalculator gives you the possibility to perform all sorts of calculations, which are related to angle between two lines or planes, angle between line and plane, line of intersection between two planes, plane bisecting two lines, and rotation of a line or plane around an axis.

What’s more, the application helps you convert line pitch in a plane to plunge and line plunges to pitch in a plane. Conversions can also be carried out between orientation conventions of a given plane or line.

You are offered the chance to work with different types of drill core orientations (oriented, partially or un-oriented), perform batch processing of drill hole data, save the results in ASCII format to output files, and check out the results in a stereographic projection window which can be copied to GEOrient plots.

GeoCalculator comes packed with several handy features for helping you calculate various parameters for structural oriented planes, and is suitable especially for advanced users. In case you want to skip the installation steps, you can have a look at the portable version of the utility, GeoCalculator Portable.

Note: The application is free to use for academic and non-commercial purposes but the batch processing function is limited to five entries. For other uses you need to purchase a license.
