• GEOrient plots orientation diagrams (equal area, or equal angle stereographic projections, and rose diagrams) as shown in the composite image above (or this screenshot). Data is entered either by pasting from the clipboard from other applications, or from ASCII text files, in a wide range of file formats, and using a range of orientation conventions. The prime purpose is for the plotting of geological structural data but the plots may be applied to a variety of spatial/orientation data, including wind data.
• Data can be copied and pasted, for example, from external spreadsheets and databases. Using this system orientation data from tables displayed in a map in a GIS map databases (such as MapInfo) can be copied and pasted easily into GEOrient.
• Data can be presented either as coloured symbols representing point densities, as great circles, as beta intersections, as contours of gridded point density, or as rose diagrams of polar or non-polar data. The primary plot data can include appended numeric or non-numeric information (such as length, weighting factors, mean wind data, drillhole depth ranges, etc) to allow either classification of the data within the plots, or for various rose diagram options (e.g. Length-Azimuth plots, Wind Energy plots, Mean Length/sector and Variance/sector plots). Various corrections can be applied to frequency rose diagrams for linear data sampling bias (Terzaggi corrections).
• Linked fault plane and slip data can be plotted as either slip arrow plots or as kinematic axes plots.
• Data from multiple files can be merged as a single dataset, or can be overlayed as separate plots using different symbols. Multiple plot windows can be opened simultaneously and can be arranged on a page prior to printing.
• Best-fit great circles, beta axes,  and vector mean and variance statistics are automatically calculated. Other girdles and small circles can be manually fitted to the data using the mouse to drag girdles into position. Data can be easily added with the mouse, or can be edited within, and between, plots using normal Cut/Copy/Paste mouse actions.
• Annotated points using any symbol or colour can be overlain on the basic plot.
• Data can be rotated in various ways, and linked data (such as sedimentary flow directions on bedding planes) can be rotated to the horizontal by rotating the associated bedding planes and fold hinges.
• Plots can be linked to MapInfo mapper windows and data selected in one will be selected in the other.
• The limit on the number of data is system memory and resources. Registered users can display up to 99 simultaneous plots (but more than 20 becomes unwieldy). Unregistered users are restricted to 3 simultaneously open plots.
• Download the Help file or the compiled Help file for specific details.

Notes:

GEOrient 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 maximum number of plot windows that can be opened simultaneously is restricted to 3, and the opening registration notice will continue to be displayed on startup. Registration (paid) removes both these restrictions and initially sets the default maximum number of plots at 10. (This number can be then be changed from within the Preferences dialog accessed from the View… menu).

*ACADEMIC USE: GEOrient packages can be used freely as an unregistered version by academics (teachers and students) for teaching and non-commercial research purposes, but please acknowledge the author in any publication or figure arising from its use. However, academic users who wish to use the registered version, which removes the plot window 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
