SpheriStat 2.2 for Windows is an integrated, powerful and easy-to-use analytical tool for making stereonets, structural maps and rose diagrams, with lots of display, printout and export options.

Easy Data Entry and Display

Enter your data manually using the handy, customizable spreadsheet-like editor or import them as ASCII files from your database. SpheriStat can import a variety of ASCII file structures, measurement conventions and field delimiters. Assign symbols for the map and stereonet plots. Choose from 77 standard Map Symbols and 16 Net Symbols (or 32 net symbols if you are plotting axial data only). Use as many different symbols on a diagram as you want. SpheriStat has two pop-up windows that show you all the map and net symbols, with their codes, that you can use in your diagrams; the windows stay on top, so they are always available when you need them. On the stereonet, you can plot points (lineations or poles to planes), great circles (planes) and small circles (cones). You can even add additional great circles, small circles or points as markers, without affecting the calculations. You can choose the individual color of each net symbol; add your own titles and other labels, using your choice of text and frame colors; load a contour plot or histogram produced from a different data set and include a contour level scale beside the net.

Flexible Data Sampling

Lots of Ways to Analyze Your Data

• Measurement of Angles and Distances directly on the net, map and rose diagram! Just click and drag the mouse cursor. The reading appears in the status line above the drawing.
• Data Rotation to best show the patterns. In the rotation windows, drag any net or rose diagram point to a new location and SpheriStat does the rest. Or manually enter the orientation of the rotation axis and the rotation angle. And you can rotate as many times as you wish; SpheriStat keeps track of the last rotation and the total of all rotations. You can also rotate only part of the data, leaving the rest as is. And SpheriStat can even rotate and replot your map, so you can make down-plunge projections or view your data from different directions.
• Point-density distribution on the net (Gaussian, Kamb, Schmidt and Starkey methods) with filled/colored contours and full statistics -- look for significant clustering patterns in your data. You can save and reload the contour plots, too.
• Density-peak removal, with statistics -- find the statistical significance of that secondary peak.
• Spatial averaging on the map, with optional weighting methods, station statistics and more uniformity tests -- look for trends and patterns on your map.
• Principal direction analysis (eigenvector or Fisher statistics) -- find the best-fit point maximum or great-circle girdle in your data. And save these directions as special markers on the plots.
• Cluster analysis with statistics and an option to create a separate data set for each cluster -- separate groups of directions for individual analysis.
• Five uniformity tests for the orientation data -- determine whether that cluster or girdle is really significant.
• Circular histograms on the rose diagram (bar, peak or Gaussian-smoothed) with full statistics and various plotting options -- look for mean directions and significant peaks. You can save and reload the histograms, too.
• Calculate Intersection Lineations, Lineations from Rake, Planes from Lineations, Apparent Dips, Lineaments from End-Point Data -- use your field measurements to determine attitudes of planes and lines.
• Solve 3-Point Problems -- find the best-fitting plane through points on the surface or in inclined boreholes.
• Calculate the Terzaghi Bias Correction for borehole and outcrop fracture surveys.
• Calculate the attitude of planes in borehole drill cores from Craelius Alpha/Beta Measurements .
• Calculate the Best-fit Small Circle through your data.

Customize Your Plots and Data Tables

Output Options

SpheriStat can print up to 17 different diagrams and statistical results using your Windows-installed printer. We even provide a print preview option so you can see how the page will look. You can also copy your diagrams to the Windows clipboard or export your plots to a Windows metafile or a DXF file for input into other applications that accept these formats.

Other Useful Features:

• Stereoscopic 3D view of the net, using the colored glasses provided with the software.
• Choice of annotated or "stick-figure" map symbols.
• Option to scale the map symbols individually. Plot a lineament map using the symbol scaling feature
• Optional mid-session change of project code and custom settings.
• Automatic timed backup of all modified files.
• Includes a 250-page manual and on-line help explaining all the techniques, with references.

User Comments

Here‘s what our users are saying: "looks good!", "congratulations!", "one of the most powerful and complete programs for structural analysis", "let me know if you do a Mac version!", "great program!", "very useful program!".

Dr. Eugenio Castelli in Trento, Italy, wrote: "Your software is fantastic!"

Dr. David B. Seymour of Tasmania Development & Resources wrote: "Someone has finally written a truly professional-grade structural analysis program in Windows. One of the biggest steps forward in structural geology in 20 years! ... SpheriStat is already proving invaluable, particularly in structural domain analysis where domains can now be recognized in a fraction of the time. The program is also quick to learn, despite the level of sophistication. One interesting aspect is that the XYZ-linked data format allows the possibility of importing structural data sets which have previously been generated for map plotting in my organization's ArcInfo GIS system. ... Keep up the good work!"

Duncan Cogswell of Borehole Information Technology, Victoria Park, Australia, wrote: "I've found SpheriStat to be the best technical and presentation software of structural data. For my work, it is important to keep ahead of the competition by more technical analysis and better presentation, in terms of appearance, detail and colour. ... I know that a lot of people have been impressed with it in Australia and believe it is more versatile than Dips."

Dr. Mike Stubley of Stubley Geoscience, Nelson, BC, wrote: "Ideal for my needs, with meaningful and intuitive statistics. The manual is (surprisingly!) clear and easy to use, and includes sections on the theory and limitations of various analytical techniques. Well done!"

Dr. Mel Stauffer of the University of Saskatchewan wrote simply: "I like SpheriStat."

Dr. Louis R. Bernier of Géoberex Recherche, Ile Perrot, Quebec, wrote: "Great piece of software. Importing ASCII data files is straightfoward. I have been able to export data into Surfer 7 and Corel Draw 7 without any problem. The manual is very well written and can be understood even by non-structural geologists! The software is a breeze to use. My only regret: Not to have bought it sooner. Keep up the good work."

Dr. Margi Rusmore of Occidental College, Los Angeles, California, wrote: "I own and enjoy SpheriStat 2.2. This is the best stereonet program I've used. I love the interactive capabilities."
