Don't just process your orientation data, explore it!
See your data four different ways at one time while
you edit, search and analyze them.
For structural geology, geological engineering,
sedimentology, glaciology, palaeomagnetism, physical geography and any
other scientific discipline where orientation of features is important.
SpheriStat 3.1 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 79
Map Symbols and 18
Net Symbols (or 36 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.
And now, you can customize both symbol sets and even add your own
favorite symbols, using our new Symbol
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
Select the records directly with the mouse in any of the diagrams, or
by using the powerful Boolean selection procedure! The selected points
are highlighted in all displays, so you can see spatial and orientation
relations at the same time.
And a simple mouse click lets you make a new data set from the
sampled points for detailed statistical analysis.
Lots of Ways to Analyze Your Data
Choose from a wide variety of techniques. SpheriStat offers more
statistical results than are offered by any other single orientation
analysis software. And if you can't find what you want, you can add your
own methods . . . SpheriStat is extendible!
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
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.
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
- Calculate Intersection Lineations, Lineations from
Rake, Planes from Lineations, Apparent Dips,
Lineaments from End-Point Data,
Small Circle Intersections -- 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 Girdle through your
Customize Your Plots and Data Tables
SpheriStat gives you control over what features to show in your plots
and data tables.
SpheriStat can print up to 17 different diagrams and statistical
results using your Windows-installed printer.
We provide a new print preview option so you can see how the page
will look. And the preview viewer is even easier to use.
You can copy your diagrams from the main windows and from many
analysis dialogs to the Windows clipboard.
You can also 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, when viewed colored glasses.
- 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 278-page manual and on-line help explaining all the
techniques, with references.
Features New to Version 3:
- Data set size is limited only by available computer memory.
- Support for long file names.
- More plotting options:
- User-created map and net symbols
(with optional Symbol Editor).
- Option to change the default map and net symbol sets.
- Individually sized net symbols.
- Colored map and circular diagram symbols.
- Display of planar data as pole trend and plunge.
- Added output options for analyses.
- Publishing of datasets with custom symbols included.

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

wrote: "Your software is fantastic!"
David Rhys of Panterra Geoservices
Inc., Surrey, BC wrote: "Thanks again for continuing to
maintain this valuable software. It surpasses the flexibility
and utility of any other structural data analysis software I
have encountered. ... I have sent several of my clients in your
direction over the last few years and all who have purchased
your software are happy with it."
Graham Spray, M.Sc., University of New
Brunswick, wrote: "I love SpheriStat. I think it’s a
terrific little program. I’ve used it to write my M.Sc. thesis
and prepare several exploration reports. I think the
structural symbol mapping function is fantastic, and the
gridding/contouring options are excellent. SpheriStat has helped
me to unravel some seriously structurally complex terrains!"
