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 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, 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 data.
