網頁A stereonet is a tool used by geologists to analyze and interpret orientation data, such as planes and lines. The stereonet is a representation of the lower half of a sphere; however, because the stereonet is in 2D and a sphere is 3D all the 3D data needs to be projected into the 2D plane.

Surfaces, or a pole perpendicular to the surface, are oriented by their intersection with the surface of a bowl. The stereonet grid is used as a protractor, and in structural geology, it is used to plot attitudes of planes and lines. Uploaded on Nov 21, 2014. 網頁Stereographic is an azimuthal projection. In the polar aspect, the meridians project as straight lines originating at the pole and all angles between them are true. The parallels are shown as concentric circular arcs. Their spacing rapidly increases from the pole. All graticule line intersections are 90°.
