Correction of Line

The Terzaghi method is widely used to correct the line-sampling bias of rock discontinuity orientations The method includes four procedures, one of which is meshing the stereographic projection diagram into cells The method is based on the bias-compensatory factor, 1/sin θ, where θ is the angle between the scanline and the discontinuity defined at each cell center...
