For the fault line, according to data collected by DEM major shift position did not constitute treatment and to determine a network region. When the P value is positive when in the AB on the left, when the value is negative on the right, when in the same line is 0.5 Conclusion We introduce the contour-based method of generating DEM and contour lines described in detail discrete points,[link widoczny dla zalogowanych], the characteristics of Delaunay triangulation, TIN, and the establishment of a problem solution to a wide range of products for today's application of DEM a shallow exploration and practice.
