WebDec 14, 2024 · Stereographic projections are geometrical mapping functions to project a sphere that contains directional features of interest onto a plane. This type of mapping is either conformal in that it preserves the angles at which different curves meet or it is area-preserving in that two sectors with the same area on the sphere have the same areas … WebDec 17, 2024 · The results are shown in lower-hemisphere stereographic projections (Figures 8,9). Discussion. The results obtained from DSM methods and scanline differ by about 10° for both investigated outcrops (Figures 6,7), because DSM methods measure only apparent and not true strike. Each point at the edge of various lineaments from DSM …
