Name of Lecturer(s)
Prof.Dr. Sebahattın Bektas
Learning Outcomes
  1. make spherical triangles solutions with different methods and compare them.
  2. To be able to know geodetic curve definition, importance and normal section observations should be reduced to geodetic curve
  3. comprehend the reason of the ellipsoid geometry
  4. ellipsoid geometry
  5. understand the necessity of calculation on sphere instead of ellipsoid and selection of these spheres.
