WebWhat is the curvature and refraction effect on surveying? Curvature and refraction effects should be accounted for in precise levelling work and also if the sights are too long. The effect of curvature is to cause the objects sighted, to appear lower then they really are. WebCurvature and Refraction. Page 3 of 3. 3. Curvature and Refraction. a. What. The fundamental difference between plane and geodetic surveying is the latter takes into account the size and shape of the earth. However, there is no distinct point where surveying crosses from one classification to the other; there tends to be a gray area in between.
