Determine the difference in elevation between B and C
3. In the figure below, a vertical angle of -14°30' is read to a target 1.75 m above point M. The measured inclined distance (S) is 644.15 m and the elevation of point K is 320.70 m above mean sea level. If the height of instrument at K is 1.27 m, the elevation of M, considering effects of the earth's curvature and atmospheric refraction, is? HORIZONTAL LINE HI = 1.27 m S= 644.15 m M RR = 1.75 m DATUM (MEAN SEA LEVEL) Elev K = 320.70 m DE -14°30
A direction measured clockwise from a given zero is called: A bearing An azimuth OAmagnetic declination A local attraction
situation 1] From an instrument set up at point A, the angle of elevation of point B is +16 81' while point C is +7°41'. Furthermore, it was found out that the difference in elevation between points B and C considđering the effect of earth's curvature and refraction is 11..983 m. Point A is in between B and C. If c is 1951 meters from A. how far is B from A? If the elevation of point A is 1905.342 m above mean sea level, what is the elevation of B? : What is the elevation of C? ii. iii.
