How to compute the elevation of the target station/ Civil Engineering
The EDM (ELECTRONIC DISTANCE MEASUREMENT) SLOPE DISTANCEBETWEEN TWO POINTS IS 5,170.11 FT. AND THE VERTICAL ANGLE IS+2DEGREE’45’30”. THE VERTICAL ANGLES WERE READ AT BOTH ENDS OF THELINE AND THEN AVERAGED USING A CO-AXIAL THEODOLITE/EDM COMBINATION.IF THE ELEVATION OF THE INSTRUMENT STATION IS 630.15 FT AND THEHEIGHTS OF THE THEODOLITE/EDM AND THE TARGET/REFLECTOR ARE ALLEQUAL TO 5.26 FT. COMPUTE THE ELEVATION OF THE TARGET STATION ANDTHE HORIZONTAL DISTANCE TO THAT STATION.
