- On the contour map in Figure A6, the contour interval is 20 m. The horizontal distance AB = BC = 200 m. Report the elevations (metres above mean sea level) of points A, B and C and calculate the average ground gradient between A and B, and between B and C. Legend sea contour It hachure marks stream Figure A6 We have three points, S1, S2 and P, of known coordinates (Eastings and Northings). Name the setting out parameters we need to know in order to find the location of P on the ground using S1 and S2. Assume that the total station is set up on S1 and line S1 S2 is your reference bearing. Make a sketch to support your answer (required).
