Elevation (The height of a fixed position above sea level) Example: Denver, Colorado in the United States is 5,183 ft. above sea level. 1  Find The Elevation Of Most Any U.S City.  Find the high and low points in any country.
Now, to calculate the elevation of the middle point, the height of the instrument (HI) is subtracted from the foresight reading of Rod 2. Elevation of middle point = 105 ft â 6 ft = 99 ft. The next step in extending the level line is to move the level to a new location between Rod 2 and the new point or benchmark.
