The centerline is the axis around which the turbine rotor spins.
To measure an angle of elevation using a protractor, first position the protractor so that its center point aligns with the vertex of the angle you are measuring. Ensure the baseline of the protractor is level with the horizontal line from the vertex. Look up towards the point creating the angle of elevation and read the measurement on the protractor where the line of sight intersects the degree scale. This reading indicates the angle of elevation from the horizontal to the line of sight.
No. Every point on a contour line has the same elevation.

Contour interval
A contour line is a line defining elevation on a map.
No. Contour lines connect points of the same elevation
The elevation of the highest contour line on hill W is the value indicated on that specific contour line, representing the peak of the hill. On a topographic map, contour lines are used to show the elevation and shape of the land, with each line representing a specific elevation.
topographic elevation
To determine elevation using a topographic map, look for contour lines that connect points of equal elevation. Find the contour line closest to your location and determine the elevation value listed on that line. Elevation can be calculated by adding or subtracting the contour interval value from the listed elevation.
The angle of elevation is looking at an object above your line of sight.
