A vertical distance relative to a reference point. The reference point can be
EXAMPLES:
Example 1: The elevation of the Eiffel tower is 980 feet. This means that the distance between the ground and the top of the tower is 980 feet. (Note: the bottom of the Eiffel tower is 95 feet above sea level, to the top of the Eiffel tower is 980 + 95 = 1075 feet above sea level)
Example 2: The village is at an elevation of 1800 feet. This means that the village is 1800 feet above sea level.
Example 3: The house is at an elevation of 7 feet from the street (assumed point).
