Maximum Elevation Figure or MEF is the highest feature within an area. It is of interest to airplane pilots so they can fly above mountain peaks without the worry of flying into them. Features include terrain, trees, towers, and the like.

In the USA, the Federal Aviation Administration issues Sectional Charts. Each 1 degree of longitude and 1 degree of latitudes are divided into 4 pieces called quadrangles, each 1/2 of degree on longitude and latitude. Each quadrangle has its MEF printed in it in thousands and hundreds of feet above mean sea level. For example, 10⁵, means that the highest elevation is 10,500 feet within that quadrangle.
