Product Description
Topographic elevation is the vertical distance above the reference ? geoid, a precise mathematical model of the ? Earth's ? sea level as an ? equipotential gravitational ? surface. ? Topographic prominence is the elevation difference between the ? summit and the highest or key col to a higher summit. Topographic isolation is the minimum ? great circle distance to a point of higher elevation. This article defines a major mountain peak as a ? summit with at least 500 meters (1640 feet) of topographic prominence. An ? ultra prominent peak is a summit with at least 1500 meters (4921 feet) of topographic prominence.
