This is a plugin for Antarctic Mapping Tools. Just two simple functions for converting between geoid and ellipsoid elevations. Geoid-referenced elevations are useful if you're working with processes relative to sea level. WGS84-referenced elevations are useful for comparing to common datasets you might find such as IceBridge or ICECAP surface elevations referenced to the WGS84 ellipsoid.
