Geographic3D to GravityRelatedHeight (NRCan byn) is a geoid model that transforms height values between the local ellipsoid and a local vertical datum. The model data exist in a single .byn file providing a grid of elevation difference values between between the ellipsoid height and the vertical datum at specific latitude and longitude values. The elevation differences at non-grid point locations are interpolated.
