NGS has recently released updated models for transforming ellipsoidal coordinates and orthometric (e.g. NAVD 88) heights. After detecting significant defects in the control data used to create GEOID12, GEOID12A was developed as a replacement. This presentation will discuss the development of changes in the most recent geoid models.
