In order for FieldGenius to provide elevations that represent sea level in the datum accepted for your region and to accurately compute scale factors and transformations, a geoid must be downloaded.

The geoid catalog uses your internet connection to accomplish this step.

Learn more about geoids in MicroSurvey helpdesk.
