What Geoid model is used within the Verify-QC software?
All versions of Verify-QC use the EGM96 model as the default.
Commencing with v1.08, the EGM08 model is offered as a selectable option (default is EGM96)
A “User” model may also be selected. An estimate of the local geoidal separation must then be entered manually. This option should be used with care since the manual entry must be updated as the vessel changes location.
Information on the EGM Geoid Models can be found at the National Geospatial-Intelligence Agency website which can be accessed by clicking here.
