GEOI: Geoid Values
This record specifies the geoid undulation and deflections of the vertical for a station. Only the values that have not already been defined for the station are actually used (the first record (GEOI or GFIL) defining geoid data for a station is the one actually used).
This record has two possible formats, a long parameter name format, and a short parameter name format. If column 10 contains an asterisk (*) the long name format is expected, otherwise the short name format is expected.
The short parameter format of this record is as follows (from column - to column: description):
The short parameter format of this record is as follows (from column - to column: description):

The short parameter format of this record is as follows (from column - to column: description):
