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.

Columns 002-005: GEOI
Columns 010-010: (blank)
Columns 011-022: Station name
Columns 024-024: Sign (-/+/space) of north/south deflection
Columns 025-027: Degrees of north/south deflection
Columns 029-030: Minutes of north/south deflection
Columns 032-040: Seconds of north/south deflection
Columns 042-042: Sign (-/+/space) of east/west deflection
Columns 043-045: Degrees of east/west deflection
Columns 047-048: Minutes of east/west deflection
Columns 050-058: Seconds of east/west deflection
Columns 060-071: Geoid undulation
Columns 073-074: Linear unit name

The long parameter name format is as follows:

Columns 002-005: GEOI
Columns 010-010: * (asterisk)
Columns 011-041: Station name
Columns 043-043: Sign (-/+/space) of north/south deflection
Columns 044-046: Degrees of north/south deflection
Columns 048-049: Minutes of north/south deflection
Columns 051-059: Seconds of north/south deflection
Columns 061-061: Sign (-/+/space) of east/west deflection
Columns 062-064: Degrees of east/west deflection
Columns 066-067: Minutes of east/west deflection
Columns 069-077: Seconds of east/west deflection
Columns 079-090: Geoid undulation
Columns 092-093: Linear unit name
