PLO: Latitude, Longitude, & Orthometric Height
This record specifies the ellipsoidal latitude and longitude, and orthometric height of a station. It is used to provide initial coordinates, or to provide 3DC and 3DD observations.
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 name format is as follows:
Columns 002-005: PLO
Columns 007-007: Flag for fixing ellipsoidal latitude
Columns 008-008: Flag for fixing ellipsoidal longitude
Columns 009-009: Flag for fixing ellipsoidal height
Columns 010-010: (blank)
Columns 011-022: Station name
Columns 024-024: Indicator for north (n/N/space) or south (s/S) latitude
Columns 025-027: Degrees of latitude
Columns 029-030: Minutes of latitude
Columns 032-040: Seconds of latitude
Columns 042-042: Indicator for east (e/E/space) or west (w/W) longitude
Columns 043-045: Degrees of longitude
Columns 047-048: Minutes of longitude
Columns 050-058: Seconds of longitude
Columns 060-071: Orthometric height
Columns 073-074: Linear unit name
Columns 076-081: Network layer of station
Columns 083-133: Description of station
The long parameter name format is as follows:
Columns 002-005: PLO
Columns 007-007: Flag for fixing ellipsoidal latitude
Columns 008-008: Flag for fixing ellipsoidal longitude
Columns 009-009: Flag for fixing ellipsoidal height
Columns 010-010: * (asterisk)
Columns 011-041: Station name
Columns 043-043: Indicator for north (n/N/space) or south (s/S) latitude
Columns 044-046: Degrees of latitude
Columns 048-049: Minutes of latitude
Columns 051-059: Seconds of latitude
Columns 061-061: Indicator for east (e/E/space) or west (w/W) longitude
Columns 062-064: Degrees of longitude
Columns 066-067: Minutes of longitude
Columns 069-077: Seconds of longitude
Columns 079-090: Orthometric height
Columns 092-093: Linear unit name
Columns 095-100: Network layer of station
Columns 102-152: Description of station
The flags for fixing coordinates result in a coordinate being free (not fixed) if it is 0 or blank. Any other character results in fixing the coordinate.
