PL: Latitude & Longitude

This record specifies the ellipsoidal latitude and longitude of a station. It can be used to provide initial coordinates, or to provide 2DC observations. It 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 name format of this record is as follows (from column - to column: description):            
  • 002-005: PL
  • 007: Flag for fixing ellipsoidal latitude
  • 008: Flag for fixing ellipsoidal longitude
  • 009: Flag for fixing ellipsoidal height
  • 010: (blank)
  • 011-022: Station name
  • 024: Indicator for north (n/N/space) or south (s/S) latitude
  • 025-027: Degrees of latitude
  • 029-030: Minutes of latitude
  • 032-040: Seconds of latitude
  • 042: Indicator for east (e/E/space) or west (w/W) longitude
  • 043-045: Degrees of longitude
  • 047-048: Minutes of longitude
  • 050-058: Seconds of longitude
  • 076-081: Network layer of station
 
The long name format of this record is as follows (from column - to column: description): 
  • 002-005: PL
  • 007: Flag for fixing ellipsoidal latitude
  • 008: Flag for fixing ellipsoidal longitude
  • 009: Flag for fixing ellipsoidal height
  • 010: * (asterisk)
  • 011-041: Station name
  • 043: Indicator for north (n/N/space) or south (s/S) latitude
  • 044-046: Degrees of latitude
  • 048-049: Minutes of latitude
  • 051-059: Seconds of latitude
  • 061: Indicator for east (e/E/space) or west (w/W) longitude
  • 062-064: Degrees of longitude
  • 066-067: Minutes of longitude
  • 069-077: Seconds of longitude
  • 095-100: Network layer 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.
