ANGL: Angle Observation

This record specifies a horizontal angle observation. A horizontal angle is measured at the at-station, from the from-station, and clockwise (towards the right) to the to-station.

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: ANGL
Columns 007-009: Sigma record identifier (see the SIGM record)
Columns 010-010: (blank)
Columns 011-022: At-station name
Columns 024-035: From-station name
Columns 037-048: To-station name
Columns 050-050: Sign (-/+/space) of angle observation
Columns 051-053: Degrees of angle observation
Columns 055-056: Minutes of angle observation
Columns 058-064: Seconds of angle observation
Columns 066-075: Standard deviation of angle observation (seconds)

The long parameter name format is as follows:

Columns 002-005: ANGL
Columns 007-009: Sigma record identifier (see the SIGM record)
Columns 010-010: * (asterisk)
Columns 011-041: At-station name
Columns 043-073: From-station name
Columns 075-105: To-station name
Columns 107-107: Sign (-/+/space) of angle observation
Columns 108-110: Degrees of angle observation
Columns 112-113: Minutes of angle observation
Columns 115-121:Seconds of angle observation
Columns 123-132: Standard deviation of angle observation (seconds)
