EDIS: Ellipsoidal Distance Observation

This record specifies an ellipsoidal distance (measured along the surface of the reference ellipsoid) observation.

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: EDIS
Columns 007-009: Sigma record identifier (see the SIGM record)
Columns 010-010: (blank)
Columns 011-022: Station name of from-station
Columns 024-035: Station name of to-station
Columns 050-064: Distance observation
Columns 066-075: Standard deviation of distance observation
Columns 077-078: Linear unit name

The long parameter name format is as follows:

Columns 002-005: EDIS
Columns 007-009: Sigma record identifier (see SIGM record)
Columns 010-010: * (asterisk)
Columns 011-041: Station name of from-station
Columns 043-073: Station name of to-station
Columns 075-089: Distance observation
Columns 091-100: Standard deviation of distance observation
Columns 102-103: Linear unit name
