SFMC: Scale, Convergence

This record (used only for output text files by GeoLab) contains the point scale factor, elevation factor, and meridian convergence for a 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: SFMC
Columns 010-010: (blank)
Columns 011-022: Station name
Columns 024-037: Point scale factor
Columns 039-054: Elevation factor
Columns 056-071: Combined scale = (Point scale factor + Elevation factor) / 2
Columns 056-059: Degrees of meridian convergence
Columns 061-062: Minutes of meridian convergence
Columns 064-072: Seconds of meridian convergence
Columns 074-080: Map projection name

The long parameter name format is as follows:

Columns 002-005: SFMC
Columns 010-010: * (asterisk)
Columns 011-041: Station name
Columns 043-056: Point scale factor
Columns 058-073: Elevation factor
Columns 075-090: Combined scale = (Point scale factor + Elevation factor) / 2
Columns 075-078: Degrees of meridian convergence
Columns 080-081: Minutes of meridian convergence
Columns 083-091: Seconds of meridian convergence
Columns 093-099: Map projection name
