OMER: Oblique Mercator Map Projection

This record specifies an Oblique Mercator map projection to be used for transformations between ellipsoidal and mapping coordinates. Any number of OMER records can be used, each specifying a map projection for a specific area (quadrangle). The area (quadrangle) of validity for a map projection may be specified by preceding the OMER record with a QUAD record.

The format of the OMER record is as follows:

Columns 002-005: OMER
Columns 007-013: Map projection name (any text)
Columns 015-015: East (e/E/space) or west (w/W/-) indicator for central meridian
Columns 016-018: Degrees of central meridian longitude
Columns 020-021: Minutes of central meridian longitude
Columns 023-031: Seconds of central meridian longitude
Columns 033-033: North (n/N/space) or south (s/S/-) indicator for origin latitude
Columns 034-036: Degrees of origin latitude
Columns 038-039: Minutes of origin latitude
Columns 041-049: Seconds of origin latitude
Columns 051-051: Sign (-/+/space) of origin azimuth
Columns 052-054: Degrees of origin azimuth
Columns 056-057: Minutes of origin azimuth
Columns 059-065: Seconds of origin azimuth
Columns 067-078: Northing of origin (false northing)
Columns 080-091: Easting of origin (false easting)
Columns 093-104: Scale at origin
Columns 106-107: Linear unit name
