TMER: Transverse Mercator Map Projection

This record specifies a transverse Mercator (including UTM and 3-degree TM) map projection to be used for transformations between ellipsoidal and mapping coordinates. Any number of TMER 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 TMER record with a QUAD record. Note that the XTMR (extended Transverse Mercator) record allows the specification of seconds of origin latitude and longitude (in addition to degrees and minutes), whereas the TMER record only allows the specification of degrees and minutes.

The format of the TMER record is as follows:

Columns 002-005: TMER
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 023-023: North (n/N/ ) or south (s/S/-) indicator for origin latitude
Columns 024-026: Degrees of origin latitude
Columns 028-029: Minutes of origin latitude
Columns 031-042: Northing of origin (false northing)
Columns 044-055: Easting of origin (false easting)
Columns 057-068: Scale at origin
Columns 070-071: Linear unit name
