USGS CMG "Total station" Definition

UTM x/y coordinates are a rectangular coordinate system with units in meters from the equator (the "y" value) and meters from a central meridian (the "x" value).
The central meridian defines a 6 degree wide zone.
The zone must beknown for uniqueness.
Zone 1 starts at the International Date Line, has a central meridian 3 degrees counterclockwise around the earth from there (-177d), and continues another 3degrees.
Zone 2 has a central meridian of -171d (-177 - 6), and so on around the globe. Latitudes and longitudes
Latitudes are parallel to the Equator and range from -90 degrees (South Pole) to+90 degrees (North Pole).
The northern hemisphere has positive latitudes.
The southern hemisphere has negative latitudes.
Longitudes are perpendicular to the Equator are range from -180 degrees (International Date Line) to +179.99999... degrees (just west of the International Date Line).
Under this convention -- the western hemisphere has negative longitudes and the eastern hemisphere has positive longitudes.

Total station information occurs in the InfoBank as:

scattered	< Activity-ID >.utm files containing UTM X,Y,Z information.
metadata	information about Total station inventory of gear, deployment of gear, operation of gear, and magnetic media.
