AS 38.20.060. Characteristics of Zones.

(a) The zones of the Alaska Coordinate System of 1927 have the following characteristics:

(1) Zone 1 is an oblique Mercator projection of the Clarke spheroid of 1866, having an origin at the intersection of parallel 57 00 minutes north latitude and meridian 133 40 minutes west of Greenwich, at which the scale is set one part in 10,000 too small, and through which the axis of symmetry is in geodetic azimuth arc tangent-3/4, reckoned clockwise from south. The origin is assigned values such that all final coordinates will be positive.

(2) Zone 2 is a transverse Mercator projection of the Clarke spheroid of 1866, having a central meridian 142 00 minutes west of Greenwich, on which meridian the scale is set one part in 10,000 too small. The origin of coordinates is at the intersection of the meridian 142 00 minutes west of Greenwich and the parallel of 54 00 minutes north latitude. This origin is given the coordinates: x = 500,000 feet and y = 0 feet.

(3) Zone 3 is a transverse Mercator projection of the Clarke spheroid of 1866, having a central meridian 146 00 minutes west of Greenwich, on which meridian the scale is set at one part in 10,000 too small. The origin of coordinates is at the intersection of the meridian 146 00 minutes west of Greenwich and the parallel 54 00 minutes north latitude. This origin is given the coordinates: x = 500,000 feet and y = 0 feet.

(4) Zone 4 is a transverse Mercator projection of the Clarke spheroid of 1866, having a central meridian 150 00 minutes west of Greenwich, on which meridian the scale is set at one part in 10,000 too small. The origin of coordinates is at the intersection of the meridian 150 00 minutes west of Greenwich and the parallel 54 00 minutes north latitude. This origin is given the coordinates: x = 500,000 feet and y = 0 feet.

(5) Zone 5 is a transverse Mercator projection of the Clarke spheroid of 1866, having a central meridian 154 00 minutes west of Greenwich, on which meridian the scale is set at one part in 10,000 too small.

This origin is given the coordinates: x = 500,000 feet and y = 0 feet.

The origin of coordinates is at the intersection of the meridian 158 00 minutes west of Greenwich and the parallel 54 00 minutes north latitude. This origin is given the coordinates: x = 500,000 feet and y = 0 feet.

(7) Zone 7 is a transverse Mercator projection of the Clarke spheroid of 1866, having a central meridian 162 00 minutes west of Greenwich, on which meridian the scale is set at one part in 10,000 too small. The origin of coordinates is at the intersection of the meridian 162 00 minutes west of Greenwich and the parallel 54 00 minutes north latitude. This origin is given the coordinates: x = 700,000 feet and y = 0 feet.

(8) Zone 8 is a transverse Mercator projection of the Clarke spheroid of 1866, having a central meridian 166 00 minutes west of Greenwich, on which meridian the scale is set at one part in 10,000 too small. The origin of coordinates is at the intersection of the meridian 166 west of Greenwich and the parallel 54 00 minutes north latitude. This origin is given the coordinates: x = 500,000 feet and y = 0 feet.

(9) Zone 9 is a transverse Mercator projection of the Clarke spheroid of 1866, having a central meridian 170 00 minutes west of Greenwich, on which meridian the scale is set at one part in 10,000 too small. The origin of coordinates is at the intersection of the meridian 170 00 minutes west of Greenwich and the parallel 54 00 minutes north latitude. This origin is given the coordinates: x = 600,000 feet and y = 0 feet.

(10) Zone 10 is a Lambert conformal conic projection of the Clarke spheroid of 1866, having standard parallels at north latitude 51 degrees 50 minutes and 53 degrees 50 minutes, along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 176 degrees 00 minutes west of Greenwich and the parallel 51 degrees 00 minutes north latitude.
