WILLIAM DONALD SCHAEFER, Governor                   Ch. 196

The system of plane rectangular coordinates which has been
established and adopted by the [United States Coast and] NATIONAL
Geodetic Survey for defining and stating the positions or
locations of points on the surface of the earth within the State
of Maryland shall be hereafter known and designated as the
"Maryland coordinate system," and it shall be so designated in
any land description in which it may be used.

20.

The plane rectangular coordinates of a point on the' earth's
surface, to be used in expressing the position or location of
such point on the above system, shall consist of two distances,
expressed in [feet] METERS and decimals thereof. One of these
distances, to be known as the ["x coordinate,"] "EASTINGS" shall
give the position in an east-west direction; the other, to be
known as the ["y coordinate,"] "NORTHINGS" shall give the
position in a north-and-south direction. These coordinates shall
be made to depend upon and conform to the plane rectangular
coordinates of the triangulation and traverse stations of the
[United States Coast and] NATIONAL Geodetic Survey within the
State of Maryland, as those coordinates have been determined by
the said survey.

21.

For purposes of more precisely defining the Maryland
coordinate system, the following definition by the [United States
Coast and] NATIONAL Geodetic Survey is adopted:

The Maryland coordinate system is a Lambert CONIC conformal
projection of the [Clarke spheroid of 1866,] GEODETIC REFERENCE
SYSTEM OF 1980, having standard parallels at north latitudes 38
decrees 18' and 39 degrees 27, along which parallels the scale
shall be exact. The origin of coordinates is at the intersection
of the meridian 77 degrees 00' west longitude and the parallel 37
degrees [50'] 40' north latitude. This origin is given the
coordinates: [x] EASTING = [800,000 feet] 400,000 METERS and [y]
NORTHING = 0 [feet] METERS.

FOR THE MARYLAND COORDINATE SYSTEM, THE UNIT USED TO CONVERT
FEET TO METERS SHALL BE THE UNITED STATES SURVEY FOOT WHICH IS
39.37/12 FEET FOR EACH METER.

The position of the Maryland coordinate system shall be as
marked on the ground by triangulation or traverse stations
established in conformity with the standards adopted by the
[United States Coast and] NATIONAL Geodetic Survey for
first-order and second-order work, whose geodetic positions have
been rigidly adjusted on the North American [datum] DATUM of
[1927] 1983 and whose plane coordinates have been computed on the
system herein defined.
