#Define grid mapping series#

The more digits included in the coordinate string, the higher the precision level. Result in several formats, such as degrees-minutes-seconds, degrees-decimal minutes, and decimalДegrees. Minutes can be subdivided into 60 seconds, for the purpose of increased precision level. Latitude/Longitude coordinate must include Latitude and Longitude parts in conjunction to define aДЇollowing the sexagesimal, base 60, system, degrees can be subdivided into 60 minutes, and MovingД®ast and west of the Prime Meridian, longitudes increase in number from 0В° to 180В°. Angles of longitude are also measured from theД¬enter of the Earth and are referenced starting at the Prime Meridian, which is assigned 0В°. Increase in number from 0В° to 90В° at the two poles. Moving north and south of the Equator, latitudes Starting at the Equator, which is assigned 0В°. ItД¬onsists of angles of latitude that are measured from the center of the Earth and are referenced Latitude/longitude is a geographic reference system used to define positions on the Earth. Value of this position is 15SWC8081751205. The magenta arrows show how MGRS Easting and Northing valuesДЄre determined from within the 100,000-meter grid square. The 100,000-meter grid square 'WC' for WGS-84 generallyД¬oincides with the grid square 'WN' for Clarke 1866.The other is used for older ellipsoids associated with the local Generally, one scheme is used for WGS-84, and There are two lettering schemes for the 100,000-meter grid Northing, and including more numbers depending on desired precision With the numbers in the ten-thousands place in the Easting and Within the MGRS coordinate correspond to the UTM values starting The seventh character is the keypad 'key' number The first six characters comprise the 15-minute quadrantДesignation. Each 5-minute by 5-minute area, or keypad 'key' is identified by a seven-characterДesignation.The graphical representation of a 15-minute quadrant with numbered 5-minute by 5-minute The areas are numbered sequentially, from west to east, starting with the northernmostД«and.Each 15-minute quadrant is divided into nine 5-minute by 5-minute areas:.The sixth character is the quadrant number. The first five characters comprise the 30-minute cell designation. Each quadrant is identified by a six-character designation (ex.The southwest quadrant is '3' the southeast quadrant is '4'. Specifically, the northwest quadrant is '1' the northeast quadrant is '2' The quadrants are numbered sequentially, from west to east, starting with the.Each 30-minute cell is divided into four 15-minute by 15-minute quadrants:.The bands are lettered from AA to QZ (omitting I and O) so that 90В° 00'S to 89В° 30'S is band AA 89В° Beginning at the south pole and proceeding northward, The fourth and fifth charactersДesignate a 30-minute wide latitudinal band. Beginning with the 180В° meridian and proceedingД®astward, the bands are numbered from 001 to 720, so that 180В° E to 179В° 30'W is band 001 179В° 30'W toДЎ79В° 00'W is band 002 and so on. The first three charactersДesignate a 30-minute wide longitudinal band. Each cell is identified byДЄ five-character designation (ex. GARS divides a surface of the earth into 30-minute by 30-minute cells. Longitude expressed in sexagesimal (base 60) numbering system. The standard geographic reference system used by NGA and DoD are latitude and West of the reference meridian (Greenwich Prime Meridian) to another meridian that passes through Longitude (О› - lambda) is the angle east or Latitude (П† - phi) is theДЄngle between the equatorial plane and the straight line that passes through the point in questionДЄnd the center of the reference shape (WGS84 ellipsoid). A geographic coordinate definingДЄ location is usually expressed in angular units of latitude and longitude. Which to reference locations on the Earth using a system of angles.

Standard grid reference systems used by NGA and DoD are Of x and y values expressed in linear units. A grid coordinate defining a location consists of and is written as an ordered pair Locations on the Earth's surface using a two dimensional Cartesian coordinate system referenced to a GridA grid, or more specifically a Grid Reference System, is a means by which to reference
