The WGS84-based Universal Transverse Mercator (UTM) grid Zone 51N as specified in DMA TM8358.2, a longitudinal zone of 6 arc degrees in width located between 120 and 126 arc degrees geodetic longitude and 0 and 84 arc degrees geodetic latitude in the Northern hemisphere.
WGS84E_UTM51N
UTM Zone 51N (WGS84)
On large-scale maps an overlap of approximately 40 kilometres on either side of the meridian separating adjacent UTM grid zones is provided although this overlap is not intended to be used in giving a grid reference; such UTM-to-UTM grid zone overlaps are known as "range extension".

WGS84E_2D
World Geodetic System 1984 - Geographic 2D
Since its establishment for epoch 1984, additional higher accuracy reference frame realizations have been established based on specific Global Positioning System (GPS) weeks (for example: Week 873, denoted as "G873"); these revised realizations of the reference frame are generally only important to applications requiring centimeter-level horizontal positioning accuracy.

A two-dimensional geodetic ellipsoidal coordinate system in which position is specified by geodetic latitude and geodetic longitude.
GeoEllipsoidal
Geodetic Ellipsoidal
The angle from the equatorial plane to the perpendicular to the ellipsoid through a given point with northwards treated as positive. [ISO 19111:2007]
GeodeticLatitude
Geodetic Latitude
The axis direction is positive towards the pole about which the Earth rotates in a counter-clockwise direction. It is symbolized using the small Greek letter phi.
Lat
north
The angle from the prime meridian plane to the meridian plane of a given point with eastwards treated as positive. [ISO 19111:2007]
GeodeticLongitude
Geodetic Longitude
The axis direction is positive in the direction of the Earth's rotation. It is symbolized using the small Greek letter lambda.
Lon
