Coordinate Systems and Map Projections
There are several ways to refer to a coordinate system. Some people casually refer to any coordinate system as a "projection", but this is not strictly true.
Coordinated Universal Time converting between UTC and AM/PM time
Coordinated Universal Time (UTC) can be considered equivalent to Greenwich Mean Time (GMT) (when fractions of a second are not important).
coordinate geometry traverse
[ESRI software] In Survey Analyst, a process of computing a sequence of survey point locations starting from an initial known point.
Coordinate systems and projections are fundamental elements of mapping. These result from the need to reproject the earth's round shape [technically a geoid, not a sphere] on a flat plane.
Coordinate Systems
Once map data are projected onto a planar surface, features must be referenced by a planar coordinate system.
Coordinate Systems
General.
As described under map projections, traditional coordinate systems are based on a flat coordinate system.

Coordinates: A set of numbers that describe your exact location on the earth's surface. Latitude/longitude (lat/long) coordinates are the most typical lines of reference and are an important part of the USGS topographical mapping system.

Coordinates are used to define location or distribution of physical quantities which are scalars, vectors, or tensors.
[coordinate systems] A group of planar coordinate systems based on the division of the United States into more than 130 zones to minimize distortion caused by map projections.
Projected Coordinate System Management
Bentley PowerMap Field handles data in standard or customized projected coordinate systems. This capability allows you to combine data of dissimilar projections to conform to your map projection standards.

Projected Coordinate Systems
During the time that Sir Issac Newton (and others) brought to the shape of the earth into public light in the early 18th century, topographic surveys of large regions were carried out.
Using the Latitude Longitude Coordinate System
The latitude longitude coordinate system uses angular measurements to describe a position on the surface of the earth.
Coordinate Thinning
Coordinate thinning involves the weeding or reduction of coordinate pairs, e.g. X and Y, from arcs. This function is often required when data has been captured with too many vertices for the linear features.
Coordinate System
A reference system for defining points on the earth's surface. A coordinate system can be planar (flat) or nonplanar (spherical). The Cartesian system (x,y) is an example of a planar coordinate system.
Coordinate Tool
The Coordinate tool supports Military Grid Reference System (MGRS) and coordinate conversion.
Coordinate: A set of numbers that designate location in a given reference system, such as x,y in a planar coordinate system or an x,y,z in a three-dimensional coordinate system.
coordinate system - A system to measure horizontal and vertical distances so that a geographic feature true position can be established in relation to an accepted public reference system such as State Plane or Universal Transverse Mercator (UTM) ...
coordinate system
A reference system used to measure horizontal and vertical distances on a planimetric map.
Coordinate System - A fixed reference framework superimposed onto the surface of an area to designate the position of a point within it by using x and y coordinates.

Coordinate Systems
Latitudes and Longitudes
Although the Earth is a three-dimensional object, when supposed spherical its surface has a constant radius, so any point on it is uniquely identified using a polar two-coordinate system.

Coordinates
A set of numbers that describes your location on or above the earth. Coordinates are typically based on latitude/longitude lines of reference or a global/regional grid projection (e.g., UTM, MGRS, Maidenhead).

UTM Coordinate System, based on the Universal Transverse Mercator map projection, is a planar locational reference system which provides positional descriptions accurate to 1 meter in 2,500 across the entire earth's surface except the poles.
Plane coordinate systems are used to locate data on the map plane. E.g. any point on the map plane can be located by means of two-dimensional cartesian (or rectangular) coordinates (x,y) or two-dimensional polar coordinates ( a,d ).
Polar coordinate system

[edit] Coordinate systems in space
The locations of points in three-dimensional space are most conveniently described by three cartesian or rectangular coordinates, X,Y and Z.
Planar Coordinate System: A coordinate system drawn on a flat surface, or plane. Planar coordinates are usually expressed as pairs of rectangular X,Y values.
Earth's Coordinate System
The first step in converting the information contained in the real-world onto a 'piece of paper' was to devise a system where everything could be uniquely located in that world.

UTM coordinates are recorded in meters. The UTM northing coordinate (the Y coordinate) for a feature is the distance in meters north from the equator to the feature.
UTM coordinates are typically given with the zone first, then the easting, then the northing. So, in UTM coordinates, Red Hill is located in zone twelve at 328204 E (easting), 4746040 N (northing).
