Ideally, the most commonly used type of coordinate system consists of three imaginary axes that intersect at a common point known as the origin. The axes are labeled alphabetically as x, y and z. They are used to determine the location of a point in the three-dimensional space.

A complete definition of a coordinate system requires the following points given below: 1 It is the projection that can be used to draw the earth on a flat map. 2 Location of the origin. 3 The units that can be used to measure the distance from the origin.
Horizontal coordinate systems are often of three types : geographic, projected, and local.
The prototypical example of a coordinate system can be the Cartesian Coordinate System. In the plane, any two perpendicular lines are chosen and then the coordinates of a point are taken to be the signed distances to the lines.
The region XOY is known as the first quadrant. The region X’OY is known as the second quadrant. The region X’OY’ is known as the third quadrant. The region Y’OX is known as the fourth quadrant. These are the quadrants of coordinate system.
1. The coordinate plane is also known as a Two- dimensional plane.
Longitude and latitude are a special kind of coordinate system, known as a spherical coordinate system , since they identify points on a sphere or globe. However, there are many other coordinate systems utilized in different places round the world to spot locations in the world . All of those coordinate systems place a grid of vertical and horizontal lines over a flat map of some part of the world .
A geographic frame of reference uses longitude and latitude expressed in decimal degrees. For instance , WGS 1984 and NAD 1983 are the foremost common datums today. Before 1983, NAD27 was the foremost common datum.
Objectives: • Learning the basic properties and usesof coordinate systems • Understanding the differencebetween geographic coordinates and projected coordinates •Getting familiarwith different types of map projections •Managing and troubleshootingcoordinate systems of feature classes and images
A:We should choose a map projection that preserves the propertiesappropriate for the application, choosing from the following properties: 1. Shape 2. Area 3. Distance 4. Direction
for mapping • It can be horizontal or vertical
No flat map can be both equivalent & conformal.
To make a coordinate system useful, we need to be able to reference any location in a spatial dataset to a location in the real world
Common Coordinate System used in Georgia (Uses NAD 83 / Measuring units in meters / False easting at 200,000 m for east zone and 700,000 m for west zone
State Plane coordinate system has the least distortion (In most cases UTM will work just as well as State Plane)
