Latitude and Longitude coordinate system

Latitude and longitude coordinates make up our geographic coordinate system. A geographic coordinate system defines two-dimensional coordinates based on the Earth’s surface. It has an angular unit of measure, prime meridian and datum (which contains the spheroid).

Latitude lines run east-west and are parallel to each other. If you go further north, latitude values increase. Finally, latitude values (Y-values) range between -90 and +90 degrees.

But longitude lines run north-south. They converge at the poles. And its X-coordinates are between -180 and +180 degrees.

The equator is where we measure north and south. For example, everything north of the equator has positive latitude values. Whereas, everything south of the equator has negative latitude values. Most horizontal datums define a zero line at the equator.

The Greenwich Meridian (or prime meridian) is a zero line of longitude from which we measure east and west. In fact, the zero line passes through the Royal Observatory in Greenwich, England, which is why we call it what it is today. In a geographical coordinate system, the prime meridian is the line that has 0° longitude.

UTM Coordinate system

Universal Transverse Mercator (UTM) Coordinate system is based on Mercator projection. But instead of single map projection, UTm divide earth into 60 zones and project individually.

Start with a sphere or ellipsoid because that is the true form of the Earth. Peel it like an orange evenly into sixty segments called “zones”. Flatten each one of these zones. What’s the result? It’s the Universal Transverse Mercator (UTM) projection!

Universal Transverse Mercator Projection

The Universal Transverse Mercator projection is based on the cylindrical Transverse Mercator projection. The cylinder in the Transverse Mercator projection is tangent along a meridian (line of longitude) or it is secant, in which case it cuts through the earth at two standard meridians.

In the UTM projection the transverse cylinder rotates by 6° increments, thus creating 60 (360° / 6°) strips or projection zones. In such a projection, instead of projecting the complete globe into a flat surface, each of the 60 strips or zones gets projected onto a plane separately, therefore minimizing scale distortion within each zone.

The Meridian at the centre of each zone is called the central meridian. The cylinder is secant in the UTM projection; it intersects the globe creating two standard meridians that are 180 km to each side of the central meridian.

 

Easting

The easting coordinate of a point is measured from the false origin 500000 meters to the west of the central meridian of the UTM zone. Within a zone, easting values increase towards east. A point lying 8 meters east of central meridian has an easting of 500000 + 8 = 500008mE. The easting of a point 350m west of central meridian would be 500000 – 350 = 499650mE. The east-west distance between two points is obtained by the difference of their easting values. The distance between the above points is 500008 – 499650 = 358m.

Longitude lines are furthest apart at the equator, where latitude is zero. Therefore the maximum width of a UTM zone occurs on the equator. Depending on the datum and the chosen ellipsoid, an approximate range for the easting values can be calculated.

In general, the easting values cannot be larger than 834000m and smaller than 166000m. As a result, an easting coordinate is always a six digit number. Sometimes in GPS systems and GIS software, the easting values are preceded with a 0 in order to represent them as 7 digit numbers.

Northing

A northing value in northern hemisphere specifies the number of meters a point is located north of the equator. The northing of a point south of the equator is equal to 10,000,000m minus its distance from the equator. In both northern and southern hemispheres, northing values increase from south to north.

A point south of the equator with a northing of 7587834mN is 10,000,000 – 7587834 = 2412166m south of the equator. A point located 34m south of the equator has a northing of 9999966mN, while a point 34m north of the equator has a northing of 0000034mN. The north-south distance between two points north of equator with northings of 4867834mN and 4812382mN is 4867834 – 4812382 = 55452m.

Depending on the datum and the chosen ellipsoid, an approximate range for the northing values can be calculated. In the southern hemisphere, the northing values range from 10,000,000m at the equator to approximately 1100000m at the 80th south parallel. In the northern hemisphere, the northing values stretch from 0m at the equator to around 9350000m at the 84th north parallel. If the northing values are less than 7 digits, they will usually be preceded with 0(s) to represent them as 7 digit numbers.

World Geodetic System (WGS84)

The Global Positioning System uses the World Geodetic System (WGS84) as its reference coordinate system.

It comprises of a reference ellipsoid, a standard coordinate system, altitude data and a geoid. Similar to the North American Datum of 1983 (NAD83), it uses the Earth’s centre mass as the coordinate origin.

Pinpoint Your Position Using WGS84

When you need to accurately enter coordinates in a GIS, the first step is to uniquely define all coordinates on Earth.

This means you need a reference frame for your latitude and longitude coordinates because where would you be on Earth without having reference to it?

Because the Earth is curved – and in GIS we deal with flat map projections – we need to accommodate both the curved and flat views of the world. Surveyors and geodesists have accurately defined locations on Earth.
