**Asked by: Jorge Murray**

Score: 4.1/5 (45 votes)

**Eastings are written before Northings**. Thus in a 6 digit grid reference 123456, the Easting component is 123 and the Northing component is 456, i.e. if the smallest unit is 100 metres, it refers to a point 12.3 km east and 45.6 km north from the origin.

Also asked, In which order do you read the Eastings and Northings?

Four-figure grid references

When giving a four-figure grid reference, you should

**always give the eastings number first and the northings number second**, very much like when giving the reading of a graph in school, where you give the x coordinate first followed by the y.

Accordingly, Where are Eastings and Northings measured from?. Eastings are

**referenced from the central meridian of each zone**, & northings from the equator, both in metres. To avoid negative numbers, 'false eastings' and 'false northings' are used: Eastings are measured from 500,000 metres west of the central meridian.

Likewise, people ask, Are Eastings vertical or horizontal?

The

**vertical lines**are called eastings. They are numbered - the numbers increase to the east. The horizontal lines are called northings as the numbers increase in an northerly direction.

What is a false easting?

False easting is

**a linear value applied to the origin of the x coordinates**. False northing is a linear value applied to the origin of the y coordinates. False easting and northing values are usually applied to ensure that all x and y values are positive.

### What is the difference between Eastings and Northings?

The terms easting and northing are geographic Cartesian coordinates for a point. Easting refers to the eastward-measured distance (or the x-coordinate), while **northing refers tothe northward-measured** distance (orthe y-coordinate).

### Are latitudes Northings?

For example UTM is a common projection, a location is identified with easting and northing and the units are in meters. I have drawn a map below to illustrate the above explanation. The black grid lines are Latitude and Longitude and **in red are the Eastings and Northings**.

### Which way do Northings run?

Northings. Northings are lines that run **across the map horizontally**. They increase in number the further you move north (or up the map).

### How do I find Eastings and Northings on Google maps?

- Open Google Earth.
- At the top, click Google Earth. Preferences.
- Click 3D View. Then, under "Show Lat/Long," choose a display format.
- Click OK. Coordinates will be displayed in the lower right corner.

### How do you convert Eastings and Northings to grid reference?

**To convert a National Grid Reference to Eastings and Northings:**

- Remove the two letters at the beginning of the reference: e.g. NS1234 becomes 1234.
- Split the reference into it's East and North components: e.g. 12 East and 34 North.
- Work out the numerical reference for the two letters: e.g. NS = 200km East and 600km North.

### How accurate is a 6 figure grid reference?

Six figure grid references are commonly used for topographic maps with a scale of 1:50,000. ... On a 6-figure grid reference the last digit refers to a tenth of the distance between the 1km grid reference lines, so the reference is **only accurate to within 100 metres**.

### How do Eastings and Northings work?

Easting and northing are **geographic Cartesian coordinates** for a point. Easting is the eastward-measured distance (or the x-coordinate) and northing is the northward-measured distance (or the y-coordinate). ... Easting and northing coordinates are commonly measured in metres from the axes of some horizontal datum.

### What are Northings?

Definition: Northings are **numbered horizontal lines found on maps**. The equator is a northing line, and additional invisible lines surround the Earth moving away from the equator.

### Are Eastings and Northings the same as latitude and longitude?

"Easting and northing" are the standard names **for the x and y coordinates** in any projected (i.e. planar) coordinate system. Additionally, "latitude and longitude" are the standard names for the coordinates in any unprojected (i.e. geographic) coordinate system.

### How do I find my national grid reference?

**How to find a National Grid Reference**

- When you find an object, place it in a bag and write on the location of the findspot. ...
- Look at a 1:25000 scale OS map. ...
- Locate the findspot on the map, and then read the National Grid Reference; the first part will be the prefix (2 letters).

### Whats are Eastings?

### Is y a latitude?

1 Answer. For coordinates captured using a GPS, or by any means, longitude is the X value and **latitude is the Y value**. These are for a geographic coordinate system and have units of degrees.

### What are Eastings and Northings in topographic map?

### What is meant by grid references?

A grid reference is **a location on a map**, which is found using the northing and easting numbered lines. Grid references are useful for helping a map user to find specific locations. Grid Reference. Northings. Eastings.

### What is a false origin?

In regards to map projections, a false origin is **an adjustment of that original origin at (0,0) to a different location either east or north of the zone from which measurements are being taken**. It is commonly placed in the south west corner.

### What coordinate does False Easting apply?

False easting is needed to **avoid negative x-coordinates west of each zone's central meridian**. False northing is needed to avoid negative y-coordinates for all locations in southern hemisphere zones. (The value of ten million meters guarantees that every point above the south pole has a positive y-value.)

### What is UTM mapping?

UTM is the acronym **for Universal Transverse Mercator**, a plane coordinate grid system named for the map projection on which it is based (Transverse Mercator). The UTM system consists of 60 zones, each 6-degrees of longitude in width. ... One system is no more or less accurate than the other.

### What are Eastings and Northings in geography?

The terms easting and northing are geographic Cartesian coordinates for a point. Easting refers to the eastward-measured distance (or the -coordinate), **while northing refers to the northward-measured distance (or the -coordinate)**. The orthogonal coordinate pair are commonly measured in meters from a horizontal datum.
