Tools Coordinate plotting tools can aid plotting grid points on maps. The examples below have more information on reading grid references.

A position kilometres west of a central meridian would have an easting ofmetres. The location is Mount Woolnough. The Northing and Easting lines are all numbered.

Grids may be arbitrary, or can be based on specific distances, for example some maps use a one-kilometre square grid spacing. Since, in the UK at least, a 6-figure grid reference identifies a square of metre sides, an 8-figure reference would identify a metre square, and a digit reference a 1-metre square.

Then select the appropriate datum: They refer to the name of the map in question, a practical and quick solution for sharing information.

An 8-digit grid reference is even more accurate how to write a 14 figure grid reference box a 6-digit one and has an accuracy of 10 m2.

In the UTM system, the earth is divided into 60 zones. A six figure coordinate has six figure grid reference an accuracy of m2, indicated in the orange square box. Eastings are always given first.

The grid numbers on the east-west horizontal axis are called Eastings, and the grid numbers on the north-south vertical axis are called Northings.

This article needs additional citations for verification. Eastings are written before Northings. These are added to the four-figure grid reference after the two digits describing the same coordinate axisand thus our six-figure grid reference for the church becomes Plotting a grid reference on a map Learning how to plot a grid reference on a map Plotting a grid reference on a map is the reverse process of reading it on the map.

April Learn how and when to remove this template message A typical map displaying grid reference Grid references define locations in maps using Cartesian coordinates. The grid point is the top of a knoll on a large flat hill top. On an OS map each grid square is 1 km x 1 km or 1 sq km.

The symbols on the map are not precise in any case, for example the church in the example above would be approximately x metres if the symbol was to scale, so in fact, the middle of the black square represents the map position of the real church, independently of the actual size of the church.

Move north until you get to the northing crossing the bottom-left-hand corner of the square you want. The Hill has a six-digit grid reference of Unsourced material may be challenged and removed.

In the UTM system, the vertical lines are called Eastings i. Reference systems Understanding reference systems used by bushwalkers When sharing a grid reference, bushwalkers must be clear on the reference system being used, else the points will not necessarily match up.

This might be used in surveying but is not generally used for land navigating for walkers or cyclists, etc. A GPS unit commonly gives a ten-digit grid reference, based on two groups of five numbers for the Eastings and Northing values.

In this case, the tourist information office is in grid square Bushwalkers often share grid references of campsites or camp caves, obstacles or challenges on a walk, where to get through a cliff line, where to cross a river or what route to take.

The reference is an eight-digit grid reference with a Easting and Northing. And this is the system described here. Hence the six-digit grid reference of Hill is Imagine or draw or superimpose a Romer a further 10x10 grid within the current grid square.

Since the Eastings and Northings are one kilometre apart, a combination of a Northing and an Easting will give a four-digit grid reference describing a one-kilometre square on the ground. Orienteering competitions also provide information on their flag locations using grid coordinates.

To locate a specific building in Little Plumpton, a further two digits are added to the four-digit reference to create a six-digit reference. Next, move north from the bottom-left-hand corner of your grid square and estimate how many tenths your symbol is from this point.

In this instance, the tourist information office is located at Using a GPS to identify and plot locations How to use a GPS to identify and plot your location on a map GPS units are an excellent tool for identifying and plotting locations along a bushwalk.

Sometimes it is necessary to be even more accurate. Put them together to create a six figure grid reference. The reference is a six-digit grid reference with a Easting and Northing.The 6 figure grid reference is therefore Since the map is a new edition map and uses the MGA reference system, the six-digit grid reference is ‘Hilltop MGA’.

Example 3: Hill A 6 figure grid reference puts you in an area bigger than Wembley Football pitch An 8 figure grid reference puts you in an area less than a quarter of Wimbledon’s centre tennis court What is the accuracy of a 6 figure grid reference?

A whole lesson on 4 figure grid references. The group activity is based around the OS maps that my school receives of our local area so you can change these questions if you would like to do it for your local area. Get them to do it with whiteboards and they will love the competition!

(14) FREE; AQA NEW SPEC GCSE: Ecosystems/5(25). Each successive increase in precision (from 6 digit to 8 digit to 10 digit) pinpoints the location by a factor of Since, in the UK at least, a 6-figure grid reference identifies a square of metre sides, an 8-figure reference would identify a metre square, and a digit reference a 1-metre square.

Starting with “0” as the number of the first box – count across from the Easting line to where you are and add this to your Easting number of your four figure grid reference.

Then you do the same with the Northing – starting with “0” in the first box – count up how many squares you are from the bottom northing line of the square. Write this number after the first two digits.

Next, move north from the bottom-left-hand corner of your grid square and estimate how many tenths your symbol is from this mi-centre.com them together to create a six figure grid reference.

In this instance, the tourist information office is located at
