# How to write a 14 figure grid reference finder

Temple asserts that Zhang Heng should also be credited as the first to establish the mathematical grid in cartography, as evidenced by his work in maps, the titles of his lost books, and the hint given in the Book of Later Han i. 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.

To obtain grid references from Street Map, follow these steps: Imagine or draw or superimpose a Romer a further 10x10 grid within the current grid square. Northing values are given by the metres north, or south in the southern hemisphere of the equator.

Easting values are established as the distance from the central meridian of a zone. Click on the hand, then click on the map.

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.

When reading a grid reference, Eastings always come first, followed by the Northings. Most maps also include the Longitude and Latitude of the map at the corners i. To find a grid reference and also latitude and longitudefollow these steps: Hence the six-digit grid reference of Hill is Summary parameters of the coordinate system[ edit ].

Their accessibility is a bit low Since all objects on a map remain the same relative to each other between the two systems, bearings do not change.

It just depends how you like to work, but the websites can be more accurate and clearly require less desk space. 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 area of error is much smaller than the search area provided by a four-digit grid reference. In an ideal world, all finders would have a handheld GPS device, and would log a 12 figure grid reference at the time of finding an object.

This article needs additional citations for verification. Users must also be clear on the reference system used. Grid references may be written with or without spaces; e. Then select the appropriate datum: Then measure how far along the grid the lines are.

In this example, since the hill has no name it can be called Hill There are four of these which contain significant land area within Great Britain: The Hill has a six-digit grid reference of As a general rule, all the new series maps have an aerial photo image on the reverse.

You need to click on the map where you found your object, or as close as possible. A four digit grid reference 2 digits for the Easting, and 2 for the Northing is a crude measure of the location with an accuracy of one square kilometre.

The more digits added to a grid reference, the more precise the reference becomes. The basic premise for this is that the square is broken down into 10 segments by 10 segments or squaresnumbered from 09 from the southwest corner horizontally and vertically. A position kilometres west of a central meridian would have an easting ofmetres.

You have the option to display Ordnance Survey maps current and an out of copyright version side by side with an array of layers on a Google map and overlay various types of grid.

Major Easting lines are 04, 05, 06, etc. We ask that you provide a 6 figure grid reference as a minimum, this means the location is pinned down to a m square.Lesson 4 Grid Reference Systems 33 The UTM grid system divides Figure The Military Grid Reference System.

Courtesy of CACI ultimedescente.com, you would write this grid coordinate as YFYou have now correctly located a point on the map (Spot Elevation ) to the nearest. UK National Grid Map Reference Conversion for any location by simply right-clicking on our map. Postcode finder and bulk conversion tools.

UK Grid Reference Finder.

Advertisement. Instructions: Right-click (or Tap) on the Map to Display the Grid Reference and Location Information. 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.

In order to give a standard 6-figure grid reference from a figure GPS readout, the 4th, 5th, 9th and 10th digits must be omitted so it is important not. The Ordnance Survey National Grid reference system is a system of geographic grid The most common usage is the six figure grid reference, employing three digits in each coordinate to eastings then northings in metres, measured from the southwest corner of the SV square.

Note that 14 digits may be required for locations in. In order to obtain an 8 figure grid reference, you need to carry out the exact same procedure to obtain a 6 figure grid reference, dividing your grid square into tenths, but then further sub-divide the 6 figure tenth in which your location lies into further tenths (the 8 figure tenths).

How to plot a National Grid Reference. This forms the prefix of the National Grid Reference. Figure 1: The Grid layout of Great Britain.

These grid squares can then be broken down into more squares, of 10 km by 10 km. This is shown for grid square SP below.
