What coordinate system does the UK use?
The technical name for the National Grid coordinate system is OSGB36 National Grid. The OSGB36 part of the name, which stands for Ordnance Survey Great Britain 1936, refers to the geodetic datum used; the National Grid part refers to the map projection and grid referencing convention for eastings and northings.
How do I find out my grid reference?
- Click “Grid Reference Tools” and choose “Get Grid Reference from Map”. By clicking on the desired location, the 6-figure Grid reference will be shown.
- Click “Location Search Tools” and enter a place name (this does not work with post codes). The map will centre on the place name, if found.
What is a grid reference grade 4?
Grid references are an easy way of accurately locating any point on a map. The grid on a map consists of two sets of lines, one set running north-south (called northings) and one set running east- west (called eastings).
How are grid references written?
A grid reference shows a particular location on a map using 4 digits or 6 digits. The grid reference depends on eastings and northings. On a map, northings appear as horizontal lines. When writing grid references, eastings are written before northings.
What UTM zone is London?
UTM zone 30U
Maps of UTM zones such as that provided by dmap.co.uk confirm that London is in UTM zone 30U.
What type of coordinate system is the British national grid?
The Ordnance Survey National Grid reference system (also known as British National Grid (BNG)) is a system of geographic grid references used in Great Britain, distinct from latitude and longitude.
How do I get a grid reference UK?
- Start at the left-hand side of the map and go east until you get to the bottom-left-hand corner of the square you want. Write this number down.
- Move north until you get to the bottom-left corner of the square you want.
How do I find my 6 digit grid reference?
Six-figure grid reference
- First, find the four-figure grid reference but leave a space after the first two digits.
- Estimate or measure how many tenths across the grid square your symbol lies.
- Next, estimate how many tenths up the grid square your symbol lies.
- You now have a six figure grid reference.
What is area and grid reference?
A grid is a system of intersecting parallel lines. Location can be described by a four-figure reference (area reference) or a six-figure reference (grid reference). The area reference gives a general location, while the grid reference provides an accurate location for a place or feature.
What is the difference between 4 and 6 figure grid references?
National Grid reference numbers four-figure grid reference, such as ’19 45′, indicates a 1 km by 1 km square on the map; and. six-figure grid reference, such as ‘192 454’, indicates a 100 m by 100 m square on the map.

What is a four-figure grid reference?
In a four-figure grid reference, four-figure or four digits are used to locate something on a map. In every map there are both horizontal lines which are easting and vertical line, i.e, northing crosses each other and create a grid square.
How do you give a grid reference for stairs?
They are numbered – the numbers increase to the east. The horizontal lines are called northings as the numbers increase in an northerly direction. When you give a grid reference, always give the easting first: “Along the corridor and up the stairs”. Four-figure grid references can be used to pinpoint a location to within a square.
What is the purpose of a grid on a map?
A grid of squares helps the map-reader to locate a place. 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. When you give a grid reference, always give the easting first: “Along the corridor and up the stairs”.
