How do you write a grid reference?
- 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.
What is the rule for finding a grid reference?
In a grid reference, we give the eastings first and then the northings. That means that when you find your point on the map, you must go along to the east first and then move up second. Some people remember the order by saying ‘along the corridor and up the stairs’!
How do you write a 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.
Can coordinates have letters?
Coordinates are a set of numbers or numbers and letters together that show you a position on a map. Coordinates are written in parentheses and separated by a comma: (H, 4).
How many digits is a grid reference?
A grid reference shows a particular location on a map using 4 digits or 6 digits. The grid reference depends on eastings and northings. Eastings are eastward measured distances. They are similar to the x-axis on a graph.
What is 4 figure grid reference?
A 4-figure grid reference contains 4 numbers. For example, you might be given the number 3422. The first two numbers are called the easting, which is the number you would look for at the bottom of the map. Your grandfather gives you the 4-figure grid reference 1331.
What is 4 digit grid reference?
Four figure grid references locate a grid square (usually 1 km square) on a map. The four figure grid reference is always given for the bottom left hand corner of the square (the South West corner) and you always write the Eastings before the Northings [Hint: Along the corridor and up the stairs].
What is an alphabet grid?
This grid with 26 spaces is designed for who are beginning to write the alphabet. The boxes help students to visualize how far along they are in the process and identify whether they skipped any letters (if there are blank boxes left at the end of the exercise).
What is a Letter number grid?
An alphanumeric grid (also known as atlas grid) is a simple coordinate system on a grid in which each cell is identified by a combination of a letter and a number. Some kinds of geocode also use letters and numbers, typically several of each in order to specify many more locations over much larger regions.
How do you write a four-figure grid reference?
Write this two-figure number down. Then use the northing to go up the stairs until you find the same corner. Put this two‑figure number after your first one and you now have the four-figure grid reference, which looks like the example in diagram D: 6233.
What does a grid reference tell you?
A grid reference tells you where something is on a map. The 1st letter or number tells you how far across the map something is. The 2nd letter or number tells you how far up the map something is.
How do you reference a grid in an A4 paper?
Grid References. The grid references start from the top left of the sheet, with letters running vertically from the top down and numbers running horizontally from left to right. On an A4 sheet the grids only need to be drawn on the top and left hand side. The letters I and O are not used – because they could be confused with 1 and 0.
What are the first letters of the National Grid?
There are four main first letters: ‘S’, ‘T’, ‘N’ and ‘H’ covering Great Britain, plus an ‘O’ square covering a tiny part of North Yorkshire that is usually below tide. A unique National Grid reference should have this two-letter descriptor followed by the grid reference numbers within that square.
