It is a method used to identify a specific area on a map.
The map is overlaid with a grid or square boxes in columns and rows.
Each row and column have a number.
By giving a row and column number any particular box or part of the grid can be identified.
It should be noted that in some countries the column number is given first followed by the row number, in other countries, this is reversed.
Be sure you are aware of which convention is being used.
a 4 figure grid refrence of old harry rock
What is durdle door in 6 grid refrence?
to be able to draw 4 figure grid reference
expkain how four figure grid references are used to find places on map
The disadvantages of four figure grid references are 1 grid reference is 10 2 is 10 3 is 30 and 4 goes to 400..
The difference is that the 4 figure grid map is used for roughly the place that is located in the map while a 6 figure grid is used to find the exact location on the map. So when there's a need to find the exact location use the 6 figure grid instead of the 4 figure grid map.(:
To use a toposheet you first need to find the place. Then see the Northings and the distance from the left northing. after that see the eastings and similarly the distance.The eastings are written first and then the northings.this is callled the six-figure grid refrence.
A 6-figure grid reference provides a more precise location than a 4-figure grid reference by pinpointing a specific area within a grid square. While a 4-figure reference identifies a general location within a 1 km by 1 km square, a 6-figure reference narrows it down to a 100 m by 100 m area. This increased accuracy is especially useful in navigation, mapping, and emergency situations where exact locations are critical.

Because it is much more accurate (long distances) Larger the figures the greater the accuracy- (very accurate)
say the grid reference was 038441 the four grid referecne would be 0344 which is taking of the 3rd and last number
A six figure grid reference is a more detailed type of grid reference. Basically you divide the squares into 100 smaller squares then write a three figure easting then a three figure northing all you really have to do is take away the decimal point
