Write this number after the first two digits.

Estimate or measure how many tenths across the grid square your symbol lies.You will see that the symbol sheet has 1:50,000 written on the top. Task 3 - You will now complete this OS map symbols sheet using the link beneath to help you to draw and complete the symbols as necessary. First, find the four-figure grid reference but leave a space after the first two digits. Here is an 18 minute video that explains a little more about the company (not obligatory to watch).The distance between one grid line and the next is divided into tenths. In this case you can imagine that each grid is divided into 100 tiny squares. Sometimes it is necessary to be even more accurate. In this case, the tourist information office is in grid square 4733. Look at the number of this grid line and add it to the two-digit number you already have. Move north until you get to the bottom-left corner of the square you want.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.

When you give a grid reference, always give the easting first: ' Along the corridor and up the stairs '.įour-figure grid references can be used to pinpoint a location to within a square.The horizontal lines are called northings as the numbers increase in an northerly direction. They are numbered - the numbers increase to the east. A grid of squares helps the map-reader to locate a place.
