T-square grid Each lettered square’s bottom left corner begins at 0 and progresses to 100 in each direction. Determine the letter for the 100,000-meter grid square in which the point is located.Let’s create a grid reference for Lugnaquillia using the procedures below. This allows you to provide a six-figure grid reference. If you want to be precise with your grid reference, mentally divide each side of the grid reference box into ten. This is especially critical in an emergency situation. When getting a grid reference, always read from left to right along the bottom or top of the map, then bottom to top along the side of the map.

That may be because you sprained your ankle while out and about and need assistance, or because you discovered an intriguing antiquity and want to share it with a buddy. Grids on maps have a different purpose they aid in determining where you are on a map. The scale of our Discovery series map is shown below. If you have a map on a square meter of paper with a scale of 1:50,000 and another map on the same size paper with a scale of 1:25,000, the first map will cover four times the area covered by the second map.Įvery map will include a scale, not only the number, say, 1:50,000, but also a representation of that scale. The smaller the region covered by a map, the larger the scale. Scales let us calculate the distance to our destination and, as a result, how long it will take us to get there. At the bottom, the horizontal line is the X axis, while the vertical line is the Y axis. The horizontal line is said first, followed by the vertical line.

Every ordnance survey map in the world has a six-figure grid reference and a four-figure grid reference for each location. In grid references, and we’ve learned about six figure grid references and four figure grid references. The distinction between grid references and coordinates is that coordinates are where lines intersect, whereas grid references are in between lines. Grid references are located between the lines, giving the appearance of a math square with numbers.

They always travel in a straight path and either go up and down or across the road. There are two lines that appear on all maps: the vertical and horizontal lines.
