How do you do an 8 figure grid reference?
How do you do an 8 figure grid reference?
In order to obtain an 8 figure grid reference, you need to carry out the exact same procedure to obtain a 6 figure grid reference, dividing your grid square into tenths, but then further sub-divide the 6 figure tenth in which your location lies into further tenths (the 8 figure tenths).
How accurate is a 8 figure grid reference?
With an 8-figure reference, the last figure in each half of the reference (the easting and the northing) again subdivides this tenth into 10 parts, so that the accuracy is then to within 10 metres, and this is why you need a larger scale than 1:50,000 to make good use of it.
What is a figure grid reference?
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.
How do you read grid references?
An easy way to remember this is that to get the first number, you go along the corridor (horizontal, x axis, eastings) and then up the stairs (vertical, y axis, northings). For example, the number 2 in the diagram below is square 19 across and square 45 up and therefore, the four-figure grid reference is ‘1945’.
How accurate is a 10 figure grid reference?
Any of the 100 squares in the superimposed 10×10 grid can be accurately described using a digit from 0 to 9 (with 0 0 being the bottom left square and 9 9 being the top right square). Grid references comprising larger numbers for greater precision could be determined using large-scale maps and an accurate Romer.
What’s a 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. The intersection of these grid lines is the bottom left corner of the square where the surprise is.
How do you find a six figure grid reference?
After writing three digits of eastings, write two digit of the last northings and then from the bottom of the last northing, measure the distance to the object with a ruler in mm. Then divide that resultant distance by 2. This will give you the sixth number of the grid.
What does the six figure grid reference 198823 tell you?
What does the six-figure grid reference 198823 tell you? It gives you an exact point in grid square 1988 that is 2/10s up and 3/10s along. It gives you an exact point in grid square 1982 that is 8/10s across and 3/10s up.
