Question

how to find six grid reference in the Contour map​

Answer 1

Four-figure grid references When giving a four-figure grid reference, you should always give the easting’s number first and the northings number second, very much like when giving the reading of a graph in school, where you give the x coordinate first followed by the y. An easy way to remember this is that to get the first number, you go along the corridor (horizontal, x axis, easting’s) 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’. The numbered squares on the diagram above have the following four-figure grid references: 1 = 18 45 2 = 19 45 3 = 18 44 4 = 19 44

Answer 2

By taking the number of easting and northing grids we can locate things on the map. In six-figure grid square method after getting the four figures again, easting and northings are divided into ten equal parts and both easting and northing subdivision numbers are taken out.
