    18. 18. Eastings, northings and area references This diagram uses a different type of grid system. It is made up of numerals located on grid lines.
    19. 19. Eastings, northings and area references The numbers that refer to the vertical grid lines are called eastings.
    20. 20. Eastings, northings and area references They increase in value as you move across in an easterly direction.
    21. 21. Eastings, northings and area references The numbers that refer to the horizontal grid lines are called northings. They increase in value as you move up in a northerly direction.
    22. 22. Eastings, northings and area references The two eastings numbers are joined with the two northings numbers to make a four-figure area reference.
    23. 23. Eastings, northings and area references For example, a % symbol is located at eastings 46 and northings 22, so its area reference is 4622.
    24. 24. Eastings, northings and area references Which symbol appears at these area references? 4124 Answer – 4425 Answer – 4323 Answer – 4120 Answer –
    25. 25. Grid references Grid references locate places on a map more accurately than area references. A grid reference is a six figure number, made up of a three-figure eastings reading and a three-figure northings reading. A grid reference is found by mentally subdividing each grid square into tenths. The third figure in each eastings and northings reading is found by estimating how many tenths across or up the exact location is.
    26. 26. Grid references What is the grid reference for the Post Office? Answer – 283579
    27. 27. Grid references Name the feature at 280570. Answer – An island
    28. 28. Grid references Name the feature at 258576. Answer – The river mouth

    40. 40. Grid coordinates – latitude and longitude The exact location of any place on Earth is given by its geographic coordinates. You can find examples in the index of your atlas. Measurements for latitude and longitude are given in degrees (and minutes). Latitude is stated first, then longitude. Sydney’s geographic coordinates are: 33.52S 151.10E
    41. 41. Grid coordinates – latitude and longitude Tokyo’s geographic coordinates are: 35.40N 139.45E Tokyo

    43. 43. Grid coordinates – latitude and longitude Cairo’s geographic coordinates are: 30.03N 31.15E Cairo
    44. 44. Grid coordinates – latitude and longitude Cape Town’s geographic coordinates are: 33.56S 18.28E Cape Town
    45. 45. Grid coordinates – latitude and longitude Geographic coordinates and alphanumeric references are used in the index of an atlas. One atlas gives Sydney’s reference as Map 50 J12 33.52S 151.10E. To locate a place in your atlas, check: • the map number • the grid • geographic coordinates – latitude first, then longitude.
