GRID REFERENCES NORTHINGS AND EASTINGS
NORTHINGS AND EASTINGS þ NOT THE SAME AS LATITUDE AND LONGITUDE þ Used to help you locate a specific spot on a flat map þ Uses a grid of lines crossing at right angles þOn the map the LINES are numbered not the spaces
NORTHINGS AND EASTINGS þ EASTINGS: þVertical lines on the grid system þ# from west to east on the map (left to right) þ#’s increase towards the east
NORTHINGS AND EASTINGS þ NORTHINGS: þHorizontal lines on the grid system þ# from south to north on the map (bottom to top) þ#’s increase from south to north
