1. GRID REFERENCES NORTHINGS AND EASTINGS

2.  NOT THE SAME AS LATITUDE AND LONGITUDE  Used to help you locate a specific spot on a flat map  Uses a grid of lines crossing at right angles  On the map the LINES are numbered not the spaces

3. NORTHINGS AND EASTINGS  EASTINGS:  Vertical lines on the grid system  # from west to east on the map (left to right)  #’s increase towards the east

4. NORTHINGS AND EASTINGS  NORTHINGS:  Horizontal lines on the grid system  # from south to north on the map (bottom to top)  #’s increase from south to north
