NORTHINGS AND EASTINGS

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

Gives us a general position on the map (i.e. the whole box)
Use the #’s of the two lines that cross in the SW corner (bottom left) of the box
Easting # is written first
Northing # is written second

Each square can be further divided into 10 equal parts
This gives a more specific location (i.e. a point within the box)
