There should be some indication of which direction North is on the map. Many maps have grid
lines criss-crossing the map. Normally these run North-South and East West. However this is not always the case. There is
a 1:250,000 scale map of Jasper National Park that does not follow this norm.
Grid ReferencesGrid lines are drawn on our 1:50,000 maps at 1 km intervals. A grid reference locates a position to
the nearest 100 meters. However any 6 digit grid reference will also occur at points 100 km north, south, east and west of
this point. So for a more precise reference always quote the map number or the full grid reference using the other numbers
on the side of the map close to the corners.
| The first 3 numbers are the west-east reference and the last 3 are the south-north reference, e.g.:
- The grid reference of point x is 574138
- Point x is 4/10ths of the way from the 57 line to the 58 line
- Point x is 8/10ths of the way from the 13 line to the 14 line
