Navigation and Mapping Techniques
Mental Maps
The Burarra people can navigate without using maps. Instead, they
use their memory of familiar landmarks and natural features.
Navigating at Night
At night when it is too dark to see landmarks the Burarra
people use the stars to navigate.
The positions of the stars in the
night sky change throughout the night and the year. Like the Sun,
stars appear to move across the sky from east to west each night.
This is caused by the movement of the Earth spinning on its
axis. The Earth also orbits the Sun. This causes a slow precession
across the sky, where from night to night the stars appear to start
a little further west each night. This slow movement is what
makes the wet and dry season (or summer and winter) skies totally
different.
The Burarra
people recognise the pattern of
stars
at different times, and use these to guide them. A particular
star is followed to make sure they are traveling in the right
direction.
The best time of year to use the stars for navigation is during
the dry season when there are no clouds in the sky. The dry season
is also a good time to travel in a boat at night because the seas
are calm and the breeze is gentle.
