Information can be represented in a series of map overlays. For example, plotting sheep paddocks or runs over a topographic
base map may reveal that sheep grazing did not extend above a certain altitude; or plotting mining site relics over a geological
map could indicate the routes connecting mine sites, and how the distribution of geological formations and the search for
payable gold interacted to shape the landscape. Alternatively, the information could be plotted on a series of map overlays to
show successive or sequential uses and the resulting changes in the landscape over time. For example, a forest area could have
been cleared and grazed, then abandoned; recolonised by forest, selectively logged, and finally reserved for conservation. These
map overlays can be stored in a Geographic Information System as computerised data to which other variables can be added for
further analysis. They should also be held as hard copy maps.
