Your map collection
All leaders should maintain a collection of maps, from small-scale touring maps, through selected 1:250 000 topographic maps, to the accumulated maps acquired for various trips. Your collection is not only for use in the bush, but also as a reference for trip planning and preparation.
Most government mapping agencies produce index sheets setting out the maps available at different scales. Usually free and updated once or twice a year, these key index sheets are invaluable not only as a guide to what is available but also for the description of the required map.
