We all know how important navigation can be, especially when out in the country and in poor weather. Being able to navigate well using a map, compass, gps device* or smartphone* with decent maps can add to our enjoyment and safety when out on a walk.
There are lots of publications and sources of advice on map reading and navigation available in bookshops and on the web:
Ordnance Survey guide to map reading - suitable for beginners but also has some helpful reminders for the more experienced.
Ramblers' website page on map reading - an introduction to maps
*Note that any advice about gps or smartphones in the context of navigation will always warn against relying on battery operated devices and on devices that require a good phone signal to access locations and mapping. However, many apps are available that have built-in mapping, often versions of the OS Landranger or Explorer series; these need a GPS signal, of course, but do not need a phone signal to be effective. Remember that batteries become less effective and have a shorter life when cold.
