Orientating your map allows you to quickly compare features on the map with those visible on the ground by holding the map at the same rotation as the ground. Whilst often it is possible to orientate your map by direct comparison with the landscape alone, on unfamiliar ground or when features are ambiguous it is helpful to use the compass instead.

First place the compass on the map, aligning the base plate with the gridlines so that the end of the baseplate points north. In theory you may place the compass anywhere on the map but it’s handy to be able to see your immediate area.

Next, rotate the compass housing so that it is also aligned with the gridlines. The markers on the base plate and the housing should be aligned. North on the compass housing should be pointing up the baseplate and north along the gridlines.

Now, with the baseplate fixed relative to the map, rotate the map and the compass until the north end of the pointer is aligned with the rest of the compass. The north pointer of the needle should fit between the markers on the housing.

Your map is now aligned. Features should be the same direction on the map as they appear to you on the landscape. If possible it is wise to confirm this using the landscape but where features are unfamiliar or ambigous it is usually wise to trust the compass.#
