Pointing estimates for all locations (ALL) and each of the 10 data collection locations overlaid onto a magnetic compass, with adjacent road orientation and mean pointing direction indicated (using circular statistics).

<p>Note that this figure is aligned with magnetic north, whereas <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0135803#pone.0135803.g001" target="_blank">Fig 1</a> is aligned with true north; relating the two figures must thus consider declination.
