That looks perfect. In practice, you'll probably find it difficult to map a bog as a whole, rather it's the big empty brown bit that you'll generally end up mapping. > I think peat is the same as turf, used in domestic fires? It certainly is. In traditional use, cuboid sections of peat/turf would be extracted from the bog and left in the open air to dry. These were of a shape and size useful for a domestic fire. On the mass-market these days you generally get peat briquettes, which are made of milled peat, extracted mechanically from the exposed surface of the bog. This is then compressed into briquettes. Ireland created a nationalised industry to exploit the bogs shortly after independence. In a state striving for independence, turf filled the gap caused by the fact that we had essentially no native coal.
