The only detailed colour atlas that gives comprehensive coverage of the entire county with many features named in both English and Welsh - no other atlas names every street in Ceredigion and an area of Gwynedd south of a line from Porthmadog to Bala (but not including the Lleyn peninsula). The maps are at a scale of 2.66 inches to 1 mile with less populated areas mapped at 1.3 inches to 1 mile and feature every named road, street and lane, with time-saving through-routes highlighted in urban areas. Also shown are postcode boundaries, school locations, emergency services, hospitals, police stations, car parks and rail and bus station locations. There is a comprehensive index of street names and postcodes, plus schools, industrial estates, hospitals, sports centres, etc. all highlighted in red.
