Philip's Navigator[registered] Britain shows speed-camera locations, with their speed limits, and provides over 3,000 road names as well as numbers. It also includes a massive selection of 72 indexed town-centre maps, plus airport and port maps, detailed approach maps, London main roads maps, detailed route-planning maps, a distance table, and a 43,000-name index which includes places of interest. The main road maps are at 1.5 miles to 1 inch (3 miles to 1 inch in the Scottish Highlands) and are extra clear and detailed, showing even the smallest roads and lanes that are omitted from other atlases.Every roundabout, junction and slip-road is shown in detail on main roads and motorways. In country areas, thousands of individual houses and farms are marked, along with footpaths and tracks. The alpha-numeric grid is based on the National Grid, so that the atlas can be used with GPS systems, and the grid squares have been made smaller for this edition, making it easier to find locations when using the index. Thousands of tourist attractions and places of interest are shown on the maps, including national parks, nature reserves, houses and gardens, beaches, marinas, canals, county showgrounds, camping and caravan sites, shopping villages, tramways, World Heritage Sites, long-distance footpaths, sporting venues, park and rides, and ferries. Philip's Navigator[registered] Britain is widely used by professional drivers and the emergency services, including national police training, and is recommended in the motoring press and national newspapers.
