Street maps or road maps are maps that primarily displays streets and transport links instead of natural geographical information. They are types of navigational maps that commonly include political boundaries and labels, making them types of political maps as well. In addition to streets and boundaries, a street map usually includes points of interest (POIs) such as prominent buildings or businesses, tourism sites, parks or recreational facilities, airports and train stations, as well as hotels and restaurants. A street map may also show non-automotive transit routes, though some times these are found only on transit maps. Collections of road or street maps are usually called street atlas or road atlas.
