[[Road map]]s are perhaps the most widely used maps today. They are a subset of navigational maps, which also include [[aeronautical chart|aeronautical]] and [[nautical chart]]s, railroad network maps, and hiking and bicycling maps. In terms of quantity, the largest number of drawn map sheets is probably made up by local surveys, carried out by [[municipality|municipalities]], utilities, tax assessors, emergency services providers, and other local agencies.  Many national surveying projects have been carried out by the military, such as the [[United Kingdom|British]] [[Ordnance Survey]]: a civilian government agency, internationally renowned for its comprehensively detailed work.

The location information showed by maps may include [[contour line]]s, indicating constant values of [[elevation]], temperature, rainfall, etc.
