A map is a symbolic representation of selected characteristics of a
place, usually drawn on a flat surface. Maps present information about
the world in a simple, visual way. They teach about the world by showing
sizes and shapes of countries, locations of features, and distances
between places. Maps can show distributions of things over Earth, such
as settlement patterns. They can show exact locations of houses and
streets in a city neighborhood.
Mapmakers, called cartographers, create maps for many different
purposes. Vacationers use road maps to plot routes for their trips.
Meteorologists—scientists who study weather—use weather maps to prepare
forecasts. City planners decide where to put hospitals and parks with
the help of maps that show land features and how the land is currently
being used. Some common features of maps include scale, symbols, and
grids.
