A map is a two-dimensional representation of a three-dimensional surface. It uses a coordinate system to show locations and directions, and it shows the length and width of features that are large enough to be depicted at the scale at which the map has been drawn. Declination is the difference in degrees between compass north and true north. A bearing is the compass direction along a line from one point to another. Finally, map symbols show vegetation cover, types of roads, and so on, providing details about an area.
