Geometry includes making maps {cartography}.
Symbols {notation, map}, such as colors, contours, and dots, describe maps.
Drawing maps can use projective metric geometry {projection, map} to put actual surface onto map.
Map relates map distances to actual distances {scale, map}. Scales use units or ratios. For example, rulers can be one meter long, marked in centimeter units.
Maps {topographic map, cartography}| can have both natural features and human-made features.
