Historical, a map is worth a thousand pages : ex: hurricane tracks in 1995, one-dimensional data. Points: ex: locations at which the storms became strong enough to become a hurricane. Areas (polygons: regions political, climatic, choropleth map displays regions using colors, lines of different weight, etc qualitative. Isoline map divide the area into regions based on values of some data quantitative: features. Scale a tool or rule that allows us to convert measurements of the map into real world equivalence: graphic scale line or bar broken into different steps. If the size of the map changes, the ratio stays the same: representative fraction can be written as a true fraction, or ration form, or verbally. If the size of the map changes, the scape becomes inaccurate. Key/legend guide that allows us to interpret the meaning of the map.
