Us Map are also distinct for the global knowledge required to construct them. A meaningful
map of the worldcould not be constructed before the European
Renaissance because less than half of the earth’s coastlines, let alone its interior regions, were known to any culture. New knowledge of the earth’s surface has been accumulating ever since and continues to this day.
Maps of the world generally focus either on political features or on physical features. Political maps emphasize territorial boundaries and human settlement.
Physical maps show geographic features such as
mountains,
soil type or
land use.
Geological maps show not only the surface, but
characteristics of the underlying rock,
fault lines, and subsurface structures.
Choropleth maps use color hue and intensity to contrast
differences between regions, such as demographic or economic statistics.
