How 20th-Century Women Put the 'Art' in Cartography

The Women Cartographers Who Mapped Art and Science in the 20th Century - CityLab

See also: In , the state of Georgia banned a book of patriotic songs she had illustrated with images of black and white children. By combining the knowledge of Africa , the Indian Ocean , Europe , and the Far East which he learned through contemporary accounts from Arab merchants and explorers with the information he inherited from the classical geographers, he was able to write detailed descriptions of a multitude of countries. In difficult cases where there is not enough space to place the label near the feature to form an unambiguous association, a leader line can connect the label to the feature.

Good Luck Well, I hope that assortment of tips and problems has been useful. This was an equal-area, heart-shaped world map projection generally called a cordiform projection which was used in the 16th and 17th centuries. General cartography involves those maps that are constructed for a general audience and thus contain a variety of features. The cartographer is thus constantly making judgements about what to include, what to leave out and what to show in a slightly incorrect place.

About 1, of these are known to have survived: In the 16 th century, Mercator developed a world map mainly used for ocean navigation, and this projection is still used to this day for a number of purposes. Datasets often contain many duplicate values; when quantiles are calculated properly, a single value could span several classes.

Beck's London Underground map is an iconic example.


This is an adaptation of a talk I gave at the OpenVis Conference in Boston, expanded in a few spots and abbreviated in others. One at a time, place the peels on an overhead projector and discuss the shapes as a whole class. Have them choose an audience: For example, using an italicized, dark blue font for a water label can suggest waves.

Blindfolded Cartography

Geography and Ethnography: Cartography in the Prehistoric Period in the Old World: Again, it's good to be explicit. This article only references primary sources.

Text, too, can be an unknown part of map data—one that can ruin otherwise beautiful layouts. This also eliminated the need for engraving, which further speeded up map production.

The same property limits its value as a general-purpose world map because regions are shown as increasingly larger than they actually are the further from the equator they are.

Most maps label features so that the map reader can know features' names. On one side is code that won't break if a null value is thrown at it.

In the maps below, an unusual attention to graphic quality shows—even in those that helped to chart new scientific territory. How do we accomplish good human design when there's simply too much data for a human to see? What do you observe about the lines of longitude in each of these map projections?

In some cases the correct name is not clear.
