What type of features in cartography are generally italicized?

In cartography, certain conventions are employed to help distinguish different types of features on a map for improved readability and comprehension. Water features, such as rivers, lakes, and oceans, are typically italicized in map design. This typographic choice helps to visually set these features apart from other elements on the map, allowing viewers to easily identify aquatic features among the various geographic components presented.

This convention supports the visual hierarchy of information, making it clearer for users to interpret the map. By using italics for water features, cartographers utilize an established standard that enhances the overall user experience when engaging with maps.
