The Maps and Cartography Portal

A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geographic elements, they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension.

Maps of geographic territory have a very long tradition and have existed from ancient times. The word "map" comes from the medieval Latin: Mappa mundi, wherein mappa meant 'napkin' or 'cloth' and mundi 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. (Full article...)

Cartography (/kɑːrˈtɒɡrəfi/; from Ancient Greek: χάρτης chartēs, 'papyrus, sheet of paper, map'; and γράφειν graphein, 'write') is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively.

The California Field Atlas is a 2017 book written and illustrated by Obi Kaufmann. It was published by Heyday Books, a Berkeley-based nonprofit small press. Through passages of nature writing and hundreds of watercolor paintings, the book details California's ecology and geography. Kaufmann, an artist and outdoorsman, was born in California and currently resides in Oakland. He prepared the book over the course of a year, drawing from a lifetime of experience hiking thousands of miles of California wilderness. With the California Field Atlas, he intended to foster geological literacy and conservation of the state's natural environment.

The book contains ten chapters spanning more than 500 pages in total. The first eight chapters examine California's ecological system, the ninth chapter is an overview of nature throughout the state's 58 counties, and the final chapter covers the topic of rewilding. Rather than focusing on already-famous natural landmarks such as Yosemite, Kaufmann sought to present a comprehensive overview of the state that included detailed surveys of lesser-known regions.

Antarctica, the continent surrounding the Earth's South Pole, is the coldest place on earth and is almost entirely covered by ice. Antarctica was discovered in late January 1820. Too cold and dry to support virtually any vascular plants, Antarctica's flora presently consists of around 250 lichens, 100 mosses, 25-30 liverworts, and around 700 terrestrial and aquatic algal species.
