Welcome to the website of the California Map Society. We invite you to take a tour, bookmark our site and come back for more. You'll find new and unusual sights with every visit.
Here you’ll encounter stories behind historic maps, ways that modern topographic maps are made, techniques for making maps and even making a geographic information system (GIS)... yourself, how to start your own map collection and much more. We at CMS especially enjoy maps of California and by Californians—which covers a lot of territory—but you’ll find much more than California inside.
