An Evolution of Cartography is an online workshop offered by the Guardian as part of a series they’re calling masterclasses. “In this insightful masterclass with experts from Ordnance Survey, you will discover how maps, and our relationship to them, have evolved over time. You will learn how the way that a map is designed can influence the way in which it is interpreted, and why this means that even the most authoritative map may not be as objective as we think.” The three-hour course, taught by the OS’s Paul Naylor and Jess Baker, focuses on data visualizations and map techniques. It takes place on Thursday, 17 March 2022 and costs £89 plus booking fee. [WMS]
