Our relationships with maps changed very dramatically in many different ways in the 20th century. One of the important changes is not only that maps became more widespread and familiar, but how that affected our relationships with them. The examples in the exhibition richly illustrate many of these changes, but one trend I would like to focus on here is the recognition that the power of maps became increasingly hidden as they became more accurate and realistic.
Perhaps the most iconic example in the exhibition is the Van Sant first map of the earth from space that appeared in Scientific American in 1990. This immense technological achievement has often been described as âshowing the real world as it appears from spaceâ (www.tomvansant.com). But it was also a huge artistic achievement. And it both symbolised and contributed to the decline of the traditional map maker. This is a kind of photograph, and photographs donât lie.
But think about this claim for just a moment as you look at it: no clouds; daylight around the whole planet; the Atlantic ice at its summer limit. This image is, as the article recognises, âequal parts software and artistic judgementâ. Is this âthe real world as it appears from spaceâ? Or is it an interpretation, much like any other map? There is no doubt that publication of this image marked a massive milestone for maps in the 20th century. It seems to be so very different from imperial propaganda maps for example. And yet, as the exhibition explores, maps are by nature unreliable witnesses â misleading their readers as well as informing them.
The label âcritical cartographyâ was coined in the 20th century to describe a way of looking at maps. Critical geographers questioned their hidden assumptions and compromises, and revealed their inherent unreliability and partial truth. They did so not to invalidate maps, but to understand their power more thoroughly. This approach shared much with âcriticalâ developments in the 20th century in other areas of life, such as epic theatre, literary theory, cultural geography, and educational policy.
The exhibition explores the profound incursion of maps into everyday life in the 20th century. At the same time, the profound social, political and cultural changes often hidden in everyday life can also be seen in the development of maps and especially in understanding our relationship to them.
