Article Correctness Is Author's Responsibility: MapLab: Trump’s ‘Mutilated’ Storm Map

Welcome to the latest edition of MapLab. Sign up to receive this newsletter in your inbox here.

Mark Monmonier has devoted his career to dissecting the ways that maps are less than truthful. The author of How to Lie With Maps and a distinguished professor of geography at Syracuse University, Monmonier has written about countless examples of manipulative cartography.

But the doctored chart of Hurricane Dorian’s path that President Trump displayed at a press conference last week stands out as the most flagrant example of deceptive cartography that Monmonier can think of.

The map from the National Oceanic and Atmospheric Administration showed the storm’s predicted path into Florida and up the southeastern seaboard. Notably, the official chart didn’t include any part of Alabama—at that point, no storm forecasts showed that the state was in danger. But an extra appendage drawn in thick black ink suggested otherwise, a cartographic mutilation that kicked off an ongoing administrative/media drama now known as #SharpieGate.

For CityLab, I spoke to Monmonier to hear how this incident fits in to the broader history of manipulative mapping, and why he believes maps are such unusually potent sources of misinformation.

“Usually, attempts to falsify tend to happen before maps are published, and don’t try to contradict established scientific facts,” he told me. “It’s probably indicative of the special respect for maps, that [Trump] thought that his alteration of this map would take precedence over the facts that were already printed on it.”

Where there were dragons, he saw his childhood

The latest installment of CityLab’s Maps That Make Us series tells a powerful tale of how a well-known Renaissance map gave a young boy sanctuary amid the violence and turmoil of 1980s Northern Ireland.

The Carta Marina in all its otherworldly majesty. (Word Digital Library)

Darran Anderson, a longtime contributor to CityLab on all things maps and cities, describes how the clash of fantasy and reality in the 16th-century Carta Marina changed the way he saw his childhood neighborhood in Derry:

I began to draw my own maps. I focused on charting my neighborhood: a run-down working-class Catholic and Irish Republican area, made up of terraced houses that had once housed Victorian shipbuilders. I drew wind-roses, compass points, cherubs blowing winds. I recorded the hiding places only my fellow street urchins and I knew of, beyond the sight of adults. I mapped places where suspected treasure lay, like a small orchard in an alleyway, and places where perils beckoned, like a Brutalist block of flats, the glass-strewn alleyways, and the British Army watchtower that loomed over us in Rosemount. I even created “Here be dragons”-esque creatures in the forbidden Glen, a wild wasteland area that we were continually warned away from and thus seemed to us to be full of adventures. Everywhere peripheral is a center for someone.
