“The Monsters of Maps,” a 10-minute video by Richard Tilney-Bassett, explores the late-19th- and early-20th-century phenomenon of “serio-comic” or caricature maps, which are no stranger to us here. In the video Richard wonders what a modern-day caricature map would look like; I’d point him to the work of Andy Davey (see here and here).

CBC News explores how the production team for the First World War epic 1917 consulted McMaster University’s collection of trench maps and aerial photography to produce an authentic replica of a situation map for the movie. The map they used, incidentally, is this one, a situation map showing British and German troop positions around Monchy-le-Preux on 24 April 1917:

During World War I, Australian troops staying at nearby Hurdcott Camp carved a gigantic map of Australia into a Wiltshire hillside. Chalk gravel was used to fill shallow trenches to create an outline map some 150 feet wide with 18-foot-tall letters. Since then, despite a restoration in the 1950s and its designation as a Scheduled Ancient Monument, the map has faded, but for the past four years the Map of Australia Trust has been working on restoring the map. It was finished in time for Armistice Day. More from BBC News (video) and Historic England. [Jonathan Potter]

Forgotten Wrecks of the First World War is an interactive map of more than 1,000 wartime wrecks along England’s south coast. Like much of the material and personal history of that war, the wreck sites—”which include merchant and naval ships, passenger, troop and hospital ships, ports, wharfs, buildings and foreshore hulks”—are degrading; this is a project designed both to raise awareness and preserve information. Selecting a wreck site brings up a wealth of detail about the ship, its current state, and the circumstances of its loss. More at the project page and from BBC News. The map itself is a basic Mapbox affair, with a layer that only looks vintage (there are motorways). [Kenneth Field]

Today marks the 100th anniversary of the Halifax Explosion, which took place when a French cargo ship laden with explosives collided with another ship in Halifax Harbour. The resulting blast killed around 2,000 people and devastated the city of Halifax, Nova Scotia; it was the largest artificial explosion of the pre-nuclear age.

Maps Mania points to a couple of interactive maps of the explosion produced by Canadian news media. CBC News’s A City Destroyed: Experience the Halifax Explosion 100 Years Later is a bit over-produced, with 360-degree video and a non-clickable map that immediately segues into a 3D environment with limited interactivity. (It also pegs one of my CPU cores.) Global News’s interactive map is more modest in scope: developed by Patrick Cain, it’s a Google Maps mashup that points to the known addresses of those killed by the explosion. (Casualties in Dartmouth, across the harbour from Halifax, aren’t mapped because the data weren’t available.)

Today marks the 100th anniversary of the Sykes-Picot Agreement, a secret pact among the Triple Entente to partition the Ottoman Empire into their respective spheres of influence. Above, the map delineating those spheres of influence, signed by diplomats Mark Sykes and François Georges-Picot eight days earlier. [NLS Maps]
