Great talk by @ProjectionWizz at #ICC2023 who presented on the maths of map projections in a way that even I mostly understood. Quote of day too: "When I tell you the projection is square but you're seeing a rectangle it's because of local projector distortion. It's a square."
Level up 🎉 I reached @localguides level 5 by helping others explore on Google Maps. #localguides
Ahead of Her Majesty The Queen’s State Funeral, a new photograph has been released. The photo was taken to mark Her Majesty’s Platinum Jubilee - the first British Monarch to reach this milestone. Tomorrow, millions will come together to commemorate her remarkable life.
A map I wasn't expecting to make today, but my own simple way to honour the life of Her Majesty Queen Elizabeth II. carto.maps.arcgis.com/apps/webappvie… #QueenElizabeth
Can one export .wld file using AutoCad or similar software? @JSDBroughton you might know?
My brilliant daughters.
This is my go-to example when talking about how 2D map projections can impact the perception of location, size, distance, and direction (compared to 3D global reality).
At the Geodienst we believe one size fits all. Oh wait. 😉 #mapping #projection #dataviz

Final attempt to map #Ukraine refugee crisis more empathetically through permeable borders ??? No arrows No symbol units Indicative quantity Relative densities Random placement More organic Greater spread = more Colour = Ukranian diaspora Outward flow & dispersal #cartography

It's as good a time as any to review radical cartographer Bill Bunge's 1988 Nuclear War Atlas. The book is hard to find (check your local library) but you can get the gist from this 1982 poster on @JeremyCrampton's blog: opengeography.wordpress.com/2018/08/07/bil…
Exceptional work 👏👏👏 🇺🇦
A New Map Designed for 1870 by Paul Hadol in the wake of the Crimean War
In 50 days the print edition of my @EsriPress book #ThematicMapping is published. It explores alternative ways to make maps, how to be more ethical and truthful making them, and more discerning when reading them. Pre-order from online retailers. Go on...you know it makes sense.
A fabric womb, dated 1760. In 1759 king Louis XV commissioned pioneering midwife Angélique du Coudray to teach midwifery to rural women to reduce infant mortality. Between 1760 to 1783, she traveled rural France and it is estimated that she trained 4000 students during that time.
