Happy with the printer I found last week, so print 2/100 of the "overland track in blue" is ready! A2 giclee print on 310 gsm platine rag.

It's probably really only going to be a 50 print run - odd numbers are a slightly different shade of blues ;)

Available here: https://bluethumb.com.au/adam-steer/Artwork/topography-of-the-overland-track-in-blue-0

...or get in touch - although bluethumb offer better shipping and insurance networks than I can.

Was just thinking about the shape of the east coast (the curved crest shapes) and hurricanes, and whaddyaknow, there seems to be a link! I'm sure it's not as simple as that, though, can anyone out there recommend further reading on the topic?

J'aurais bien voulu savoir comment basculer les posts de mon ancienne instance vers celle-ci, mais tant pis! Je vais refaire un gros thread pour montrer tout ce que je vends sur ma boutique en ligne.

Voici ma série d'affiches sur les cartes topographiques des départements d'Auvergne.
Ici c'est le département du Puy-de-Dôme

Now that I have a new home on solarsystem.social, here's a new #introduction!

I am a #planetary scientist working at the Institut de Physique du Globe de Paris (#IPGP) in France. My research uses the #gravity field, #topography, and #MagneticField of the planets to decipher their internal structure and geologic evolution. My favorite terrestrial body is the #Moon, but I also work with #Mercury, #Venus, and #Mars. Soon I will need to learn about #Psyche and the icy satellites of #Jupiter!

Steven Wright used to joke that his map was printed at 1:1…but I think we may have come closest to that reality.

Q: What do you get when you give middle school kids a thousand topographic maps, a key, and a gymnasium?

A: The entire state mapped at 1:24,000!
