🔔 NOTE: You do NOT need to be a cartographer to join: this meetup is all about making time to work on things you’ve wanted to do for a while and keep putting off. Motivation by meeting up with others virtually and enjoying trying new things, building, creating - together!

I’ve wanted to do this - both relaunch #creativeCarto for community connection 🥰 and to be inspired and learn from all of you too 😍, but also because I really have wanted to be like so many others in geospatial who freely share information regularly Both of these things had such an impact on me

For the #30DayMapChallenge Day 17 prompt "A New Tool", we played around with Eduard to make a monochrome map of Colorado. While we bought our Eduard license years ago and have used it before, we're going to sneak it in as "new(ish)" with this prompt!

For the #30DayMapChallenge Day 15 prompt "Fire", we failed at our self-given goal to keep things quick and simple and went down the rabbit hole to visualize the 2021 volcanic eruption of La Soufrière, Saint Vincent (which set us back a few days in prompts)

We ran out of steam to expand on this map, but for the #30DayMapChallenge Day 12 map's theme "2125" we used @noaa.gov Sea Level Rise data to visualize 10ft sea level rise in Portland, Maine (though that would be a bit of a drastic prediction for 100 years from now!)

For Day 6 "Dimensions" of #30DayMapChallenge, we are going to brag about the GIS+Blender course we took from Elizabeth Rosenbloom. After only 5hrs of learning the UI and ways to work with geospatial data within the software, we were able to make this sunrise rending of the Galapagos Islands 🌅

Just wrapped up my latest side project: my first ever map of a #NationalPark. I illustrated #IsleRoyale, which sits in #LakeSuperior, in the semiautomated hachure style I've been developing this last year. More details, and a download, on the blog: somethingaboutmaps.wordpress.com/2025/07/28/a...
A mockup of a framed image of the map. It is titled "Miinoong • Isle Royale" and has a 2:1 aspect ratio. The map is on off-white paper, and all contents are in solid black.A detail of the image, showing some of the icons in the legend and details about the projection.Another detail of the map, showing the hachures that illustrate the terrain, as well as some of the terrain labels around Greenstone Ridge.Another detail image, showing Mt.
