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 16 theme’s “cell" we rasterized an old map we had made of land use around Soufrière, Saint Lucia into pixels!

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 11 of the #30DayMapChallenge's prompt "Minimal" we made a VERY quick map showing off one of @pinakographos.bsky.social's Project Linework handcrafted vector linework files: Geo-Metro. If you haven't found this resource yet, it's a fun one to find uses for (www.projectlinework.org)!

For Day 10 of the #30DayMapChallenge's prompt "Air" we're resharing a map we made last year to cope with the anxiety of waiting to hear from family and friends in the transboundary Grenadines following the direct hit by Hurricane Beryl on July 1, 2024.

For the #30DayMapChallenge Day 9's prompt "Analog" we wanted to share some of the map jewelry we've made over the years, particularly our custom, handmade, geospatially accurate—but wonderfully, uniquely imperfect—jewelry. (If you're interested, reach out at [email protected]!)

For Day 8 of the #30DayMapChallenge's prompt "Urban", we refreshed a map of Kingstown, the capital of Saint Vincent and the Grenadines, visualizing the impact of 2m sea level rise on essential services downtown, that was originally published in Guerrilla Cartography's “Water: An Atlas".

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 🌅

For Day 5 "Earth" we refreshed a Pacific bathymetry map we made for our own "Map-A-Day" project (many years before the #30DayMapChallenge existed) to build up our original portfolio!

For Day 4 "My Data" of the #30DayMapChallenge we refreshed a map @alyolli.bsky.social made almost a decade ago while living in Portland, Maine after a day trip via ferry to walk around Peaks Island with two wonderful childhood friends (and a trusty old chunky Garmin GPS 😉)!

Another quick map for the #30DayMapChallenge for the prompt "Lines"! We grabbed Magnificent Frigatebird tracking data from Movebank and highlighted one of their tagged birds, "Boyd", who demonstrates the vast distances this species can explore while foraging.

We're going to try and keep things QUICK and SIMPLE for the #30DayMapChallenge this year! So here, for Day 1 of the Challenge, is our response to the prompt "Points", showing all the trees in and around Cheesman Park where @alyolli.bsky.social lived for her first half decade in Colorado!

Day 26 of #30DayMapChallenge had the prompt "projections" which of course made us think of @pinakographos.bsky.social's Projection Collection cards, so we're sharing one of the maps @alyolli.bsky.social contributed to the collection for the Cassini projection!

Another belated #30DayMapChallenge map for Day 22 and the prompt "two colors". @alyolli.bsky.social made this map of Columbia, South Carolina as a part of a triptych of maps of meaningful places for a friend for their wedding!

Posting a belated Day 21 of the #30DayMapChallenge for the prompt "conflict" to share a map concept and design by Berenbaum Jacobs Associates; with cartography by @alyolli.bsky.social; fabrication by Pacific Studio; and created for a permanent exhibit at the Dallas Holocaust and Human Rights Museum.

Day 17 of the #30DayMapChallenge’s prompt was “collaborative map” and @alyolli.bsky.social and Rachael Carpenter took inspiration from the annual @nacis.bsky.social Conference map quilt to collaborate on a map quilt of their own of #Denver, #Colorado!

Day 15 of the #30DayMapChallenge's prompt is "my data" and we're republishing @alyolli.bsky.social's map that she made in 2016 of a ferry ride to and hike around #PeaksIsland off the coast of #Maine with friends!
