Who is joining in on #CreativeCarto today?? I got the kiddo set up with her own CreativeCarto mapping, I printed out maps I made for the BirdsCaribbean Endemic Birds Coloring Book and gave her a blank page and some map stamps from Lord of Maps! Now what should I work on ...?

We will not be conducting any freelance work on Friday, January 30th in solidarity and protest:

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!

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 21/11/2025

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!

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 21/11/2025

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)

0111

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 21/11/2025

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!)

0162

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 21/11/2025

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)!

062

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 11/11/2025

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.

171

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 11/11/2025

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 jewelry@tombolomapsdesign.com!)

051

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 11/11/2025

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".

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 09/11/2025

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 🌅

0131

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 09/11/2025

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!

0101

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 09/11/2025

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 😉)!

021

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 09/11/2025

For our next map for the #30DayMapChallenge, for Day 3's prompt "Polygons", we made a quick map of Burlington, Vermont!

072

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 09/11/2025

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.

021

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 09/11/2025

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!

Just a few more issues until we're caught up to the present. Today is Issue #102 (2023), and a cover by Aly DeGraff Ollivierre (@alyolli.bsky.social / www.tombolomapsdesign.com) of the island of Carriacou, in Grenada. cartographicperspectives.org/index.php/jo...

The cover of an issue of Cartographic Perspectives. The top portion of the cover lists the journal name and issue date. The lower 80% or so shows a relief map of Carriacou. Nearby smaller islands are shown and labeled, as well as towns on the main island. The text is in a casual typeface that resembles hand-labeling. The background color is watercolored and varies. The whole cover is monochrome gold.

Page #2 from the issue. It is titled "About the Cover" and shows the original, full-color version of the map. It reads:
"This issue features a detail from a wall map of Carriacou, Grenada, by Alison DeGraff Ollivierre. This map is part of a series of wall maps, which together cover the terrain and settlements of the transboundary Grenadines. You can see more of Aly's work at www.tombolomapsdesign.com."

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 27/11/2024

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!

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 25/11/2024

Happy belated GIS day! We're honored to have our map of the "Passage of Hurricanes Impacting the Grenadines" featured on the cover of the Caribbean Geospatial Voices Newsletter, Issue 2 (caribbeangeospatialvoices.com)

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 24/11/2024

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!

0101

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 24/11/2024

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.

041

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 24/11/2024

Day 20 of the #30DayMapChallenge for the prompt "OpenStreetMap (OSM) data" and we're resharing a quick map of Soufrière, Saint Lucia that @alyolli.bsky.social made just-for-fun in 2016!

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

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!

0181

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

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!

051

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

For Day 14 of the #30DayMapChallenge, Rachael Carpenter made a map of the ten largest #rivers in the world by discharge volume for the prompt "world map".

031

Day 13 of the #30DayMapChallenge and Rachael Carpenter took the opportunity to experiment with #Eduard Relief Shading software for the prompt "a new tool" to map #volcanoes in #CentralAmerica along the #tectonicplates!

061

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

Day 12 of the #30DayMapChallenge’s prompt is “time and space” and we’re republishing @alyolli.bsky.social’s map that she originally made in 2016 by digitizing Mississippi meander belts mapped by cartographer and geologist Dr. Harold Norman Fisk in 1946 and overlaying them on his original map.

0132

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

We’ve got a second post for Day 11 of the #30DayMapChallenge: Rachael Carpenter mapped sea ice extent in the arctic during the fall and spring equinoxes!

061

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

Day 11 of the #30DayMapChallenge’s prompt is “Arctic” and we’re resharing a series of 14 projections of Svalbard, Norway that we overlaid on one another for artist Perri Howard of Velocity Made Good in 2020 which she then had etched on a magnesium plate and printed as a letterpress edition!

011

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

Day 10 of the #30DayMapChallenge’s prompt is “pen and paper” which @alyolli.bsky.social tried her hand at in a fun “C-ART-o Camp: Exploring Art Materials and Methods” workshop with Molly O'Halloran and @sarahbell.bsky.social at the @nacis.bsky.social Conference in 2018.

052

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

Day 9 of the #30DayMapChallenge’s prompt is “AI only” and @alyolli.bsky.social used it as an opportunity to test out Adobe Illustrator’s Generative AI Text to Vector Graphic Beta Feature. She tried “tombolo” as the prompt phrased in different ways and put the best results together to share!

051

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

Day 7 of the #30DayMapChallenge’s prompt is “vintage style” and we’re going to post another that @alyolli.bsky.social made just-for-fun in 2018 of #Portland, #Maine which was also published as part of the 2019 #GeoHipster calendar.

061

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

Day 5 of the #30DayMapChallenge’s prompt is “a journey” and (while we love this prompt) we don’t have the time to make a new one today, so we’re posting about one @alyolli.bsky.social originally created in 2019 for Guerrilla Cartography's “Atlas in a Day: Migration”.

011

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

041

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

Day 3 of the #30DayMapChallenge and @alyolli.bsky.social took the opportunity to use the prompt “polygons” to map the World Time Zones (since today is Daylight Savings Day)!

011

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

Day 2 of the #30DayMapChallenge and @alyolli.bsky.social made a quick map of #SouthAmerica's #waterways for the prompt "lines" today!

041

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

Going to start by back-posting #30DayMapChallenge posts! Day 1's prompt is "points", which led @alyolli.bsky.social to make a map of #LakeChamplain with mini inset maps of every single point geographic feature with "Point" in its name (e.g. Shelburne Point) within #Vermont's borders of the lake.

0122

Tombolo Maps & Design @tombolomapsdesign.bsky.social · 19/11/2024

It's been incredible to have Rachael on our team for the past year, we're looking forward to many more!
