We are co-hosting the EAAMO colloquium next Monday (12pm EST) with Professor Rachel Franklin. Come hear her talk about spatial inequality and the smart city and feel free to share with colleagues! Register below to get the Zoom link: www.eaamo.org/colloquium/r...

#30DayMapChallenge day 24: Places and their names How often do places name other places? @mfranchi.bsky.social mapped global media attention patterns using 415K news articles from 55 countries. The analysis tracks how often outlets mention other nations. Explore at mfranchi.net/global-gossip!

November is over, but we still have some #30DayMapChallenge entries to share! And for our transport-themed day 26 map, MBTA data analyst Joe Hilleary takes us on a ride back in time: he shows current bus routes in Greater Boston by the earliest known year in which a direct percursor route ran a bus.

#30DayMapChallenge day 22: Natural Earth @lgreenstreet.bsky.social worked on a visualization of invasive species in New York State. Invasive species presence correlates with the presence of road, rail, and urban areas due to a combination of human activity introducing them and observation density.

#30DayMapChallenge day 20: water This map of Arsenic and Cadmium levels in Mexico's water show non-trace concentrations of Total and Soluble Arsenic and Cadium. Points are colored by the presence of high amounts of contaminants, and sized by their relative concentration. tinyurl.com/map20wtr

#30DayMapChallenge day 19: projections @jennahgosciak.bsky.social created a gif that visualizes NYC neighborhoods under different map projections. While most atrocities are clear only at national or global levels, her maps show interesting local deformities!

Out of this world! @eappelson.bsky.social explored fantasy map-making using rice digital to form tactile terrains for #30DayMapChallenge day 18. He was inspired by handmade maps created by outlining real piles of rice and simulated rice scattering. Grain density becomes elevation.

#30DayMapChallenge 15: Fire @sylviaimani.bsky.social visualized how Uganda’s transition toward electric cooking aligns with the reach of the national grid. Regions with denser grid networks show a strong correlation with higher household adoption of electric cooking technologies.

Are you running from your responsibilities? On our #30DayMapChallenge day 14 entry, we tell you where! Atmika Pai maps running clubs with OpenStreetMap, which includes amenities such as water and restrooms. Running club data comes from @shaylaruns (Instagram). atmikapai13.github.io/iconic-runcl...

#30DayMapChallenge day 13: 10-min map Atmika Pai set the clock. "I used Marauders, an AI-powered spatial intelligence tool, to create a heatmap of 311 indoor air quality complaints in NYC" she says. "All it took was downloading the dataset from Open Data and uploading!" tinyurl.com/13-map-311

For #30DayMapChallenge day 11, a minimal map from @kennypeng.bsky.social. Kenny extracts minimal elements from a not-as-minimal-as-it-seems object: the Manhattan street grid. "I show how Manhattan’s numbered grid of streets and avenues is more complicated than you might realize," he says.

#30DayMapChallenge day 10: Air @jessiefin.bsky.social + Francisco Marmolejo-Cossío visualize the presence of ladrilleras, or brick kilns, which emit pollution across the state. Data cleaned by Jacqueline Calderón and Lizet Jarquin at UASLP. Full interactive map: tinyurl.com/map10-air

#30DayMapChallenge day 9 asked us to get off our screens. @annaloganmc.bsky.social's "analog" map is a hand-painted postcard! 📫 "I chose to paint a postcard of a map of Ann Arbor where I currently live showing the Huron River!" she says

#30DayMapChallenge day 8: Urban Chae Won Lee uses the Overpass API to visualize current coffee shop density in New York with an interactive map. Here's a snippet.

Day 7 of #30DayMapChallenge asked us to think about accessibility. @gsagostini.bsky.social considers two metrics of access simultaneously: distance to a Subway and distance to the subway.

#30DayMapChallenge day 6: dimensions Atmika Pai dove into the ArcGIS Unity SDK to see how architects & designers plan in 3D. She explored 15 features from geocoding to viewshed analysis, all in an immersive game engine! Here's a video teaser of her map.

We might be a few days delayed on the #30DayMapChallenge, but our day 5 submission spans almost 250 years of history! Our "Earth" map comes from @jennahgosciak.bsky.social, who compared the original ecology of New York City to present day variables.

Last week, we presented the work of our group at the EAAMO conference. So, for our delayed #30DayMapChallenge day 4 (my data) we created a map showing flows from some EAAMO contributors and attendees!

We are slowly catching up to the #30DayMapChallenge! In our day 3: polygons submission, @zhixuanqi.bsky.social questioned the boundaries and fuzziness of polygons with an animated map that invites us to think about the (not-so-well-defined) idea of neighborhoods.

#30DayMapChallenge day 2: Lines Atmika Pai interpreted lines in multiple ways. Her map shows how the lines we stand in to wait for the tramway (line) generate flows lines!

#30daymapchallenge day 1: Points For our first map, we had to visualize spatial data as dots. @gsagostini.bsky.social worked on a dot density map showing dog density in New York City. 1 dot = 1 dog 🐕🐩

To get this feed started, our group will be participating in the #30daymapchallenge! On (most) days of November we will be posting a new map, by a new author, on a new theme. First batch of maps incoming... 🗺️ 30daymapchallenge.com#maps-stats
