Thank you!

So happy to receive the printed #ArcUser! Seeing my work in a magazine that reaches hundreds of thousands feels exciting and humbling. Thanks again #Esri for helping this little #LEGO #cartography experiment reach more people. Grateful for readers’ kind messages too! 😊 www.esri.com/about/newsro...

As a #Pokemon enthusiast, I rebuilt #Kanto region as a LEGO-style map to celebrate 30 years of #Pokémon, first introduced with Red/Green on 2/27/1996. Map based on FireRed & LeafGreen, with badges inspired by #LEGO set 40892. Made this pretty quickly tonight, so let me know if I got anything wrong~😊

Sharing a recent research byproduct: rounded 1M-pop gridded #cartogram based on 2025 #population, totaling 342 units. It's not easy to balance recognizable state shapes with accurate adjacencies. In #LEGO form, I also added cities in 1M-pop increments. Which of the two styles do you prefer? 🟨🟡

@johnnelsonmaps.bsky.social This is fun!

Since I displayed my customized North America Map at a #StarWars themed #LEGO event on “May the 4th” (“May the Force be with you”), it has received so much love that I later added a #MillenniumFalcon to join the fun. The map highlights the filming locations around North America.

Heart-shape world map again, but with #LEGO! 💌🗺️

Introducing ClimateVisualized, my latest #webmap to visualize global #climate & #Koppen classification system on a 1° grid using monthly #temperature and #precipitation data. Try the "climate glyph" mode to explore monthly patterns in a creative way. (Desktop viewing recommended) #DataVisualization

On Feb 7-8, I brought my #LEGO maps to #AtlantaBrickCon, my first convention of this kind. In a world obsessed with size, my maps felt modest, but many visitors offered kind praise and saw strong educational potential. Interested?

🐿️Today (2/2) is #GroundhogDay, a folk tradition to forecast the winter using a simple sign. In terms of #Climate, I recently designed a glyph-based map visualizing the global pattern using Köppen classification, embedded into a #DataVisualization #inforgraphic .🌦️

Unexpectedly, the #WinterStorm web map I built last week becomes useful again so quickly: another cold outbreak is forecast for #NorthCarolina, #SouthCarolina, #Georgia, and #Virginia this weekend. Note: this dataset (WSSI) shows potential impacts and does not replace forecasts. ⚠️❄️

Jan 28th is #InternationalLEGODay. I was preparing prints of my #LEGO maps for next weekend’s #AtlantaBrickCon, one of the largest LEGO fan conventions in the U.S., with 10K attendees in a nearly 100K sq ft venue. Excited to share my physical maps and these digital designs there! 🧩🗺️ #Cartography

I used satellite imagery over #Nashville, #Tennessee from before (1/22) and after (1/27) the recent #WinterStorm to estimate #PowerOutage at a finer spatial scale, based on changes in nighttime radiance.

Thanks! It's ArcGIS Pro + Illustrator.

I made a map visualizing the customer count and percentage of #PowerOutage as of 6 AM CT on Jan 26, following the severe #WinterStorm over the weekend. #Nashville stands out as the hardest hit area in terms of outage numbers. #WinterStormFern #DisasterMapping #DataVisualization

Thanks for your kind words! Stay safe😊

Thanks! It uses ArcGIS's JavaScript SDK.

I tried to update my #WinterStorm maps more frequently during these critical days❄️, but NOAA’s data was updating even faster than expected. So I turned it into a web map, so anyone can check the impacts for the next 1–3 days: cartoguophy.com/winter-storm/ (desktop viewing recommended)

Increasing hazard situational awareness is always worthwhile, and disaster maps are never excessive. I made this US #WinterStorm map with a dark background (save battery during outages), a vertical layout (mobile viewing/sharing), colorblind friendliness, and county/city references. Source: #NOAA

Thanks for your like! I will post a new version with dates clearly labeled.

Updated my Historical #Hurricane Tracks map, plus a 2025 highlighted version. The 2025 #AtlanticHurricaneSeason saw no major hurricane make landfall in the U.S., but #Jamaica was severely impacted by #HurricaneMelissa. More info: cartoguophy.com/maps/histori....

Joyfully celebrating National #Sticker Day (Jan 13) by sharing my freshly made homemade #map stickers (randomly placed), including some unpublished ones. They fall into several categories: #LEGO based, hand-drawn, reference map, and fun graphics. Let me know if any particular ones stand out to you!

Mappy New Year 2026! 🗺🚲

Wrapping up 2025 with my #30DayMapChallenge, finished in two months. Grouped results show #LEGO leading with 12 maps, traditional #GIS at 11, craft and painting at 6, plus one #AI generated map (1/3 entries used AI tools). Looking forward to my journey of #cartography in 2026! Happy New Year! 🎨🗺️

#30DayMapChallenge | Day 14 OSM | This map challenges the idea that streets belong to cars, even so-called sharrows that still feel unsafe. Using an inverted speed-limit hierarchy, fast roads fade. Bold bike infrastructure reveals how broken and fragmented the biking network is.

#30DayMapChallenge | Day 30 Makeover | During #NACIS 2025, I tried colored-pencil sketching and drew my own #Yosemite map on the gallery panel. Recently, I revisited it by recoloring with watercolor to strengthen the shading and adding some labels. ⛰🖌 Original map: cartoguophy.com/maps/yosemit...
