After many requests for phone viewing, I added a mobile mode to my award-winning map “Climate Visualized.” The interface now fits phones, tablets, desktops, and ultra-wide screens.📱 Suggestions are greatly appreciated: cartoguophy.com/climate-visu... #climate #cartography #dataviz

Recently I tested a new design style for my North America #LEGO #topographic map, but I am not sure which works better. Which one do you prefer? A. Individual round tiles B. Continuous surface tiles

I was told that before sunrise on 3/3 we might catch a #BloodMoon (#TotalLunarEclipse), just coinciding with the Chinese #LanternFestival! 🏮🌕 (next time in 2054...) Unfortunately, thick clouds hid the moon, so I turned to my #LEGO moon again and turn it into a blood moon 🌝

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? 🟨🟡

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! 💌🗺️ #HappyValentinesDay #ValentinesDay #Valentine

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? See more of my #LEGOmaps on dedicated page: cartoguophy.com/lego.html

🐿️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 .🌦️ cartoguophy.com/maps/koppen....

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. Source: NASA Black Marble Nighttime At Sensor Radiance. 🛰️❄️🪫🗺️ #WinterStormFern #DataVisualization

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

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

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! 🗺🚲 #map #cartography #LEGO #cycling

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...

Just made a #Christmas themed #LEGO #Madison map with a touch of holiday humor. Merry Isthmus!🎄 #MerryChristmas #MerryIsthmus #HappyHolidays

#30DayMapChallenge | Day 26 Transport | After Atlanta, I made another #LEGO transit map of #Madison Metro Rapid BRT. Smooth lines failed on diagonal routes, so I returned to a pixelated version. I spent really long time designing the capitol building, and hope it serves as the finishing touch! 😊

#30DayMapChallenge | Day 29 Raster | Another experiment in large scale thematic #LEGO mapping. With a 0.1-mile grid, I built a citywide 3D elevation map and colored the top tiles of each cell by category. Colors reference the #Lawrenceville 2045 Character Areas map (www.lawrencevillega.org/241/Maps)

Today marks the 9th anniversary of being together with my wife since 2016. Over the years, our travels have covered 38 states, turning places into our spatial memories. This map was honored to win the Ordnance Survey Student Award from BCS @bcsmaps.bsky.social 🌐 (cartoguophy.com/maps/footpri...)

#30DayMapChallenge | Day 18 Out of This World | #LEGO #Moon Map. It's fun mapping a totally different landscape with my LEGO approach: abstract, cute, yet roughly accurate. With no oceans on the Moon, I used a uncommon color scheme for topographic maps. Source: Wikipedia #Selenography

#30DayMapChallenge | Day 16 Cell | #LEGO Map of Georgia Bulldog | Big congrats to #Georgia #Bulldogs football team for beating Alabama to win the #SEC Championship! 🏈

#30DayMapChallenge | Day 6 Dimensions | I colored my #lasercut #Wisconsin 3D #topographic map. Though the natural HDF wood tone limited the choice of colors, the dark edges did enhance the 3D effect. Watercolor was used to fill up the valleys. (The digital file was shared to local blind school.)

#30DayMapChallenge | Day 21 Icons | This prompt reminds me of the #LEGO #AppleMaps icon I created this summer, which displays Apple Park at Cupertino. Recently, I experimented with another major competitor, #GoogleMaps, though sadly its icon is not a map.

#30DayMapChallenge | Day 22 Natural Earth Based on my earlier #chromostereopsis globe, I made another #stereogram centered on the Western Hemisphere. Use the magic-eye parallel view at phone-screen size to see the 3D effect. It can be very tough, so don't force it since it may strain your eyes🫨

#30DayMapChallenge | Day 23 Process | #Procreate #DigitalWatercolor #Taiwan Island My first iPad painting! Still struggling with the Apple Pencil, but it was really fun with only a bit of real #watercolor experience. I exported a GIF of all my layers, even though I really didn’t need that many.

#30DayMapChallenge | Day 19 Projections & 22 Natural Earth | I created a fun “shaking” earth graphic based on #chromostereopsis, a color-based depth illusion in which red and blue light fall on slightly different spots in the eyes, creating a horizontal offset that our brain interprets as depth.🌐👀

#30DayMapChallenge | Day 25 Hexagons | My multivariate map tile for 2025 @NACIS #MapQuilt visualizes the risk of 18 natural hazards in southern #Louisville. Each 200-acre hexagon’s score is aggregated from #FEMA NRI at the census-tract level. More info: cartoguophy.com/maps/multiha....

#30DayMapChallenge | Day 20 Water | #LEGO #Bathymetric Map of #GreatLakes. Visualizing 3D #bathymetry is much harder than the terrain, and I tested a lot of versions before choosing this style. I also tried some new designs for the map frame, north arrow, and legend. Feedback welcomed! #cartography

I was delighted to introduce cartography to students from Central Gwinnett High School at City of #Lawrenceville #GISDay, using my LEGO maps to share the joy of mapmaking. It was my first time speaking to younger audiences. I hope the experience sparked their curiosity about geography and maps.✨

#30DayMapChallenge | Day 27 Boundaries | A virtually rendered #LEGO map of the #BritishIsles, with each area in its own color and elevation shown by stacked plates. I also added an inset map for the first time, following the terrain style from my well-received #Arizona map.

#30DayMapChallenge | Day 24 Places and their Names | Latest map for public history project #Shanghai Dérive 魔都漂移 #CityWalk. This chapter traces the “Lone Island” in years 1937–1941, revisiting key resistance plates through on-site walks. More details: mp.weixin.qq.com/s/I09Hb52YtA....

#30DayMapChallenge | Day 15 Fire | This is a fire in the literal sense. The 43-hour blaze in #HongKong was a true disaster, and I created a map to document it. The style sits between a rapid-response news map and a detailed event map, in both English and Traditional Chinese. Pray for all affected.🕯️

#30DayMapChallenge | Day 28 Black | I painted the #hillshade around #SanFrancisco using black #watercolor. After adding some light colors for land and sea, it looked like an old map, which was really fun. Then I wrote some place names in a vintage type style to match this style.

#30DayMapChallenge | Day 17 A New Tool | AI-generated “ancient style” map of Madison using #NanoBanana Pro🍌. Still has typos and shaky lines, but already far better than early AI maps. #AI is moving from pure inspiration toward practical cartographic tool. The Age of AI has begun~

Proudly showcasing my LEGO and natural disaster maps at the #UGA #GISDay, where I also served as a map poster judge. I was one of the student organizers (Chair of Logistic Committee) in the 1st campus-wide UGA GIS Day, and it's a true honor to return as an alumnus and witness its ten-year milestone!

#30DayMapChallenge | Day 13 10-minute map | Tiny #LEGO #Georgia Map I didn’t have my LEGO elements with me, so I used whatever pieces I had to build a tiny Georgia map. It’s probably the least geometrically/topologically accurate LEGO map, but it's still a strong candidate for the cutest one. 😅🍑

Had a wonderful day at Cobb County (GA) #GISDay sharing my #LEGO maps and U.S. #NaturalHazard visualizations. I truly enjoyed the conversations and loved seeing people discover info or fun moments through the maps. Huge thanks to the organizers for the invite and the great event today! 🗺️✨

#30DayMapChallenge | Day 12 Map from 2125 | TBD Imagining a map 100 years ahead is tough. I’ve got ideas to share later, just not today. For now, here’s a map I made last year for 100th anniversary of my alma mater, Sun Yat-sen University #SYSU on Nov 12, birthday of Dr. #SunYatSen, father of ROC.

This Friday 11/14, I will be attending Georgia's Cobb County GIS Day event with a booth sharing many physical and digital LEGO maps (similar to but more than this photo), several U.S. natural disaster map posters, and FREE LEGO map stickers! Looking forward to the event!😉
