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National #Sticker Day (Jan 13) by sharing my freshly made homemade #map stickers (randomly placed), including some unpublished ones.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!😉

#30DayMapChallenge | Day 8 Urban | This is an HDF laser-cut 3D #Madison city flag, which also reads as a city map, including the two lakes and an isthmus land, with a four-wing capitol building at center. I gave it a watercolor coat and made it as a magnet. What a little Madison souvenir!

#30DayMapChallenge | Day 11 Minimal Map | I turned my Day 3 recolored AI-generated low-poly map of the contiguous US into a simple #watercolor painting. It's fun when a rough handmade meets futuristic low poly, but staying faithful to satellite imagery terrain colors instead of AIGC made-up details.

#30DayMapChallenge | Day 10 Air | This is an exploratory bivariate map illustrating global temperature patterns based on WorldClim bioclimatic variables: annual mean temperature (BIO-1) and annual temperature range (BIO-7). Read more: cartoguophy.com/maps/global_...

#30DayMapChallenge Day 9 Analog | I’m an amateur Irish tin/low whistle player. I previously made two tiny #Ireland #LEGO maps with 30×30 km cells and 75 m per vertical brick. I gave one away to MUSO, my Madison Irish music session, and keep the other with me for attending LEGO community events.☘️🪈

#30DayMapChallenge Day 7 Accessibility & 8 Urban | #Atlanta #Metro (#Marta) Map | It's challenging to represent linear features using LEGO, due to its low resolution and limited angular flexibility. This map illustrating Atlanta’s MARTA lines and I-285 shows the potential of this mapping approach.🚊🏙

#30DayMapChallenge Day 5&6 I just completed my first #globe design, a virtually rendered #LEGO cube globe! The colors were derived from a pixelated Natural Earth raster layer (Cube Projection). As usual, I applied manual cartographic curation to preserve recognizable geography. Hope you enjoy it!

#30DayMapChallenge Day 4: My Data. I spent a special summer interning at #Apple Maps—my first time in the #BayArea and first time exploring a place ( #Cupertino) entirely by #bike. I meant to just map my rides, but ended up refining many details (still ongoing) as it was such a rewarding experience!

#30DayMapChallenge Day 3: Polygon (Low-Poly US Terrain Map) I love #LowPoly graphics, so I asked ChatGPT to generate a US map and then filled each triangle in #Photoshop with a single color roughly sampled from satellite imagery. It is abstract, simple, and surprisingly joyful!

#30DayMapChallenge Day 2: Line ( #Shanghai #CityWalk Route Map Series) Shanghai Dérive (魔都漂移) is a #PublicHistory project exploring how history lives in urban space, where I designed event maps, linking routes, places, and memories through geography. View more: cartoguophy.com/maps/shangha...

#30DayMapChallenge Day 1: Point 🍑✨ This was one of my early explorations in #LEGO mapping, back in Spring 2024. Now I turned this design into a 3D model using round tiles (flat points), creating this "flat" 3D map of #Georgia. View more: cartoguophy.com/maps/lego_ge...

#30DayMapChallenge This November is turning out to be one of my busiest months ever, but I really don’t want to miss out on this amazing party. I might join a few days late or randomly here and there, but that’s part of the fun! Hope to share some extra mappy joy with you all! 🌍🗺️✨

Happy 80th Birthday (1945.10.24-2025.10.24), #UnitedNations !🌐 I made this quick map as a small cartographic tribute to mark this milestone. Grateful for my previous internship at @undp.org ✨

🌎I’m actively seeking full-time roles as a #Cartographer (on-site / remote). With rich experience in cartography & GIS, my work has been widely recognized with 70+ achievements (CartoGuophy.com). If your team’s hiring or you know openings, I’d truly appreciate any referrals or shares! #OpenToWork

Sharing my latest map: Scenic #Yosemite National Park, as a cartographic tribute to the birthplace of the national park idea. The design style is inspired by #NationalParkService. Read more and download for free: cartoguophy.com/maps/yosemit... Feedback is highly appreciated!

Grateful for honoring me with this award! This map visualizes our personal footprint in the US. It is not a grand story or made to serve many, but it carries a message: maps are not only for experts or institutions; they can hold our own stories and memories. Updated: cartoguophy.com/maps/footpri...

I created this guide map for our historic tour by Shanghai Dérive 魔都漂移, following the photographs of a renowned journalist and photographer (a UW-Madison alumnus) to uncover historical moments in Shanghai during WWII. Follow our WeChat and RedNote account for more details.

Thank you to Avenza Systems for their support in sponsoring the best electronic map award 2025. Congratulations to the three runners up in this category: Wuhan University, British Antarctic Survey and Atlas Guo.

As my #AppleMaps internship wraps up, I feel incredibly grateful for the journey—full of learning, growth, and new perspectives. Huge thanks to my colleagues for their constant support and encouragement, and to the many talented new friends who inspired me to think bigger and #ThinkDifferent!💡

This past week, my map was on display at #ICC2025. It was my 2nd time with work at ICE, but the 1st time as a physical poster. (Thanks to my Apple & UW colleagues for photos!) After several U.S. showings, I’m excited that it had the chance to contribute to global public awareness of #disasters.

www.sco.wisc.edu/2025/07/22/c... Thanks for featuring me! I'm sharing another submission, centered on lesser-known WI counties of Menominee and Shawano. As a client project in UWCartLab, this map traces historic railroads and their conversion into trails. A large print is at the Trailhead Center.

www.maps.com/atlas-guo-di... Many thanks to Maps.com for the kind feature and interview about my U.S of Natural Disasters map (cartoguophy.com/maps/us_natu...) and other thoughts on cartographic design. I deeply appreciate the opportunity to share my work and passion for mapping! ❤️🗺️
