ALT Title card reading “Proteus”, new paper in GeoInformatica by Raunak Sarbajna. The right half shows a map of Downtown Houston streets from OpenStreetMap after a simulated disaster with 32 simulated volunteers. Most streets are drawn in green as the map Proteus rebuilt, a few destroyed streets are red dashed lines, and orange circles mark the intersections Proteus detected.
ALT Bar chart titled “How many volunteers must confirm a road?”, showing the share of road edges Proteus reproduced in simulation. University of Houston campus: 35.2% with 2 volunteers, 90.1% with 3, 89.5% with 5. Downtown Houston: 40.8% with 2, 85.6% with 3, 92.8% with 5. A large “4×” on the right notes that assigning each volunteer a quadrant covered the UH campus four times faster than spreading them over the whole map: 1,400 vs 5,600 time steps. Source: Sarbajna, Eick and Ni, GeoInformatica 30:7 (2026), Tables 2 and 5.
ALT Screenshot of the Proteus demo at crowdsensinglab.org, headed “Try Proteus in your browser”. On the left are controls for the area, the share of roads destroyed, the number of volunteers and GPS noise. On the right is a rotated street grid with the rebuilt map in green, destroyed roads in red and detected intersections circled. Results below the map include 100% of passable roads recovered and 97% of the Proteus map passable.
ALT A tribute to one of the most poignant scenes from the epilogue, in Tenereal e.4: “A memorial?” Vista asked, laying a hand against the largest stone. “Yeah.” “Can I ask who for? Or is that a dumb question?” “Dumb question,” Rachel said. She leaned back, resting her head against the stone behind her. When Vista didn’t respond, Rachel relented. She pointed at where the two trees rested against one another by the cliff face. “When the weather was warm, there was a bee’s nest there. The buzzing doesn’t bother me as much as you’d think.”

ALT Screenshot of the game Where on the Moon?: a grey lunar landscape with a bright hill on the horizon, next to six smaller map images of similar terrain
ALT The same game round after answering: map image 2 is outlined in green as correct; labels show the player and the Earth-trained AI chose it, while the rover AI chose image 6
ALT Eight renders of one lunar location with a hill on the horizon. Shadows lengthen and flip, and brightness changes, as the Sun position changes
ALT Sun Lab screenshot: the rover’s view under a low eastern Sun with long black shadows, next to the evenly lit map image; the model ranks the true place 14th of 15
ALT Bar chart of the share of lunar views placed correctly: CosPlace 26.8%, EigenPlaces 28.1%, DINOv2-SALAD 35.8%, Galatea frozen 59.8%, NetVLAD fine-tuned 76.4%, full system 78.8%
