So these researchers figured out you can basically hallucinate 3D cities into existence using just satellite photos & a diffusion model.
The problem's pretty straightforward: satellites only see rooftops. Building facades? Invisible. Street-level detail? Doesn't exist. But people want flyable 3D environments, which means you need all that occluded geometry.
When I worked on google maps photogrammetry, we could only use satellite-based 3D for isolated stuff like the pyramids - anything city-scale required airplane flyovers. Which is fine until you hit aerial-denied regions where you literally can't fly. Huge chunks of the world just unavailable.
Their trick is honestly kind of beautiful. They train gaussian splats on satellite views, but as it descends toward ground level, the renders turn to absolute garbage - artifacts everywhere. Instead of fighting this, they just treat those nightmare renders as the input to a diffusion model. Basically - "hey FLUX, fix this mess."
Then here's where it gets clever: they generate multiple diffusion samples per view instead of committing to one. Because any single denoising path is probably wrong in 3D space, but if you generate a couple and let the GS optimization find consensus across them, you get actual geometric consistency.
They do this in episodes, curriculum style - start high, gradually descend (hence the name Skyfall-GS!). With each iteration the ground-level views get less fucked. By the end you've got real-time flyable cities that look surprisingly real, and the geometry still matches the satellite input.
No 3D training data. No street-level photos. Just satellites + diffusion doing what it does best - filling in the blanks. It's like neural scene completion but actually practical, and it unlocks basically the entire world.

Well, it turns out that this approach used by @sidahuj (genius!) for Blender CAN ALSO BE USED WITH QGIS!!!!
So, my friends, I present to you "MCP QGIS," which gives Claude access to use QGIS directly!
The era of "vibe mapping" begins. See how it works:

🧩 Built an MCP that lets Claude talk directly to Blender. It helps you create beautiful 3D scenes using just prompts! Here’s a demo of me creating a “low-poly dragon guarding treasure” scene in just a few sentences👇

RailScan Multi-Function Robot: Railway Surface Inspection
The RailScan robot is designed for track inspection, using a self-moving platform and precise sensors to quickly detect track defects. It assists track inspectors with nighttime inspections, addressing challenges in traditional manual inspections such as heavy workload, missed detections, and difficult tasks. The robot helps reduce inspection costs, improve efficiency, and enhance safety by identifying potential hazards in the rail track.

Why do school maps have to be so ugly?
My kids have been filling out maps as part of their homeschool curriculum…but they just look so sterile. So, dad can’t help himself and is stepping in!
I won’t be going all out with mountains and jungles and such because it needs to stay clean enough that you can easily write in names without too much visual chaos.
But, I want to also add some banners to make it easier for them to see what needs to be filled in. Because that was an issue on the original map.
Let me know what you think so far!
