"Symmetry is what this kind of mapping aims for: not mapping in a way such that the map is symmetrical to the world, but in a way that the map is symmetrical to what humans know about the world."

Suddenly I wonder if you can spot my house from space by my heat signature while running Codex
Gas generators run hot. With thermal satellite imagery on SkyFi, you can see which data centers are actually powered up, day or night.

「LLMがGISを操作する仕組み」と「空間データを学習するモデル」が”GeoAI”として一括りに語られることが増えてきました。
最近の潮流を受けて、「GeoAIは結局LLMに置き換わったのか?」という問いを次の4つの役割に分解して整理しました。
① 認識・予測(空間モデル)
② 言語対応(VLM・地名解決)
③ 計画・操作(LLMエージェント)
④ 接続(MCP・API)
「GeoAIを使った」の一言で思考停止しないための境界線を書いています。

Speeding through the Gotthard Base Tunnel (train) and still have 5G. Did lose connection for a moment.

But @swisstopo doesn't fetch my location?

Ciao Ticino 🇨🇭

I want to visit all of them
うっすら寒くなってきたので、日本全国の温泉を可視化してみた。
全体的に、活火山の集中地帯では熱々のお湯がたくさん湧き出る傾向。
11月のお休み、どこの温泉に行こうかな?と調べているうちに、どんどん時間が経っていく・・・。

I need to find a use for this in terms of improving maps, lot of new possibilities arising
物体名ではなく、他の物体との関係で探す「RelationVGGT」🌐

🔹別角度の画像からも対象を切り出す
🔹カメラ姿勢情報・シーンごとの最適化は不要
🔹平均mIoU 0.303→0.382(約26%向上)

I have been busy mapping bus stops in Slemani in hopes of creating a comprehensive Public Transport layer for about six months for @openstreetmap

I may have finally found the correct tool to do this thanks to @fotoshihq

I can’t do this all my myself…

It reminds me of Jurassic Park, the novel

The park system knows the number of dinosaurs, so using various cameras counts them constantly, outputting true or false if it counts like 275

They later realize it's counting like 700 because they are breeding, but only check T/F 275+
羊の群れをAIで追跡、通過頭数をリアルタイム集計🐑

🔹映像から羊を検出し、個体ごとの動きを追跡
🔹ゲートなど指定地点の通過頭数を自動カウント
🔹家畜の頭数管理や移動状況の把握に活用

※混雑時の追跡精度や使用モデルは未公表

Pretty cool conference, I went years ago: good place to see what's happening in tech for cities!
MapTiler has 16 free tickets to Smart City Expo in Barcelona, 3-5 Nov.

If you work on cities, mobility, or geospatial data, grab yours before they're gone!

Details in the first reply; strictly first come, first served!

This is a fact of much of Switzerland too. Tunnels are great, when they exist

Where I live it's not far to Austria but because of lack of direct roads, Italy feels way closer
Immer wieder witzig wie die Schweiz es nicht schafft die zwei Schweizer Grossstädte Bern und Luzern anständig miteinander zu verbinden.
