What does Earth photograph?

We scanned 9,487,758 public geotagged photographs from 246 countries and asked one question: when the world picks up a camera, what does it point at?

Every country. Every camera roll.

Each country is painted by the total public photos we found in it (log scale). Hover to see its most-photographed thing — cities, regions, and country names filtered out. Click for the full breakdown.

What we found

Nine things we didn't know until we ran this pipeline.

How this was built

1. The data

YFCC100M (OpenAI subset) — 15M Flickr uploads with public Creative Commons licensing, pre-sharded into 4,094 metadata files on HuggingFace. We filtered to the 9.49M rows with latitude + longitude.

2. The cluster

Burla spun up a 13-node cluster (80 vCPUs each). Peak concurrency: 967 simultaneous Python workers — each processing one shard of ~2,300 photos and reverse-geocoding every lat/lon into a (country, admin, city) tuple against a 30k-city KD-tree.

3. The map-reduce

Three passes, all on Burla: extract (118 s · 967 workers), tokenize (107 s · 640 workers), and reduce (230 s · 64 workers). End-to-end under 8 minutes of wall-clock.

4. The analysis

We scored every user-tagged phrase with TF-IDF across all 246 countries, then filtered out cities, regions, and country-name aliases so "Paris" wouldn't be France's most photographed thing. What's left is landmarks, events, subcultures, and obsessions.

Every number you see was computed from the raw data — no editorial curation. Phrases come straight from the authors' Flickr tags. See the Burla demo code.
