## Works, lab tools & talks
- [Re:Earth Visualizer](https://surreal.red/en/work/2020-re-earth-visualizer/) — 2020, tags: software, commercial. Open-source 3D GIS platform built from zero since 2020 with a small team at Eukarya. Officially adopted by Japan's MLIT PLATEAU initiative; runs daily across ~20 municipalities. visualizer.reearth.io · reearth/reearth-visualizer.
- [cog viewer](https://surreal.red/en/lab/cog-viewer/) — 2026, tags: lab, software. Browser-based viewer & analyzer for Cloud Optimized GeoTIFFs. COG-aware fetching, multi-band compose, histograms, elevation profiles. Drop a URL or local .tif and inspect — then copy a Python snippet to continue in Jupyter.
- [csv doctor](https://surreal.red/en/lab/csv-doctor/) — 2026, tags: lab, software. Browser-based CSV cleaner & WebGIS converter. Auto-detects encodings, normalizes Unicode, exports to GeoJSON / CZML / KML. All processing local — files never leave your browser.
- [STAC Lens](https://surreal.red/en/lab/stac-lens/) — 2026, tags: lab, software. Browser-only viewer and health checker for any STAC catalog or API — the shape of the data, where the metadata contradicts itself, and what the API actually does when asked. Paste a URL; nothing is uploaded.

Can a delivered point-cloud dataset become something people keep using? Kofu City — 212 km², 9.6 billion source points — re-published as one COPC file and two COGs: no downloads, about $3 a year to keep online, and one STAC URL as the front door.
- [Beyond the Map — Designing GIS to Help People Understand the Places They Live (Beyond the Map —— 让人理解自己居住之地的 GIS 设计)](https://surreal.red/en/talk/foss4g-2026-beyond-the-map/) — 2026, tags: talk. Three stories — a flood, a festival, a classroom — about designing GIS for understanding rather than information.
