Algae Dataset
Every data hub, dataset, sensor, variable, paper and limitation in one tree — and for each: where it comes from, how far back it goes, how often it captures, why it belongs in a cholera study, and why it does not work everywhere.

Why it is used for cholera.
Operational Copernicus service with a documented validation report
Why not — catalogue limitation. Uses a FIXED global lake mask — you must confirm your specific water bodies are in it before relying on this. Likely excludes Dhaka's small urban lakes.
Site applicability
| Site | Verdict | Why |
|---|---|---|
| Chakaria HDSS | PARTIAL | CHECK COVERAGE — coastal lagoons may be excluded |
| Matlab HDSS | PARTIAL | CHECK COVERAGE — depends on the lake mask |
| Dhaka City | PARTIAL | CHECK COVERAGE — Dhaka's lakes may be too small for the 300 m mask |

Typed limitations (1)
HIGH Copernicus LWQ300 lake mask may exclude all three sites coverage
The Lake Water Quality product only reports for water bodies in its predefined mask at 300 m. Coastal lagoons are often excluded by design.
What to do: Verify coverage for your specific polygons first. If absent, this product contributes nothing and should be dropped from the plan.
