Data

Open Data

Open environmental data from the HICS station network. The instruments are still in development, so there are no public readings yet — the ingest API and this dashboard go live when the first field unit is deployed.

No public data yet — the network isn't logging.

IESH v0.1 is in bench testing in Kathmandu. The ingest API, this dashboard, and the CSV/JSON downloads are all built and waiting. The moment the first field unit posts a reading, the charts below populate automatically.
