Data source
OpenHI / Enhydris public API on https://system.openhi.net/api/ . Public portal: https://openhi.net/en/ . API references: https://system.openhi.net/api/ and https://enhydris.readthedocs.io/en/latest/dev/webservice-api.html . Data licence: CC BY-SA 4.0 https://openhi.net/licence/ .
Type of data portal
This is a public historical time-series API and does not require authentication for the station, timeseries group, timeseries, or CSV data endpoints. Historical retrieval works through /data/ endpoints with start_date / end_date and fmt=csv.
Useful discovery endpoints:
Country/Countries/Regions
Greece
Variables
The hydrometric variables currently verified are:
- stage / water level (
Stage, Water Level)
- discharge (
Discharge)
Station list
The station list can be discovered from the public station search endpoint. The most useful approach appears to be taking the union of:
ts_only: variable:stagets_only: variable:levelts_only: variable:discharge
The station search results include station id, station name, geometry, owner, and provider date fields. Timeseries coverage then has to be mapped via:
/api/stations/{station_id}/timeseriesgroups//api/stations/{station_id}/timeseriesgroups/{group_id}/timeseries/
Verified examples:
At the moment the ts_only search appears to return about 64 candidate stations, with hydrometric coverage of roughly 42 stage / water level stations and 8 discharge stations.
Code snippets
Implemented in the branch greece.
