From Source to Product Signal

Test a Product Idea in Four Steps

IMGW's public API returns river-stage measurements with official warning and alarm thresholds. Free access is limited to qualifying noncommercial analysis; commercial and specified sectoral uses can require a separate agreement and payment. Start with five stations from one response. A threshold crossing at one station is not a published area-wide warning.

1

Check the Setup

  • Python 3.10 or newer
  • An internet connection
  • The requests Python package
2

Access the Data

  1. 1.Read IMGW's current access regulation before reusing observations.
  2. 2.Fetch one current hydrology API response.
  3. 3.Inspect station ID, measurement time, stage, and warning threshold.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import requests

response = requests.get("https://danepubliczne.imgw.pl/api/data/hydro/", timeout=30)
response.raise_for_status()
for station in response.json()[:5]:
    print(station.get("id_stacji"), station.get("stan_wody"),
          station.get("stan_ostrzegawczy"), station.get("stan_wody_data_pomiaru"))

Test a Useful Signal

Inspect Polish River Thresholds

Review five official station readings before local stage matching.

  1. 01Keep station ID, river, reading time, units, and both thresholds.
  2. 02Reject stale, missing, or malformed readings before comparison.
  3. 03Explain why a station reading does not equal an official area warning.
