From Source to Product Signal

Test a Product Idea in Four Steps

Meteo LT publishes current measured water levels at named hydro-stations in centimeters. Start with one documented station; a water level without a station datum or official threshold is not a flood warning.

1

Check the Setup

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

Access the Data

  1. 1.Read the hydro-station endpoint documentation and CC BY-SA terms.
  2. 2.Fetch the latest observations for one documented station.
  3. 3.Keep its UTC observation time, station name, and water-level unit together.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import requests

response = requests.get(
    "https://api.meteo.lt/v1/hydro-stations/nemajunu-vms/observations/measured/latest",
    timeout=20,
)
response.raise_for_status()
data = response.json()
for observation in data["observations"][-2:]:
    print(data["station"]["name"], observation["observationTimeUtc"],
          observation["waterLevel"], "cm")

Test a Useful Signal

Inspect One River Station

Show one recent Lithuanian station water level with its time and unit.

  1. 01Fetch the documented station's latest measured observations.
  2. 02Display its station name, UTC time, and centimeter level.
  3. 03Explain why the value cannot be treated as an official flood warning.
