Test a Product Idea in Four Steps

ECCC's GeoMet collection exposes preliminary AQHI observations as GeoJSON. Start with five latest features, retaining their observation times and AQHI scale. AQHI is a Canadian health-risk index and is not interchangeable with a U.S. EPA AQI or an individual pollutant value.

1

Check the Setup

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

Access the Data

  1. 1.Read the official AQHI collection description and Canadian open licence.
  2. 2.Request five latest GeoJSON items in one call.
  3. 3.Inspect observation time, geometry, and AQHI property.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import requests

response = requests.get(
    "https://api.weather.gc.ca/collections/aqhi-observations-realtime/items",
    params={"f": "json", "latest": "true", "limit": 5}, timeout=30,
)
response.raise_for_status()
data = response.json()
for item in data["features"][:5]:
    print(item["id"], item["properties"].get("aqhi"),
          item["properties"].get("observation_datetime"))

Inspect Canadian AQHI Readings

Review five reported index features before local display.

  1. 01Keep feature ID, AQHI scale value, location, and observation time.
  2. 02Check freshness and regional scope before matching a destination.
  3. 03Explain why AQHI cannot be relabeled as U.S. AQI.
