From Source to Product Signal

Test a Product Idea in Four Steps

EAWS publishes a maintained composite GeoJSON and smaller country or subregion partitions. Start with the AT-02 partition and two polygons; matching a destination to a polygon does not establish that a bulletin is active or applicable at its exact location.

1

Check the Setup

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

Access the Data

  1. 1.Read the EAWS geometry index and source-repository CC0 licence.
  2. 2.Download one bounded microregion partition.
  3. 3.Inspect feature IDs and geometry before joining to bulletins.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import requests

url = "https://eaws.gitlab.io/eaws-regions/micro-regions/AT-02_micro-regions.geojson.json"
response = requests.get(url, timeout=20)
response.raise_for_status()
for region in response.json()["features"][:2]:
    print(region["properties"].get("id"), region["geometry"]["type"])

Test a Useful Signal

Match Avalanche Regions

Inspect two EAWS microregions before joining bulletin coverage.

  1. 01Download one partition and retain its region IDs.
  2. 02Compare a destination coordinate with candidate polygons.
  3. 03Explain why a geometry match is not a current avalanche warning.
