From Source to Product Signal

Test a Product Idea in Four Steps

WFIGS publishes a separate current perimeter layer for agency-reported wildfire footprints. Start with three bounded feature records and keep polygon date and incident name. Perimeters can lag a moving fire and are not evacuation or legal boundary maps.

1

Check the Setup

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

Access the Data

  1. 1.Read the perimeter item's official notice and update context.
  2. 2.Query three current perimeter records from its feature layer.
  3. 3.Inspect polygon date and incident identity before mapping.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import requests

url = ("https://services3.arcgis.com/T4QMspbfLg3qTGWY/arcgis/rest/services/"
       "WFIGS_Interagency_Perimeters_Current/FeatureServer/0/query")
response = requests.get(
    url, params={"where": "attr_IncidentTypeCategory='WF'", "outFields": "OBJECTID,poly_IncidentName,poly_PolygonDateTime",
                 "returnGeometry": "false", "resultRecordCount": 3, "f": "json"}, timeout=30,
)
response.raise_for_status()
for feature in response.json()["features"][:3]:
    row = feature["attributes"]
    print(row["OBJECTID"], row["poly_IncidentName"], row["poly_PolygonDateTime"])

Test a Useful Signal

Inspect Current U.S. Fire Perimeters

Review three reported fire polygons before map rendering.

  1. 01Keep object ID, polygon date, incident association, and attribution.
  2. 02Filter prescribed or superseded features when building a current map.
  3. 03Explain why a perimeter does not establish evacuation status.
