From Source to Product Signal

Test a Product Idea in Four Steps

The DPC GitHub repository publishes a national criticality bulletin daily and can add corrections. Start with one current today/tomorrow TopoJSON file from the latest bulletin commit. A forecast criticality zone is not a point flood measurement; retain issue and revision context.

1

Check the Setup

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

Access the Data

  1. 1.Read the DPC repository's update schedule and CC BY licence.
  2. 2.Find the latest commit touching the topojson bulletin directory.
  3. 3.Fetch one current bulletin file from that exact commit.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import re
import requests

repo = "https://api.github.com/repos/pcm-dpc/DPC-Bollettini-Criticita-Idrogeologica-Idraulica"
headers = {"User-Agent": "TrilemmaDataCatalogExample/1.0"}
commits = requests.get(f"{repo}/commits", params={"path": "files/topojson", "per_page": 1},
                       headers=headers, timeout=30)
commits.raise_for_status()
sha = commits.json()[0]["sha"]
detail = requests.get(f"{repo}/commits/{sha}", headers=headers, timeout=30)
detail.raise_for_status()
files = [item["filename"] for item in detail.json()["files"]
         if item["status"] != "removed" and re.fullmatch(
             r"files/topojson/\d{8}_\d{4}_(today|tomorrow)\.json", item["filename"])]
if not files:
    raise RuntimeError("Latest bulletin commit has no current TopoJSON file")
url = f"https://raw.githubusercontent.com/pcm-dpc/DPC-Bollettini-Criticita-Idrogeologica-Idraulica/{sha}/{files[0]}"
bulletin = requests.get(url, timeout=30)
bulletin.raise_for_status()
print(files[0], list(bulletin.json().get("objects", {}))[:5])

Test a Useful Signal

Inspect One Italian Criticality Bulletin

Check one official daily zone artifact before local hazard matching.

  1. 01Retain commit SHA, bulletin filename, publication date, and zone IDs.
  2. 02Prefer later corrections to earlier files for the same validity day.
  3. 03Explain why forecast zones do not confirm a flood at a destination.
