ArcGIS Earth FossWarn alert displayer.

A Python application that harvests Common Alerting Protocol (CAP) data from alerts.kde.org, processes it into a localized memory cache + disk storage, and streams custom KML files to ArcGIS Earth.

(Vibecoded script)

Requirements

• The script uses quite a bit of RAM. (approx 1.3~GB)
• Just make sure your computer has enough RAM if you want to load all alerts into ArcGIS Earth.
