If you only use a <geocode> element in your CAP alerts, then to parse your

Send this data to Google in Esri shapefile format for pre-processing.

If using `\u003cgeocode\u003e`, provide Google with additional data in Esri shapefile format for pre-processing. NOAA's use of the Universal Geographic Code (UGC) in their AWIPS Basemap Shapefiles database is an example. It's crucial to send Google updated geocode files whenever there's a change to maintain accurate alert parsing.\n"]]
