[aprssig] Using NWS County shapefiles for other packets

Is there a mechanism to use the shapefiles that encompass counties for
anything other than an NWS packet?

Here is an example that will display a FLOOD symbol inside two counties
along with county outlines



After studying the details and documents for this packet (Thanks WE7U!), I
am curious if other data could be displayed.


Is the packet type generic enough?

Can "NWS_ADVIS" be anything else?

I am not sure what determines the FLOOD symbol. Is it the product code of
"FLS" or "FLOOD"? 


A current scenario might be COVID-19 cases in a county, but that is only one


Just thinking about current world events and APRS.


I know the NWS is US based. Are other shapefiles available for counties,
states, provinces, etc.?


I hope everyone is being careful and rides out this storm successfully!


Best regards,

Fred N7FMH
