some ideas from Corona Virus "Stay at Home" order

Evidently, some homeowner policy underwriters do want to track the 
geotagging.  I doubt it's for anything legally binding, but may be to 
help with their own statistics for certain range areas.  Perhaps a more 
fine-tuned approach to assess risk than using zip code for instance.

I thought the geocoding for a property might be more readily available 
from some local government database, but I've been told that they would 
only be using a surveying coordinate system.
