It the world of GIS (Geographic Information Systems) there is a technology called "Geocoding".
Geocoding is converting an address like "123 Main Street, Anywhere, USA" to an Latitude/Longitude coordinate. That's how map directions are created like in MapQuest or Google Maps.
The problem with Geocoding is it isn't perfect. It can make mistakes or not work at all if the underlying data is old or inaccurate. So they are GPS'ing the locations of front doors and additional "dwellings" to fill in the mistakes on test their system for accuracy.
I work in the field of GIS and I assure you, if you are worried about them GPS'ing your front door, you would soil your shorts about how else they can track you (cell phone just for starters...).
This GIS technology is only going to get more sophisticated as every decade passes. I predict that in 20 years we will all be so comprehensively tracked that they will no longer need to hold a "census" - they will already know everything about you in real-time.

this thing about marking, and many of the articles i've read describe it as painting the door. Is this an actual mark of some sort placed on the structure? My understanding of gps is that it's just long/lat coordinates but this sounds like it is a mark that can be read by someone else. so is it something that can be read by some other instrument?
