FWIW geolocation data provided by Google, and perhaps other sources, often includes “GPS” derived geolocations. Google reports those locations as accurate to 2 to 16 meters, i.e., 6.2 to 50 feet.

That fence is almost always larger than the area of interest to ensure that all potential visitors are counted, at the expense of falsely counting some non visitors. For the specific case of True the Vote, a geofence with a radius of 100 feet was used.
