The practice is to understand the source and how the data was collected. If one has been field surveyed and the other was taken from an USGS quad map, then I would go with the field survey, most of the time. You need to get to the source of the data you are using to make the determination. In the end, they both could be wrong.

Kalasardo Sent: Friday, October 24, 2014 3:59 PM To: [log in to unmask] Subject: NY/CT border dispute Good Afternoon all, When taking data from two different sources, that share a border between them, and you have an overlap, what's the common practice for determining which border on the shared side is the most accurate? I'm asking generally right now, but more information can be given. Thanks, Jennifer M.
