Comment from gdt
I'm curious if you are local to Stow/Maynard. I would also like to know when you used the survey points data, if you transformed the points (in NAD83(2011) to some approximation of WGS84. They are really not equivalent, but much software wrongly assumes a null transform. I have been using ITF2014 as a proxy for the current WGS84. I have also been making RTK GNSS measurement of the boundary markers, although those have come out very close to the survey points data that I have deferred to the survey points.
I will be making an adjustment pass at some point to align Stow's points with the properly transformed towns survey dataset points, if I haven't already.

Also I should have said that I'm adding historic=boundary stone for markers that do exist, and those I am putting at my observed coordinates.
