<div dir="ltr">MassGIS has just replied:<br><br>"<p class="MsoNormal"><span>Yuri: Interesting that you are looking for
this data. Believe it or not, issues and disputes still remain; some get
resolved,
some don’t. The issues with waterway boundaries is that in some places,
over the years, either man or mother nature has changed the course.
Also, the way things were laid out in the past, they followed roads or
railroad right of ways that were subsequently
moved.</span></p>

<p class="MsoNormal"><span>Anyway, the best (and most fascinating) “data” regarding town boundaries is the

Atlases created by the Harbor and Lands Cmsn around 1900. They are the
original statewide surveys of town boundaries. I think that would
have the best representations you are looking for as far as
descriptions; especially if your interest is in a single (or few) spots.</p>

That sounds like good progress in understanding. It might still be good<br>
to ask of massgis when you hear back if that really does mean that if<br>
the river moves the boundary moves.<br>
<br>
The next question is who decides where the river is, and if the intent<br>
is that they update the database. And then if they haven't yet, where<br>
the state government thinks the boundary is.<br>
<br>
I suppose really we need a QA process to basically diff the state layer<br>
against OSM and flag discrepancies for review.<br>
