Greg,
What do think about off-loading the data to a .osm file?
When the purpose of the data is determined and the polygons are
geographically correct and a maintenance plan is developed it could be
re-loaded.
Currently the aesthetics stink. Every tiny land parcel boundary is defined.
It's easy to find scores of contiguous parcels that could be grouped into
one.
Why do you suppose that very little land near the Quabbin is tagged
landuse=reservoir_watershed?
Here's the overpass query https://overpass-turbo.eu/s/KHO
MassGIS has a shp file that it doesn't look anything like our data. It
breaks the state up into 32 watersheds
