[Talk-us-massachusetts] MassGIS address import -- on duplicates and weird housenumbers

[Alan & Ruth Bragg]

Yuri,
Great work, I agree and am fine with rolling up stacked unit numbers into a
list addr:unit=A;B;C
I've looked at a couple pages on syntax and think the proper delimiter
might be a semi-colon. Maybe someone knows better.
I don't think the quotes are necessary.

There are already 35 buildings in MA with an address of 0. It's certainly
suspicious. I'm in favor of not importing zeros. Import the addr:street etc
but not the addr:housenumber=0
There are two locations with the 0 address in Bedford.

My town gis map shows a building at 32 YD Road that's identified as 0 YD
Road in the massgis point data file.

The other location with an address of 0 is in a stack of 110 nodes
containing 77 different addresses  next to a road on Hanscom AFB. The
POINT_TYPE is BMP.  BMP is noted in the massgis definitions as "oddly
distributed buildings or unusually configured property boundaries ....we
will consider shifting these points to more intuitive and suitable
locations"
