[Talk-us-massachusetts] Why Barnstable is such a mess, and other MADness (Wayne Emerson, Jr.)

[Yury Yatsynovich]

Hi Wayne,
below are my opinions/responses to your questions

>>> 1. Should we incorporate these MSAG boundaries into OSM as admin level
9
or 10 boundaries?

Not sure. Western Mass doesn't have counties as admin_level 6 because, as
the note says, that "there is effectively no county-level government here".
So, by the same token, those "villages" also barely have administrations, I
guess. Besides, do these villages have officially recognized/recorded
borders that could be imported?
My suggestion would be to include addr:suburb for the cases when two or
more identical addresses exist within a city


>>> 2. While checking the ???Street Name Mismatches??? is there anything we
should do on the google spreadsheet if it seems like the MAD name is wrong?

I was recording what is written on the street sign (column "What is written
on street signs?") and, if OSM is wrong, correcting the street names in
OSM. The cases when MAD is wrong can be corrected automatically before the
import

>>> Many mismatches are just a matter of punctuation

Indeed, it also happens that different spelling can be seen on different
street signs along the same street within the same town. In such cases I
add a note to the Google spreadsheet that both names are possible.
It would be great, if we had lists with official street names to
resolve/automatically correct such spelling/punctuation discrepancies.

>>> 3. Is anyone going to organize notifying each town of address
mismatches?

I was thinking about notifying the tows about all erroneous MAD addresses
(by MAD ids) that we find.


>>> 4. Were the street names in MAD originally in all caps or should we
notify the local assessor???s office if the capitalization is wrong in the
google spreadsheet? i.e.: "J a McDermott Circle" or "Oconnor Drive"

Wrong capitalization of names in the Google Spreadsheet (like "Oconnor
Drive") is a result of my code's' imperfection -- I've been recording such
cases and adding to the dictionary in the code to improve it. But, true,
absence of, say, " ' "- sign (shouldn't it be "O'CONNOR DRIVE" in the
capital case instead of "OCONNOR DRIVE"?) might be worth reporting. But,
again, how do we know that the official street name is not "OCONNOR DRIVE"?

>>> 5. I have also noticed other weirdness such as where the Humarock
section of Scituate uses Marshfield???s Zip code. Do Zip codes matter for
the MAD import?

So far I'm keeping zip codes in the files for import, but not using them
for any matching and, as wiki says, we are probably not allowed to import
zip codes.

>>> 6. While checking the ???Street Name Mismatches??? I kept finding
streets
that were missing from OSM but were not in the spreadsheet. When the
addresses were checked was it looking for missing streets?

The "street names to correct" sheet in the Google Spreadsheet contains only
those OSM streets that have close enough locations and names to MAD
addresses so that one can be sure that the OSM and MAD names belong to the
same street. For all mismatches, please, see the files in the
"addr_problems_after_case_insensitive_matches" in the MEGA/Dropbox folders,
links to which are on https://github.com/yyatsyn/MassGIS-address-import.
After loading those shp-files into JOSM/QGIS one can see where the MAD and
OSM mismatch and whether the OSM/MAD street names should be corrected or
even a missing street should be added to OSM.


>>> 7. When we are done checking the ???Street Name Mismatches??? will the
Street Name check be run again to check for other changes that may have
occurred in the meantime?

Yes, we can do it again later to see the remaining/newly created mismatches.

With kind regards,
Yury Yatsynovich
