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

[Angela Morley]

There are a couple addresses I know of that are properly addr:housenumber=0, including 0 Broadway Lawrence (Kelley furniture). There's so few of them, though, that they can be manually fixed after such an import.

(a relatively small extra step which can be implemented with a script).

I also used a python module titlecase + some patterns that I've noticed in names of streets in MA from OSM (so, there should be no problems with either "McDonald" or "YMCA Street"). Folder with matched and unmatched addresses split by counties is here: https://mega.nz/#F!Wg9RQJzL!MIyYl9kq5AivIm5SOxGAow
