Quick update: The import is finished! I've been doing some QC and it really
is great to look at, and so useful. OSM in Baltimore County has better
addresses than any of the other online maps. Hooray for open source!

I'll write a diary post soon detailing some of the ins and outs of this. It
was really fun.

> Greetings Fellow Mappers,
> As some of you may know, I am a GIS Specialist for Baltimore County, Md.
> Since we released our data as public domain around a year ago, I've been
> meaning to do this import. This week I had some free time and decided to
> kick it off, just in time for the 10th anniversary of OpenStreetMap.
> I've been working on this project in the open, as much as possible: at
> https://github.com/baltimorecounty/openstreetmap
> The details of the import procedures are found on the github wiki, which I
> will move to the OSM wiki periodically:
> https://github.com/baltimorecounty/openstreetmap/wiki/Buildings-and-Addresses-Import
> The intent of this import is to provide OSM users with the best and most
> accurate street and building data my office has to offer. Our data is
> thoroughly vetted, verified, and tested. It has to be good, because County
> emergency staff rely on it in the field.
> While preparing the data for import and consideration by the community,
> much thought was put into the content, spatially and in data terms. For
> instance, county address data is stored in all caps, with standard
> abbreviations. The road names' case was changed intelligently, so that
> roads like "McDonough" would read correctly. Also, all abbreviations were
> expanded. More details on the wiki.
> (A note on abbreviations given the recent discussions on various OSM
> mailing lists. Baltimore County is meticulous and methodical about using
> abbreviations in its data. Words like Mount and Saint are never
> abbreviated. Only directionals (pre + post) and types are abbreviated. This
> made expansion a breeze.)
> Please review the wiki and github. Data is on Microsoft OneDrive

> I welcome all feedback, and while I've tried to get it right the first
> time, there may be room for improvement.
> Thanks,
