Sorry I missed talking to Matthew at the conference.

Picking just one of the sample file I noticed that the street address is
abbreviated and no tag addr:city.

NE 18th Avenue should be Northeast 18th Avenue

Another sample I noticed that a building outline was made of of two
polygons with two different objectids. See objectid 75375 and 54910
in mia_building_1541.osm. It didn't appear that any of the buildings had

I'd recommend not doing a scripted upload instead break the data into small
chunks for use in Tasking Manager. It means you'll have to spend more time
recruiting new mappers, but it will be well worth the effort.

Good luck with the plan,

> Hi,
> We're proposing a building import for Miami-Date County, FL. Data is in the
> public domain [1]. The initiative was started off with a Maptime Miami
> Meetup event in May by Matthew Toro [2]. There seem to be an interest from
> the community. The dataset contains ~100k buildings (called large building
> footprints) throughout the county with height information. Currently, there
> are ~15k buildings in OSM for the same extent so it will be a huge
> improvement. An Address dataset also exists in the public domain [3].
> Local community is extremely small here compared to other places like NYC
> or LA, so we are planning to import most of the buildings via a script. For
> this, we are checking for potential conflicts. We are not going to upload
> buildings
> - overlapping with existing OSM buildings
> - overlapping with highway/railway=*
> - in the proximity of existing OSM addresses
> We checked for 1-1 relations between the Buildings and Address datasets and
> assigned addresses for buildings in the bulk process. We ended up having
> ~85k buildings in the automatic bucket which leaves ~10k buildings for
> manual review.
> Manual review by the community will be organized through Task Manager jobs
> based on US Census Block Groups. We are hoping that this import task will
> be the kick start of a growing OSM community in South Florida.
> Matthew will be at SOTMUS in Seattle and will talk about this import [4].
> The next MaptimeMIA meetup is scheduled on August 1 [5] where we can
> provide an update on the current state to the local community, and
> (hopefully) we can also start presenting the steps required for the manual
> import process.
> The Wiki page [6] and the technical documentation [7] are yet to be updated
> but our workflow is ready for testing. We are planning to start the whole
> process soon. More updates to come.
> Please feel free to provide any feedback you might have. Hit us up with any
> questions/comments or open an issue on GitHub [7].
