HI Skyler, I'm also a NY mapper, welcome to the party!
You've probably gleaned by now that imports are a touchy subject in OSM. Data license is part of the problem, since only the very most open of open licenses are compatible with OSM. My assumption is that the NYS address data will pass this test, but then there are additional questions of accuracy, transformation, maintainability, and conflation with the existing data. One thing that jumps out right away -- importing addresses for all of NY state is a gargantuan task. Most address imports on OSM will center around a small area, maybe as large as a county, and even so the task will generally be broken up into even smaller areas using a tasking manager and imported gradually by a team, with a lot of manual scrutiny. An address import for all of NY State would likely be a years-long, project. I also expect that data quality, both location and the address fields, will vary in the extreme. There may be some portions of the state where the data is entirely useless, or will do more harm than good. And unfortunately, without local knowledge to consult, it can be difficult to determine this ahead of time. My advice would be to sketch out an import plan for a small community you're familiar with, and see how that goes. You'll probably find that some common assumptions about addresses are false at the edge cases. For instance, you mention deduplicating by searching for existing elements with matching addr:* tags. But I've frequently found a single address applying to several buildings/properties, and the converse too of course. Having different roads with the same name in close proximity is also alarmingly common. Expect mismatches due to variance in street names (Campbel Lane, Camp Bell Road, etc.) or addresses currently mapped with only a housenumber. There are also many areas in NY where we have buildings mapped without address tags. Ideally we'd want to add the address tags to the building where appropriate, rather than just plop a new node somewhere in the building's vicinity. This would almost certainly take a lot of manual tweaking. It's an exciting prospect to have good address data for the large portions of the state that are relatively unmapped. I'll be happy to assist with this project in whatever form it takes. For now I'm still mapping addresses the old-fashioned way, by reading the numbers off of mailboxes and front doors. Good luck, Jason _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
