Mike, not at all; I’m taking notes and in the coming weeks we’ll get stuff updated. The link to the DRCOG data is on the wiki, maybe you want to see the converted? Chad can correct me if I’m wrong, but at the moment the converted data is stored locally, maybe we can take a look if you do make it tonight. Otherwise I’ll follow-up with you soon.

I don't think I will be able to make it tonight, but if you provide a link to the original data I could do some work, provide some - hopefully helpful - feedback, and with your OK, help flush out the wiki page. Again, it is great to see this moving forward!

I’m adding Chad here (and dropping talk-us), he can answer more specifics about what we’re doing with the data, but like the ‘other_tag’ we’re using that to further define the building type where we can. You are correct, DRCOG tasked for imagery and digitization of that imagery so they are the owners of the data. =Russ From: Mike Thompson [mailto:miketh...@gmail.com] Sent: Tuesday, January 24, 2017 6:41 PM To: Russell Deffner Cc: OSM US Talk; Imports US Subject: Re: [Imports-us] OSM-Colorado Mappy Hour Denver Buildings Import Discussion The data here: http://gis.drcog.org/datacatalog/content/planimetrics-2014-building-roofprints Doesn't seem to match the description on the wiki. Perhaps it has already been converted partly to the OSM tagging (e.g. sheds and garages are separate)?

Hopefully we can use its success to convince other government bodies in Colorado to allow us to import their data into OSM! Here are a few comments. re: "The Denver Regional Council of Governments (DRCOG), in partnership with local governments and public entities, has purchased detailed infrastructure data..." - This makes it sound like they purchased a commercial dataset, which raises questions about licensing in my mind. I suspect that what happened is they "contracted for the collection of detailed infrastructure data..." In other words, it was work for hire, and they own all rights to the data,. Therefore, as long as the right official within DRCOG signs off, we are good (no third party vendor has any ownership rights in the data and doesn't have to be consulted). If this is in fact the case, someone may wish to change the wording. "Tagging Plans", "OTHER_TAG" - does this contain any useful information we can map to OSM tags? re: "Building Roofprints (poly) - Stereo-compiled (3D)" * Where applicable, are the buildings in the source data orthogonal (square corners) - like we try to create in OSM? * re "multi-level commercial/industrial buildings" I presume this means a building that has multiple roof heights, not multiple levels/floors inside the building. For example a building that has one section that is two stories high and has a roof height of 20 feet, and another section that is three stories high and has a roof height of 30 feet. * re "multi-level commercial/industrial buildings" - consider relations to group the various building parts together. [1] A "parking structure" should probably be tagged: amenity=parking parking=multi-storey [3] (not sure it should get a building tag) A "tank" should probably not be tagged as building=, but rather just man_made=storage_tank [2] Not all "medical" buildings will be hospitals. Nothing is said about how the features other than buildings will be imported. Nothing is said about how the imported data will be conflated with the existing OSM data (I see there is a place holder). re "Merge Colorado Office of Information Technology (OIT) state address layer..." - does this data have a ODbL compatible license?

Last spring the Denver Regional Council of Governments approached our local group, OSM-Colorado <https://www.meetup.com/OSM-Colorado/> , to discuss if and how a ton of planimetric data that they have collected and released as public domain could also be added to OpenStreetMap. Since then we’ve been discussing with the local mappers and working together with DRCOG to prepare a pilot import for their building dataset and we’re very close to that goal. This email is mainly a ‘last call’ for the local/US community to review what we have outlined on the wiki: http://wiki.openstreetmap.org/wiki/Denver_Planimetrics_Import before we send notice to the main imports list. The other thing this email is, and why I’m cross-posting, is because we’d love to have you come discuss the import and other OSM stuff at a Mappy Hour tomorrow the 25th; details: https://www.meetup.com/OSM-Colorado/events/237116910/ Of course if you can’t make mappy hour please email me any comments, thoughts, suggestions or advice; thank you! =Russ Russell Deffner russdeff...@gmail.com _______________________________________________ Imports-us mailing list Imports-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/imports-us
