[Historic] December Historical OSM Hangout Notes

[Mikel Maron]

Right on. Sorry to miss this one. (Going to miss the next one too, travelling that day).

For the rails port, if having a server is a stumbling block, I can offer up space on GroundTruth's dedicated server.

>Hi all - 
>
>
>We'll have better prep next time, but thanks to Eric Butler & Stefano Costa for joining in a fun conversation.
>
>
>Items discussed:
>- Introductions & review of interests
>  -- Stefano is an old-time OSM'er who also works with archaeological efforts in Italy, near the French border
>  -- Eric is here in Seattle and cannot remember what was in that empty retail space he passes on the street & wants to work backward as far as he can, using the extant OSM database as a starting point
>
>
>- Discussion of a potential workflow for extracting semantic information from old maps using the OSM infrastructure
>  -- In many ways, this is a modification of Brad Thompson's work with pastmapper.com:  http://blog.pastmapper.com/vectorization/
>  -- Used Seattle's Pioneer square in 1878 as an example
>  -- Extract data for region of interest from modern OSM data using JOSM
>  -- Delete everything down to the road grid
>
>  -- If possible, warp a map to use as a base layer - see: www.mapwarper.net
>  -- Trim the street grid down to what existed at the time  
>  -- Start... artisinally.... building things up from scratch, using whatever sources are available
>  -- See:  http://i.imgur.com/Mj2nh.jpg
>      ---- Clearly, this is overtagged & many of these tags belong in other systems, e.g. linked Historical Business Directories or People Directories or image databases, but it's stored here for now
>      ---- The roads are from modern OSM, the buildings & other information are hand-added
>
>
>- Discussion of need for getting the Rails Port up & running already
>  -- I am behind on this, need to get moving
>  -- Stefano pointed out need for just having something to get started with
>  -- Stefano mentioned possible interest in Pleiades import, etc.
>
>
>- Once the HO Rails Port is up & running, we could then identify what needs to be fixed to simplify and streamline the workflow
>
>
>- Stefano: Interest in mapping geographic changes over time
>  -- e.g. paths of rivers over 100s of years
>
>
>- Eric: Interest in being able to populate map information from geocoded business information, which is good once there are addresses. 
>
>
>- Jeff: I'd like to see greater International participation in the brainstorming for this effort, so that we're all more aware of various related efforts around the world & to make sure we're putting enough global perspective into our planning. (Is there ever too much?)
>
>
>That's about it for now... need to get that Rails Port up and going...
>
>
>Please send any suggestions or ideas to the list.
>
>
>Next hangout: 9 January, 9am Seattle, 5pm London
>- I'll market this one a little better & provide more advance notice.
>

>Links discussed during the call (in chrono order (of course!))
