<div id="yiv713366138">Hi all - <div><br></div><div>We'll have better prep next time, but thanks to Eric Butler & Stefano Costa for joining in a fun conversation.</div><div><br></div><div>Items discussed:</div><div><div>- Introductions & review of interests</div>
<div> -- Stefano is an old-time OSM'er who also works with archaeological efforts in Italy, near the French border</div><div> -- 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</div>
<div><br></div><div>- Discussion of a potential workflow for extracting semantic information from old maps using the OSM infrastructure</div><div> -- In many ways, this is a modification of Brad Thompson's work with <a rel="nofollow" target="_blank" href="http://pastmapper.com/">pastmapper.com</a>: http://blog.pastmapper.com/vectorization/</div>
<div> -- Used Seattle's Pioneer square in 1878 as an example</div><div> -- Extract data for region of interest from modern OSM data using JOSM</div><div> -- Delete everything down to the road grid<br></div><div> -- If possible, warp a map to use as a base layer - see: <a rel="nofollow" target="_blank" href="http://www.mapwarper.net/">www.mapwarper.net</a></div>
<div> -- Trim the street grid down to what existed at the time </div><div> -- Start... artisinally.... building things up from scratch, using whatever sources are available</div><div> -- See: http://i.imgur.com/Mj2nh.jpg</div>
<div> ---- 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</div><div>
---- The roads are from modern OSM, the buildings & other information are hand-added</div><div><br></div><div>- Discussion of need for getting the Rails Port up & running already</div><div> -- I am behind on this, need to get moving</div>
<div> -- Stefano pointed out need for just having something to get started with</div><div> -- Stefano mentioned possible interest in Pleiades import, etc.</div><div><br></div><div>- Once the HO Rails Port is up & running, we could then identify what needs to be fixed to simplify and streamline the workflow</div>
<div><br></div><div>- Stefano: Interest in mapping geographic changes over time</div><div> -- e.g. paths of rivers over 100s of years</div><div><br></div><div>- Eric: Interest in being able to populate map information from geocoded business information, which is good once there are addresses. </div>
<div><br></div><div>- 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?)<br>
<br></div><div>That's about it for now... need to get that Rails Port up and going...</div></div><div><br></div><div>Please send any suggestions or ideas to the list.</div><div><br></div><div>Next hangout: 9 January, 9am Seattle, 5pm London</div>
<div>- I'll market this one a little better & provide more advance notice.</div><div><br></div><div>Links discussed during the call (in chrono order (of course!))</div><div><div><a rel="nofollow" target="_blank" href="http://www.pastmapper.com/">www.pastmapper.com</a></div>
