[Historic] December Historical OSM Hangout Notes

Jeff

What are you using to serve tiles? mod_tile?

I wouldn't worry about restricting tile rendering, at least now as a blocker. Unlikely anyone would browse enough to fill up significant disk. And can simply monitor disk usage, if it starts to creep up, just dump the tile cache.

If we set up a tile server as part of the sandbox, I'd like to limit tile rendering at low zoom levels (say 15+) to selected bboxes, but need to figure out a way of doing this. Otherwise, I could end up owning a RAID array before I know it! : )

>>>- 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

>>>
>>>- Eric: Interest in being able to populate map information from geocoded business information, which is good once there are addresses.

>>>
