Quick update for those following from home. @bert and others have been going gangbusters pushing this forward, and (I think) it's starting to look really good. A first design was to try to package all the georefencing information in a singe Commons geoshape object, for example this revision <https://commons.wikimedia.org/w/index.php?title=Data:Pigot_and_Co_(1842)_p2.138_-_Map_of_Lancashire.mask.map&oldid=362173957> This was impressive, but it was a bit of a nasty hack, and packaging all of the data up to look like a geoshape creates a data-structure that's pretty unnatural and not immediately inuitive. So a better and more straightforward approach seems to be to create three different objects in the Commons data namespace for each georectification: - A tabular data file containing the georeferencing control points <https://commons.wikimedia.org/wiki/Data:Pigot_and_Co_(1842)_p2.138_-_Map_of_Lancashire.gcps.tab> - A tabular data file containing the pixel coordinates of the boundary of the georeferenced area <https://commons.wikimedia.org/wiki/Data:Pigot_and_Co_(1842)_p2.138_-_Map_of_Lancashire.mask.tab> (the map mask) - A geoshape file representing the mask in latitude and longitude coordinates <https://commons.wikimedia.org/wiki/Data:Pigot_and_Co_(1842)_p2.138_-_Map_of_Lancashire.mask.map> It's now hoped to develop a micro-service that can read these objects and serve a Tiled Map Service (TMS) layer containing the georectified map, with caching for responsiveness. In parallel to this, great progress has been made developing importers to bring in data where there is existing georeferencing for Commons maps on external sites. It should now be possible to import from Commons MapWarper, NYPL MapWarper, BL Georeferencer (Klokan v2), and the David Rumsey collection (Klokan v4). Special MVP award to @thisismattmiller for some of this. Now is a good moment for discussion / consideration / review, but I have to say, myself, I am blown away by how much and how quickly in the last 48 hours people have managed to achieve on this.
