Hi Chris, thanks. The bounding boxes are stored in the "Map" description templates of the individual images on Commons. So for example, go to https://commons.wikimedia.org/wiki/File:Pigot_and_Co_(1842)_p2.042_-_Map_of… and then scroll down. They're not on Wikidata, because individual book illustrations are not notable for Wikidata (at least I don't think so). They're not on OSM, because they relate to the particular map, rather than the feature that's being mapped. So eg different maps of the same town or county may have different bounding boxes, depending on how much of the surroundings are included -- and they may not exactly correspond to any feature at all, eg where multiple map sheets are used to cover a town or a county. What at the moment is possible is for individual /points/ on a map description page to be picked up, and shown on a map for the whole category -- see eg the link at the top right of https://commons.wikimedia.org/wiki/Category:Ordnance_Survey_Drawings So if /points/ can be emitted from description pages and caught by such a template, my question is whether this could be tweaked to allow /box/ coordinates to be emitted and caught in the same way, and then shown on a map by such a template. I've haven't yet delved into the details of how the mechanism to catch and then display /points/ works; but I was hoping there might be people on this list who might know all about it, who could then advise. Thanks again, James. On 11/12/2017 21:59, Chris Koerner wrote: --- This email has been checked for viruses by AVG. http://www.avg.com
