Hi All,

One other thing I was wondering: on Commons, is there a way to show the collection of bounding boxes on a Wikimap, for a category of images that use the "Map" description template, which can include such information.

What I've got in mind is a category like https://commons.wikimedia.org/wiki/Category:MC_map_migration_test_set all of which's images use the Map template and have bounding box information.

I hoped that this might be displayable via the Template:GeoGroupTemplate at the top of the category page, but no deal.

Ideally, it would be nice to be able to put a template on the top of a category page; pick up the bounding-box information from all of the map descriptions, and display the results on a Wikimap.

This would be particularly useful for examining the contents of categories like https://commons.wikimedia.org/wiki/Category:Goad_fire_insurance_maps_of_Leed...) where the individual maps form part of a systematic arrangement; but it would also be useful for categories of old maps generally.

An earlier method (before the Map template) was to explicitly specify corners for the bounding box, which the GeoGroup template /can/ pick up, as for example for https://commons.wikimedia.org/wiki/Category:Ordnance_Survey_Drawings However, by plotting push-pins rather than bounding boxes, this ends up a rather overcrowded mess, that is difficult to interpret. Bounding boxes would be a lot better, by making it a lot clearer as to which points are linked with which.

Does anybody know if perhaps it is already possible to do this?

Or, alternatively, would creating and adapting templates to achieve this be a lot of work, or should it be relatively straightforward?

Thanks in advance,

Best regards,

James Heald.
