Historical map

This page records ideas for workflows to work with scanned, historical maps.

Displaying the place in the location component

See the page about Maps.

I browse a topic page and I wish to find historical maps that depict that place.

I will go to the location component. The component initially displays either a pin or an area or both for the item. To select find and select a historical map overlay, I select the base map menu.
In the base map menu, there is an option to select a scanned map for this topic's area.
In the dialogue that opens, I can select any of the maps that has been georeferenced for this area. I can filter and facet the selection based on depicted time, map scale and possibly other properties.
I can expand the search to maps that have not been georeferenced. The functionality is similar to the maps component - how to unite the two?

I navigate to the maps component to see which maps are available for this area.
The maps are read from several sources. The list will be maintained in APIs page.
- Image files from all the image sources connected to Wikidocumentaries, filtered by type map.
- Georeferenced maps from tile servers.
- Maps from IIIF servers serving old maps

I can facet the maps based on several criteria
- Warped / unwarped
- Timeframe
- Scale
- TBD
I can do the same actions as for images after saving to Wikimedia Commons: confirm the topic / remove from the topic, add to a collection etc.

I can georeference un unwarped map in Wikidocumentaries using the Georeferencing tool (Allmaps). The image is first saved into Wikimedia Commons, if not already there. How will it be made available for IIIF?
I can annotate items on the unwarped map using an annotation interface. (Can this be the same as for images?) The annotation geometries are saved to xxx, and they can be warped along with the map (Allmaps).
