Finding historical maps

User story: I browse a topic page and I wish to find historical maps that depict that place. I would like to overlay the map on the present-day map and see where all the places are located.

Location component

• I will go to the location component. The component initially displays either a pin or an area or both for the page topic. To find and select a historical map overlay, I open the base map menu.
• In the base map menu, there is an option to display a scanned map for this topic's area. I can click to choose which map to display.
• 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 extend the search to maps that have not been georeferenced. The functionality is similar to the independent maps component - how to unite the two?

Maps component

• I navigate to the maps component to see which maps are available for this area.

Controls

• 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
  • Verify that the map depicts the topic. The map is saved to Wikimedia Commons.
  • Confirm that the maps does not depict this topic. The blacklist is saved somewhere, or the image is saved to Commons with the corrected topic.
  • Add to a collection etc.

Actions

• I can georeference un unwarped map in Wikidocumentaries using the Georeferencing tool. 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. The annotation geometries are saved to xxx, and they can be warped along with the map (Allmaps).

Input, output

Source imagery

• 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

Resulting ground control points from georeferencing

• Wikimedia Commons? Allmaps?

Traced geographic shapes with properties

• OSM
• OHM
• Wikimedia Commons
• Allmaps
• Other?

Annotations

Same as above but for images. Wikidata?
