There are several ways in which maps can be used.
- Map component for a single topic displays everything the user collates together on the map
- Map display option for any component in addition to a gallery and a list.
- Map-based wikidocumentary
- For a given topic, displayed in the header section. There may be several header images of wikidocumentaries per topic, which will then be put on a playlist.
- A wikidocumentary usually touches on many topics, and there must be a topic-independent place for displaying them and a way to find them.
- Map-based discovery interface on the top level.
- Location display in each media metadata view.
- Map-based tools
- 1 Map component
- 2 Map display option

- 4 Map-based search interface
- 5 Location display in each media metadata view

- 7 Navigation
The map component for a single topic displays everything the user collates together on the map. It is possible to display the filtered information from each of the topic page's sections, define their display properties, and add several base map layers. It will also be possible to configure other external data elements to be displayed on the map. Ideally, the map can be exported and embedded elsewhere.
- Display the topic on the map as a pin and/or an area depending on data
- Zoom extent to be figured out for a single pin
- Transparency slider for each layer
- Toggle visibility
- Configuration button opens configuration modal (TBD). Each layer has one map initially.
- Layers can be rearranged
- Bottom layer is opaque or there is a (chosen?) background colour)
The goal is to display the most suitable maps based on scale and topic date by default.

Allow 4 layers that can be configured
- Base map
- Default map: Styled OSM map. Allow changing the style?
- Available local map services, use data collected in OSM
- International services
- Local providers
- Scanned / historical map
- Always best suggestion based on time and scale
- Select/search from available maps in registered sources, including Wikimaps Warper.
- A modal to configure the sources.
- Can display previews of available imagery or data for each layer individually.
- Allows reading any publicly available raster or data layer to Wikidocumentaries.
Pins and popups
- A topic is displayed as a pin. Possibility of correcting the location?
- A topic may also be displayed as a shape from OSM.
- Clicking the pin or the shape opens a popup, which links to the topic's page.
- Topic's images are collated to the topic popup. Each image links to the image viewer
- If there are too many items or images in the area, they will be styled as aggregate.
- Timeline arc for items with several points on a timeline.
- If possible to distinguish routes, they will be displayed without arcs.
- Nearby items are displayed as pins and/or shapes depending on data. Explore the use of images and titles.
- Nearby images have image display. Will it be an opened popup or another way of displaying?
- Clicking on the image pin opens a popup. The popup links to the image viewer.
Data from other components
These could be sent from the component where selecting and faceting can be done with the tools suitable for that dataset.
- Images: Display all related images, a filtered subset or a selection of images on the map
- Other components: Filter and facet items before sending to the map. The relevant tools are present at the original component.
Data from external sources
Data can be read from external sources and displayed on the map.
- The user can validate these items, and the data can be written to Wikimedia projects or OpenStreetMap.
- The style of these elements should differ from items already in Wikidata, and change after validation.
- The source of the data can be automatically appended.
Define more display modes
- Combine several views in one: Map, timeline and gallery.
- Import data source
- Export map
- Save map configuration
- Select map language: Display vernacular/old toponyms?
- Select map style
Map display option
Map display option for any component in addition to gallery, list and timeline.
- Option in the display menu of items that have geolocation data
- Single point, lifeline (start–end) arcs, routes, aggregates for multiple points
- Temporal aspect if present in the data
- Facet items on the map based on their properties
- Add all or a faceted selection to the topic's map
Map-based search interface
- Display items in the given area
- Combine with other search criteria
- Search location by place name. Aim to include historical toponyms.
- Search page design needed. Also useful for displaying scope for shape expressions.
Location display in each media metadata view
- Each image has a small map in the metadata section. This, too, needs to have the same features as maps throughout the site.
- Geolocating tool for images
- Rectifying maps
