==Location module==
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.

'''Location module''' is the main map for a topic. It displays the location of the topic. Additionally, it can be made to display much more information. The location data is currently dispersed between several components: a main map (displaying the coordinate location and shape, if available), Location (displaying subdivisions, neighbouring items, and items that the topic is situated or part of), Locations (items that have been declared being situated within the topic), and additional overlap with components Parts and Part of. Ideally, all of these would be displayed in a single display with facets for the information.

===Initial display===
+
3 modules that could be merged
* Display the topic on the map as a pin and/or an area depending on data
+
* Location (gallery of subdivisions, neighbours, and enclosing items)
** Zoom extent to be figured out for a single pin
+
* Location on map (simple pin/shape display)
 +
* In this location (items found within this item, based on semantic definition)
 +

== Location data ==
====Menu controls====
 
* 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.

=== Configurable external sources ===
Data can be read from external sources and displayed on the map.
+
It could be possible to display a geographic dataset from an external source.
* The user can validate these items, and the data can be written to Wikimedia projects or OpenStreetMap.
+
* The data could be used to validate location data on Wikidata. The user could compare existing data to the authority dataset, and make changes to Wikidata accordingly.

There are several ways in which maps can be used.


Location module

Location module is the main map for a topic. It displays the location of the topic. Additionally, it can be made to display much more information. The location data is currently dispersed between several components: a main map (displaying the coordinate location and shape, if available), Location (displaying subdivisions, neighbouring items, and items that the topic is situated or part of), Locations (items that have been declared being situated within the topic), and additional overlap with components Parts and Part of. Ideally, all of these would be displayed in a single display with facets for the information.

3 modules that could be merged

  • Location (gallery of subdivisions, neighbours, and enclosing items)
  • Location on map (simple pin/shape display)
  • In this location (items found within this item, based on semantic definition)

Inthislocation.png

Location data

Topic's location

  • The coordinate point is read from Wikidata. Display a pin for the best rank coordinates in Wikidata.
  • The shape is read from OSM based on a Wikidata tag in OSM. (Add details about this)

Location and shapes of historical elements

OpenStreetMap only stores items that can be verified on the ground. There are different alternatives for shapes of historical items.

  • Historical shapes could be stored in OpenHistoricalMap using the same technology as for OSM.
  • Also shapes stored as .map files in Wikimedia Commons should be displayed
  • Additional technologies can be added.

Hierarchically related items in Wikidata

Geographically associated items in Wikidata

  • Items within the area
  • Nearby items

Images

  • About the topic
  • Nearby images
  • Display a filtered selection of images on the map. Filtering could be made in the images component.

Related items from other components

Filter and facet items in the original component before sending to the map. In the map component only visibility is managed. For example

  • Related people
  • Affiliations
  • Similar items etc.

Configurable external sources

It could be possible to display a geographic dataset from an external source.

  • The data could be used to validate location data on Wikidata. The user could compare existing data to the authority dataset, and make changes to Wikidata accordingly.
  • The style of these elements should differ from items already in Wikidata, and change after validation.
  • The source of the data could be automatically appended to the Wikidata entry.

Data display

  • Pin
  • Shape
  • Popup – Clicking the pin or the shape opens a popup, which links to the topic's page.
  • Image pin
    • Single images in their individual pins/popups
    • Topic's images are collated to the topic popup (if possible). 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.
  • Routes
  • Advanced: Combine several views in one: Map, timeline and gallery.

User actions

  • Facet/filter by data item type. For items from other components filtering takes place in the original component. (TBD)
  • Correct the location of the topic's pin
  • Import new items to Wikidata / enrich existing items
  • View an external dataset on the map.
  • Export map
  • Save map configuration
  • Use the selection for a wikidocumentary

Basemap layers

See also Phabricator task https://phabricator.wikimedia.org/T261569.

Allow several layers that can be stacked and configured. Each layer displays one map.

  1. Base map
  2. Terrain
  3. Orthophoto
  4. Scanned or historical map

Menu controls

  • Transparency slider for each layer
  • Toggle visibility
  • Configuration button opens content selection modal (TBD).
  • Layers can be rearranged
  • Bottom layer is opaque or there is a (chosen?) background colour)

Data display

  • Display map metadata

Content selection modal

Display the most suitable maps based on scale, topic date and availability. Allow to expand to other sources.

Sources Controls Actions
Base map Default map: Styled OSM map.
Available local and international map services, use data collected in OSM
Select / deselect Allow editing the style?
Terrain Available local and international map services, use data collected in OSM Select / deselect
Orthophoto Available local and international map services, use data collected in OSM Select / deselect
Scanned or historical map Display a selection of maps from connected sources
TODO: Create a register of map source APIs
Select / deselect
Filter / facet / sort by scale, date
Allow reading any publicly available raster layer
Georeference
Trace


See also Content modules for a table of all modules.

Map display option for any component

Map display option for any module in addition to gallery, list and timeline.

  • Option in the display menu of items that have geolocation data

Phabricator:https://phabricator.wikimedia.org/T261566

Display formats

  • Usually several disconnected points
    • Aggregates for multiple points
  • Series of points connected to each other with arcs
    • lifeline (start–end) arcs
  • Series of points connected to each other by a line
    • For routes
  • Areas
    • (Historical) geographic subdivisions in a map
    • Cemetery or allotment garden map
  • Temporal aspect if present in the data
    • For life arcs, the color of the arc
    • Animation

Actions

  • Facet items on the map based on their properties
  • Add all or a faceted selection to the topic's map

Map-based search

See Search page

Map-based wikidocumentary

See wikidocumentary

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.
