This dialog allows you to specify the location that a given piece of media was created at (See: Media Properties). Locations can be selected by enterering positional coordinates (longitude and latitude), selecing a point on an interactive map, searching the name of a location, or any combination of the three.
The location select dialog. The user has searched and selected the city of San Fransisco.
The location can be cleared by selecing the 'Clear' button at the bottom of the dialog. This will remove the location information from the media. This is different from giving the media a position of 0°, 0°.
To select a location via latitude and longitude, enter the desired coordinates in the boxes labled 'Selection'. The first box represents the latitude and the second in the longitude. Negative and positive numbers are used in place of the standard '°E', '°N', '°S', and '°W'.
The map can be interacted with using the mouse. Clicking on a location will select that location. Clicking and dragging the map will move the currently viewed area, but will not change the selection. Using the scroll wheel will zoom in and out. The zoom can also be changed using the 'Zoom' field under the map. The zoom is represented by an integer value from 1 to 20, with 20 being the most zoomed in.
Entering the name of a location, such as a home address, or a point of interest, such as a city, will center the map on that location and then select it. This process, known as reverse geoencoding, is done by OpenStreetMap's Nominatim API. More information can be found at https://wiki.openstreetmap.org/wiki/Nominatim.
