Locations are geographic features on a layer which can be interacted with. An optional query ID (qID) field must be set in the layer definition in order to select locations. Only MVT, Cluster, and GeoJSON layer can have locations.
An infoJ field array describes the location properties and whether these can be edited.
The infoJ is used to query as well as calculate property values from the XYZ backend.
infoJ entries and their values are presented in the info panel of a location.
