Is it possible to show the attribution of a layer in QGIS print composer?

Question

I'm working with QGIS 3.22.10-Białowieża. In my project, I'm using the ESRI Satellite tile basemap (through Quick Map Services plugin), which I would like to credit in the map.

I've seen nothing about attribution among the variables section of the map and I can't find anything useful through a Google search. Is it possible to automate that?

Answer 1

You can use layer_property('layername','attribution'). Use it together with array_to_string(layer_property('layername','attribution')) to display the array as string. But: Not all layers provide this. Seems like ESRI Satellite does not. But for example OpenStreetMap does.

Properties you can use (from the docs):

• name: layer name
• id: layer ID
• title: metadata title string
• abstract: metadata abstract string
• keywords: metadata keywords
• data_url: metadata URL
• attribution: metadata attribution string
• attribution_url: metadata attribution URL
• source: layer source
• min_scale: minimum display scale for layer
• max_scale: maximum display scale for layer
• is_editable: if layer is in edit mode
• crs: layer CRS
• crs_definition: layer CRS full definition
• crs_description: layer CRS description
• extent: layer extent (as a geometry object)
• distance_units: layer distance units
• type: layer type, e.g., Vector or Raster
• storage_type: storage format (vector layers only)
• geometry_type: geometry type, e.g., Point (vector layers only)
• feature_count: approximate feature count for layer (vector layers only)
• path: File path to the layer data source. Only available for file based layers.
