I'm looking forward to get deeper with QGIS ATLAS Composer features like we do with some reporting sofwares.
Today I try to map and iterate over parcels and display buildings attributes on the side, all buildings on a slide should be on the iterated parcel.
The idea behind could be more a generic approach to list joint subfeatures from an iterated one used for the Atlas.
For my Use case: Buildings and parcels have a geographical link and also keys to link each other.
Update : I add a better example to be more explicit. In this configuration, we could add buildings linked pictures (from the database urls using html), and so on...
