I'm a beginner.
ArcGIS Pro provides a wide range of maps/data via its "All Portal". They have a few excellent maps I would like to use.
Is there an equivalent service from within QGIS or do I need to subscribe to ArcGIS to utilise these maps?
NextGIS Web features:
Also you can manage user rights for all you data (layers, maps, services, etc.).
Additionally there is the mobile client for offline work, also integrated with NextGIS Web.
