Display map | ArcGIS Maps SDK for Qt

View on GitHub Sample viewer app

Display a map with an imagery basemap.

The map is the fundamental building block of any GIS application and is used to specify how geographic data is organized and communicated to your users.

Run the sample to view the map. Pan and zoom to navigate the map.

1. Create a Map with a basemap using the BasemapStyle::ArcGISImagery BasemapStyle.
2. Create a MapView object to display the map.
3. Set the map to the map view.
