Use case

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.

How to use the sample

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

How it works

  1. Create an ArcGISMap with a topographic basemap and an initial viewpoint.
  2. Create a MapView object to display the map.
  3. Set the map to the map view with MapView.setMap(map).

Relevant API

  • ArcGISMap
  • BasemapStyle
  • MapView
