Change the basemap style

Learn how to change the static basemap tiles style.

The ArcGIS Static Basemap Tiles serviceThe ArcGIS Static Basemap Tiles service, also known as the Static Basemap Tiles service, is a location service that provides basemap data as pre-rendered and pre-styled map tiles for the world. It supports key styles in the ArcGIS Basemap style family. An ArcGIS Location Platform account is required to use the services.Learn more provides access to raster basemap tiles for the world. The service supports a number of ArcGIS styles such as navigation, streets, outdoor, and light-gray. The tiles are returned as PNG files.

In this tutorial, you use the dropdown menu to toggle between the different static basemap tiles.
