The spatial reference of the image tile layers should match the spatial reference of the basemap.

Map tile services

Map tiles are typically retrieved by specifying a specific level, row, and column value.Learn more is a data serviceData services, also known as hosted data services, are services created dynamically to store and provide access to your data in ArcGIS. Examples are feature services, vector tile services, map tile services, image services, and scene services.Learn more that provides static pre-rendered image tiles to display at different scales.

You can use the following kinds of URLs for the source to add services to your ArcGIS Map:

• Item page URL (recommended). This URL points to the specific item page of a service. It provides details about the item, such as metadata, sharing settings, and access options. You can find it by navigating to the item page on ArcGIS Online or in your portal and copying the URL from the browser address bar.
  • Example: https://www.arcgis.com/home/item.html?id=9f86716d941c4410b0b406d911754b2c for items accessible via the ArcGIS Online public URL or https://yourorg.maps.arcgis.com/home/item.html?id=9f86716d941c4410b0b406d911754b2c for items within your organization.
• Services URL. This URL directly points to the REST endpoint of a web service. You can find the service URL by accessing the service item in your portal and copying the URL from the item's details page (usually at the lower right).
  • Example: https://tiles.arcgis.com/tiles/P3ePLMYs2RVChkJx/arcgis/rest/services/Esri_Hydro_Reference_Overlay/MapServer, which is https://yourserver.domain.com/arcgis/rest/services/YourFolder/YourMapService/MapServer
