An image tile layer is a data layer that can access and display image tile data provided by an image tile service or an image tile package.
The spatial reference of the image tile layers should match the spatial reference of the basemap.
Image tile services
An image tile service is a data service 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 image tile services to your ArcGIS Map:
- Item page URL
- Image tile service URL
You can learn more about image tile services in the Mapping APIs and location services guide.
Local image tile packages
Image tile layers can also access data from image tile packages stored locally.
An image tile package is a single .tpk (or .tpkx) file containing image tiles, and you can share the file as you would with any file. Compared with .tpk files, .tpkx files provide better performance on network shares and cloud store directories.
