hosted image tile layer
A hosted image tile layer is a hosted layer (item) in a portal that is used to manage the properties and settings of an image tile service. It is accessible through an item page which is used to manage the layer's properties and capabilities. Hosted image tile layers are used to manage and access image tiles. A hosted image tile layer is typically created by using data management tools to create (publish) them from existing hosted feature layers. Client applications can access image tile data through a hosted image tile layer and display the data in maps and scenes.
