A tiled imagery layer is a type of imagery layer you can host in ArcGIS Online that contains raster data preprocessed and stored as tiles. These tiles are designed for fast rendering in Esri apps such as Map Viewer, Scene Viewer, and ArcGIS Pro. Additional visual rendering, analysis, and other processing tasks can be performed in the app.
You can do the following with tiled imagery layers:
- Access—With a Creator, Professional, or Professional Plus user type and the Publish tiled imagery layers privilege, you can publish a hosted tiled imagery layer in ArcGIS Online. With a Professional or Professional Plus user type and the Imagery Analysis privilege, you can use tiled imagery layers as input to raster analysis tools and raster functions.
Note:
The Publisher, Facilitator, and Administrator default roles include these privileges.
- Publish—You can publish a single image as a tiled imagery layer. If you have multiple images, you can mosaic them into a single dataset as part of the publishing process. Learn how to publish a hosted tiled imagery layer.
- Use—Tiled imagery layers support most common imagery and raster data workflows. With tiled imagery layers, you can do the following:
- Work with pixel data and metadata.
- Perform raster analysis.
- Work with multidimensional data.
- Apply processing templates.
- Share—Hosted tiled imagery layers can be shared with your organization, specific groups, or the public. As the owner of a tiled imagery layer or a member of the administrator role, you can modify its details and change its settings, which will affect how other users can work with that layer.
Tiled imagery layer type attributes
Imagery layers (tiled and dynamic) have type attributes that indicate properties about the layer. You can view an imagery layer's type attributes in the summary section of its item page or in the table of items on the Content page of your organization. The type attribute appears in parentheses next to the imagery layer type.
Tiled imagery layers can have one or more of the following type attributes:
- hosted—Indicates the imagery layer is hosted in your organization.
- multidimensional—Indicates the imagery layer is multidimensional. You can configure its multidimensional settings in Map Viewer.
Note:
Tiled imagery layers cannot have the collection type attribute. Only dynamic imagery layers support image collections.
Layer functionality comparison
Imagery layers (tiled and dynamic) contain raster data and support visualization and analysis. Tiled imagery layers support most common imagery and raster workflows and provide fast rendering and analysis. However, if you are working with multiple datasets or need access to advanced layer settings, a dynamic imagery layer may better meet your requirements.
If you are working with static raster data and require visualization, consider publishing the data as a tile layer (not to be confused with a tiled imagery layer). Tile layers are optimized for fast and scalable visualization workflows that do not include analysis, such as basemap creation.
The following table compares the functionality of tiled imagery layers to dynamic imagery layers and tile layers in ArcGIS Online:
