Imagery can be hosted, visualized, analyzed, and shared in ArcGIS Online, which assists organizations in managing and sharing their imagery data without the need for infrastructure. Once you have all your imagery data organized, ArcGIS Online allows for analysis workflows, including deep learning. For this release, the licensing model has been updated to allow you to access imagery hosting and analyzing capabilities, enhanced user experience to access and manage raster function templates for analysis, improved the identification of imagery layer items has been improved, and new options were added for raster tools to complete your work.
Licensing model change for ArcGIS Image for ArcGIS Online
Previously the ability to host imagery layers and access raster analysis tools and functions required the ArcGIS Image for ArcGIS Online user type extension. Now the imagery hosting, and raster analysis capabilities will be folded into the following user types in ArcGIS Online:
- Creator or Professional or Professional Plus will allow you to create hosted imagery layers.
- Professional or Professional Plus will allow you to perform image analysis.

Improved support for configuring multidimensional imagery layers
ArcGIS Online Map Viewer includes improved support for multidimensional imagery layers. You can now configure multidimensional imagery layers with multiple non-time dimensions. The dimension slider can be used to animate slices along each non-time dimension.
Resampling
In Map Viewer from the image layer properties, you can now resample your imagery layer to control the visualization of your imagery layer. Choose the resampling option that creates the desired visualization for your imagery layer.
Identify imagery layers by type attributes
Imagery layer items now include text to indicate whether the imagery layer has a collection or multidimensional type attributes. Now you can see additional information about the imagery layers in your organization. You can see whether the dynamic imagery layer has a collection and also identify whether the imagery layer is multidimensional.
Raster function template editing
The Raster Function Templates tab is now available in the Analysis pane, providing access to the Raster Function Editor to create or modify raster function templates. Previously, you could open a new raster function template from the bottom of the Raster Functions tab. Now you can access the Raster Function Editor directly from the Raster Function Templates tab to create, edit, and manage your raster function templates for analysis.
List of raster function templates
You can save a list of raster function templates that you have worked on within the web map. As you open raster function templates from the Raster Function Template tab, each of those raster function templates will be added to the list for you to use again or share with others. The list is saved in the web map and will be there to be applied to other imagery layers.
Raster tools and raster functions
There are new parameter options added to existing raster tools and raster functions to augment your workflows. The improvements are as follows:
- Distance Accumulation and Distance Allocation have two new options for the Vertical factor parameter: Hiking time and Bidirectional hiking time. The performance of these tools has also been improved if the Distance method parameter value is Geodesic, or if the Vertical factor or Horizontal factor parameters are set.
- Pansharpen – The Pansharpening Type sets Gran-Schmidt and the sensor list now includes Landsat 9 and Vision-1.
- Unit conversion – SAR units of Amplitude, Amplitude dB, Intensity and Intensity dB are now included as accepted units.
- Remap – the parameter for Change missing values to NoData has been renamed to Change Unmatched values to NoData.
- Zonal Statistics has four new options for the Statistics type parameter: Majority count, Majority percentage, Minority count, and Minority percentage.
- Zonal Statistics as Table has six new options for the Statistics type parameter: Majority count; Majority percentage; Majority value, count, and percentage; Minority count; Minority percentage; and Minority value, count, and percentage.
The Aggregate Multidimensional raster function has been added to Map Viewer, so now all the raster functions from Map Viewer Classic are available in Map Viewer.
