Imagery & Remote Sensing

What's new in imagery in ArcGIS (June 2024)

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:

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.

Multidimensional imagery layer with non time dimension
Multidimensional imagery layers with multiple non-time dimensions are now supported.

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.

Resample type options
Resampling options are available in the image layer properties.

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.

Image Type Attributes
There is additional information about the imagery layers to indicate if they are collections or 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.

Accessing raster function templates
Raster function template editor can be accessed through the new Raster Function Template section.

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
Accumulated distance was calculated using the Distance Accumulation tool with the Hiking Time Vertical Factor function in the Map Viewer. The results were then used in Optimal Path as Line to derive the optimal hiking paths to and from the campground, and displayed in a Scene Viewer.

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.
