General
ArcGIS Excalibur is a web-based application that modernizes and enhances image and video-based workflows through intuitive experiences. These experiences allow you to search for, discover, and work with imagery in fully integrated workflows.
For more information, see What is ArcGIS Excalibur.
ArcGIS Excalibur is delivered with ArcGIS Enterprise and ArcGIS Online as an embedded application and is accessed through the App Launcher 
for a user with the correct user type licensing. The ArcGIS Enterprise base deployment can, optionally, include ArcGIS Image Server and ArcGIS Video Server to use full imagery and video capabilities.
Different versions of ArcGIS Excalibur work with different ArcGIS Enterprise versions. The following table shows the compatible versions:
| Active portal | ArcGIS Enterprise 12.0 | ArcGIS Enterprise 11.5 | ArcGIS Enterprise 11.4 |
|---|---|---|---|
ArcGIS Excalibur 12.0 |
Embedded application | ||
ArcGIS Excalibur 4.2 |
Embedded application | ||
ArcGIS Excalibur 4.1 |
Embedded application | ||
ArcGIS Excalibur 4.0 |
Embedded application |
For more information about hardware and software requirements, see ArcGIS Excalibur system requirements.
You must have a Creator, Professional, or Professional Plus user type before ArcGIS Excalibur will be available in the App Launcher . To use server-side analysis, the Imagery Analysis privilege must also be enabled with the Professional or Professional Plus user type. For more information about licensing requirements, see ArcGIS Excalibur system requirements.
No. Anyone who wants to discover, analyze, report, and disseminate image and video-derived information to consumers can use ArcGIS Excalibur. Users include all-source analysts, imagery analysts, and imagery and geospatial managers in industries such as national security, emergency response, local and federal government, humanitarian relief, and public works.
You must have your environment properly configured and the proper privileges to publish hosted web layers. If you have the proper environment and privileges, you can begin publishing hosted web layers by accessing them through the home page or at any time on the side navigation menu under Publish Layer. For more information, see Publish hosted web layers.
Use the application
You can obtain a web service URL through any of the following:
- The Content tab of your Enterprise portal—You can search My Content or My Organization's Content for the layer type imagery layer.
- ArcGIS REST Services directory (for example, https://<host.domain.com>/<webadaptor>/rest/services)—Many services defined as an ArcGIS Image Server Service denoted by (ImageServer) can be a supported service.
- Your organization's GIS administrator
For more information about using imagery web service URLs, see Explore a web service.
Ensure that the Filters option and map extent are set to properties and a location where imagery exists for the selected layer.
To populate the Search and Discover page with imagery or video, browse for imagery or video.
Image focus view is available on images that have sensor transformation information, such as rational polynomial coefficients (RPC) or frame cameras. Not all web services contain imagery with this sensor information.
For more information about the image focus view, see Explore a web service.
The Measure tool dynamically reads in the metadata and capabilities set on the image service. The measurement options available depend on the imagery service layer you are working with.
No. Any editable layer can be used as an observation layer in an Excalibur project. However, using an observation layer that contains the system-managed Excalibur fields adds value to the observation collection workflow, as certain fields are automatically populated with metadata from the image that the observation is collected on.
For more information about an observation layer, see Use the Project Details page.
Excalibur projects can be shared publicly, with your organization, or with specific groups that you own or are a member of, or it can be left private when creating an Excalibur project. You can change the share setting for your Excalibur projects on the Project Details page on the About tab.
Will my custom-defined user settings still work if I access the application from a different machine?
Yes. User settings are stored and saved with your portal identity allowing you to access the ArcGIS Excalibur application on different machines in different locations while maintaining your customized experience.
Yes. ArcGIS Excalibur uses ArcGIS and its information model to consume and create content that can be applied to other ArcGIS applications. In particular, content created in an Excalibur project is written to a hosted feature service and can be used in other applications such as the web map viewer, ArcGIS AllSource, ArcGIS Pro, and web apps such as ArcGIS Dashboards and ArcGIS Insights. You can also use exported views from the canvas in ArcGIS StoryMaps templates.
Yes. You can save markup in the canvas to a project and refer to it later. To learn more about saving markup in the canvas, see Save markup to a project.
You can add or remove an existing observation layer or create an observation layer through the project details. Additionally, layers with editing enabled can be added through the Add Layer workflow in the canvas. For more information about observation layers, see Add an observation layer to the Excalibur project.
No. You can apply as many search filters as necessary when you save a query. For more information, see Search by saved search query.
Ensure that you are searching for your coordinate in your image extent. If you search for a coordinate outside your image extent, you get an error. For more information, see Capture a coordinate.
To create a GeoEnrichment definition in an Excalibur project, the following criteria must be met:
- You must be the project owner or the portal administrator.
- You must have a point and polygon feature layer in the Excalibur project, either from the web map or added as observation layers.
For more information, see Enhance an Excalibur project with GeoEnrichment definitions.
Yes, you can add any layer to an Excalibur project to use as an observation layer. You can also add system-managed fields to populate information about the image when an observation is collected. For more information, see Manage system fields and settings.
Yes. Starting at ArcGIS Excalibur 3.1, you can add an ArcGIS Knowledge graph layer to a project as an observation layer. The knowledge graph must be a point, line, or polygon spatial entity. This is only supported in ArcGIS Enterprise.
The Detect Change tool is unavailable if the web service is not an ArcGIS imagery layer that is query enabled. A minimum of two selected images are required to run the tool. For more information, see Use comparisons tools.
The Source Imagery Download option is only available if the image service has download capabilities enabled. For more information, see Use export tools.
Does my Excalibur project definition file need to be formatted in a specific way before uploading it?
Yes, the JSON file must be properly formatted to successfully create an Excalibur project. You can find the format for projects with a single focus image layer and projects with observation layers in Upload an Excalibur project definition file.
Yes. With ArcGIS Excalibur 3.0 and later, you can upload video and metadata files to create on-demand video layers. You can also configure a video layer to pull livestream data or listen for inbound livestream data.
