The ArcGIS Excalibur on ArcGIS Online Early Adopter Program gives you access to the image and video analysis application now available in Online! 

Excalibur provides you with the capabilities to perform search and discovery of imagery and video, perform analytics, and share derivatives directly within ArcGIS.  You can create markups and measurements, create feature data through the observation collection process, detect change, perform deep learning, and apply image enhancements to imagery with these built-in analysis tools. 

To participate you must:

• User Type: Creator and above
• Credits: Credit usage for imagery analysis depends on the number of pixels or features processed, which incorporates the number of bands in multiband imagery.
• Be an active participant by providing feedback, submitting bugs, suggesting new features, etc.

Check out our latest announcements and documentation to get started. Use the Forums within the Early Adopter Program to share your feedback and pose any questions you may have.
