ArcGIS Excalibur 3.1 is now live and it furthered an already strong functional foundation for working with Imagery and Video. There is an enhanced collaboration experience focused around projects allowing for the inclusion of supporting materials and related information. Publishing continues to increase in requested functionality to support livestream video. This extends the supported video data types through ArcGIS Video Server that can be published into the ArcGIS System of record to be utilized in downstream analysis.
This release added support for a datatype integration with ArcGIS Knowledge. This expands on the already rich ecosystem of supported layer types within the application. You can find all the details for the release in this blog which outlines new features for 3.1.
