This release of ArcGIS Excalibur 2.4 has various bug fixes and improvements. ArcGIS Excalibur will now support Tile Layers, Tile Image Layers, and Map Image Layers in addition to the Imagery Layers, WMS, and WMTS layers it had previously supported. The new Count Tool allows analysts to count objects on images to quickly calculate a total. The new Bookmark Tool will allow you to save shortcuts to specific locations within a project and quickly navigate to them throughout their analysis. The new Screenshot Tool will allow users to view or save a defined area on their images as an image file. We have also streamlined the observation tools to make collecting and editing observations more intuitive.
