ArcGIS Excalibur<\/a> is a web-based image analysis app that allows users to access, analyze and share imagery for informed decision-making. Excalibur streamlines visual analysis through comparison tools that make it easy to find differences in imagery that can match up to activity change in an area of interest such as missing or moved objects at an airfield or port. \u00a0<\/span>\u00a0<\/span><\/p>\n

The Detect Change tool<\/strong> in ArcGIS Excalibur helps automate identifying change occurring between two images. \u00a0Instead of manually comparing two images over the same location taken at different times, analysts can use the Detect Change tool to conduct automated pixel-based comparisons where only those pixels that are different between the two images will be highlighted to easily identify change.<\/span>\u00a0<\/span><\/p>\n

This can help with anything from loss prevention to inventory tracking by making it easier to identify if objects were moved, missing, or simply require attention. For example, as an analyst tasked with identifying any change in aircraft activity over different dates or times, you can use the Detect Change tool along with other comparison tools in ArcGIS Excalibur to discover this type of insight. Below details the steps to begin using the Detect Change tool today in your workflows.<\/span>\u00a0<\/span><\/p>\n
