Urban Search and Rescue (US&R) is an inherently spatial problem – whether it is a single building collapse or a wide area search. In 2021, the NSARGC Group established the SAR Common Operating Platform (SARCOP) using ArcGIS Online. The SARCOP has been successfully deployed in 11 major incidents, including the Champlain Tower Collapse in Surfside, FL. This session will discuss the people, processes, and technology that were utilized to implement the SARCOP and lessons learned along the way.
