What is critical incident mapping data and how do they work?
Critical incident mapping data, often referred to as Collaborative Response Graphics® (CRGs), combine a gridded reference system, high-resolution imagery, floor plans that are verified by a on-site walk through, and critical features to create accurate and real-life depictions of facilities and their surroundings. The graphics can be provided in electronic or digital form to assist first responders in an emergency including, but not limited to: aerial images of schools, floor plans, including room and suite numbers, building access points, locations of hazardous materials and utility shut-offs, and any other relevant location information. By providing law enforcement and first responders with crucial information, they enhance response time and help navigate the scene efficiently.
Why is an onsite walk-through essential for critical incident mapping data?
The only way to verify accuracy of a school map is to walk-through the entire site and make changes and updates as needed. Schools change every year – structurally, in the labeling of rooms, and in the locations of critical items like AEDs and cameras. Floor plans for the building are often not kept up with these changes. First responders describe location over the radio by what they see, so maps need to match the layout and labeling of the facility. Maps also need to capture how students and staff naturally talk about locations around the building – even if it is not on a sign on the wall or labeled on blueprints – as they will use this language when describing their location under stress. All this data can be only captured during an in-person site visit.
