Built for a structure’s campus and grounds, MACRO CRG’s combine a gridded overlay with Critical Incident Mapping Data (CIMD)™ such as current overhead imagery with accurate labeling for parking areas, athletic fields, surrounding roads, and neighboring properties. First responders and building administrators use the Macro CRG to coordinate crisis response external to a structure, including inner and outer security perimeters, ambulance staging areas, command posts, reunification areas, etc. Buildings that are contiguous to each other or are in very close proximity to each other will share a “Macro”.
