2D and 3D maps of building floorplans can improve response time of public safety personnel who are responding to active shooting incidents.

Entropy Group LLC, a security technology firm, reduced the time needed for public safety personnel to engage a simulated active shooter by providing the team with site floorplans created from 3D laser scan data.  Prior to the exercise, the firm scanned the entire 112,000-square-foot building interior in just 2.5 hours with the GeoSLAM ZEB-HORIZON 3D mobile scanner.

“In the role-playing scenario staged at a mega-church, the off-duty police officers reached the shooter in up to 21 percent less time using a 2D floorplan generated from the laser scans,” said Robert W. Myers, CEO of Entropy Group LLC.  “However, we expect engagement times to drop considerably by leveraging the 3D scan data to create virtual reality training simulations.”

Based in San Ramon, Calif., Entropy Group was established to save lives during active shooting incidents at schools and churches by providing law enforcement with the situational awareness information they need to reach perpetrators more quickly inside complex building spaces.

The firm uses the GeoSLAM ZEB-HORIZON handheld mapping device to capture 3D scans of school and church interiors, including small offices, classrooms and closets.  The GeoSLAM software generates accurate 2D floorplans for use by responders, either hardcopy or digital, to navigate the interior of the building.  The same data set can also be used to create virtual environments where multiple officers train on computers to respond to attack scenarios in realistic, immersive 3D simulations of actual schools and churches in their jurisdictions.

The handheld ZEB-HORIZON laser scanner allows users to map interior and exterior spaces in 3D at walking speed.  The device captures up to 300,000 points per second with an accuracy of 1-3 centimeters up to 100 meters from the user.  SLAM technology ensures points are tied to local coordinate systems even in interior spaces where GPS/GNSS coverage is poor.
