Enabling transformation of the public safety sector

Above and below ground 3D data modelling and analysis

PROJECT: Evacuation route planning in Berlin’s underground U-Bahn and adjacent city streets
CUSTOMER: Safety and security demo project
SOLUTION: Leica Pegasus:Backpack
OBJECTIVE: Map above and below ground infrastructure to build an accurate 3D map of one of Berlin‘s metro station for scenario modelling, viewshed analysis and evacuation route planning.

The Stadtmitte U-Bahn station in Berlin’s centre is one of 173 underground metro stations in the city. This is the access station to Gendarmenmarkt, Berlin’s most famous square. Adjacent to the square, upscale shops, restaurants and hotels attract thousands of people every day, making risk management and evacuation planning imperative to visitors’ safety.

Until recently, documenting underground metro stations, city streets, or other infrastructures was a time consuming and complicated process. This is why particularly in crowded cities solutions, such as the Pegasus:Backpack wearable scanning technology, facilitate the process and make 3D mobile mapping a cost-effective and efficient technology to collect and evaluate data. Point clouds and imagery are used to produce 3D city maps and models with a high level of detail and accuracy.

Review, plan and create models for:


  • Analysis of existing above and underground emergency evacuation procedures and scenarios
  • Planning of new evacuation routes with best and worst-case conditions
  • Unlimited kettling for maximum crowd control and minimum riot damage
  • Unlimited view shed analysis for optimal surveillance and support team placement

Capture critical 2D and 3D data of


  • Existing evacuation/egress routes for analysis and review of obstructions
  • Existing access/ingress routes for analysis and review of obstructions
  • Up-to-date floor plans and elevation models with centimetre accuracy
  • Signage including fire hazards, extinguishers and exits
  • Wheelchair ramps, elevators and stairs, interior doors, windows, and building exits
