Rapid Mapping

Rapid mobilisation and non-invasive monitoring of unstable areas

We are experts in rapid mapping and respond rapidly to disasters and hazards (landslides, floods, avalanches, etc.). We provide mapping surveys and services immediately after the event or help monitor potential disasters to minimize their impact.

Our solutions

Emergency mobilization

The increasing frequency of extreme weather events requires effective methods for documenting and managing such disasters:

  • Ultra-fast mobilization capacity
  • Operational in just a few hours in Switzerland and abroad

Very high-resolution airborne surveys

  • Safe, non-invasive surveying in complex environments and inaccessible areas
  • Simultaneous acquisition of LiDAR and photo data with high-precision geo-referencing

Our modular acquisition system enables us to carry out vertical or oblique surveys, with flexible installation on various aerial and ground platforms.

Modelling

Creation of digital twins and customized deliverables according to project requirements

  • Very high density point clouds
  • Very high resolution orthophotos
  • Digital terrain, surface or canopy models before and after the for analyzing evolution and damage
  • Photorealistic 3D meshing

Risk mapping for affected areas

Support for reports and detailed analyses, produced in collaboration with the relevant departments

  • Merging point clouds before and after the disaster
  • 3D understanding of the event and assessment of its impact
  • Drawing up and updating detailed plans of affected areas
  • Rapid identification of residual risks thanks to artificial intelligence

Our advantages

  • The use of a helicopter for a non-invasive approach, enabling rapid intervention in complete safety, even when the terrain is unstable, steep or difficult to access.
  • The efficiency of our helicopter-borne sensors enables us to survey large areas in a very short space of time.
  • Our experience and data can help you to understand, prevent and manage risks and disasters.
