CityMapper 2

The citymapper 2 is the latest Leica sensor.

It is a hybrid sensor composed of a high performance lidar and 6 large format 150Mp cameras.

This new multifunction sensor allows all types of acquisitions to be carried out simultaneously: 

  • photogrammetric quality vertical shots
  • oblique shots in 4 directions
  • high density lidar survey.

The applications are numerous:

  • urban modeling
  • electric line
  • transport infrastructure (road, railways)
  • lidar projects (forestry, archeology, DEM and high density DEM)

Lidar offers all the new advances:

  • pulse frequency up to 2MHz (2 million emissions per second)
  • great power allowing to fly up to 5000m above the ground
  • circular scan mode ideal for modeling vertical surfaces (buildings, trees, pylons, poles)
  • Full Wave Form recording mode
  • management of very rough areas (Gateless mode)
  • up to 15 echoes per emission with a minimum distance of 30cm between 2 echoes
  • a perfect distribution of points (homogeneous density in the center and on the edges of the FOV)
  • a gyrostabilized platform to correct the imperfections of the flight

cameras:

  1. high sensitivity CMOS sensor ideal for better radiometry in shaded areas or low exposure (low solar angle)
  2. calibrated camera of photogrammetric quality (geometric precision <1 pixel)
  3. mechanical image motion compensation even on obliques
  4. allows you to fly at 5cm at high altitude and at high speed (ideal for areas with heavy air traffic: Paris, Geneva ...)
  5. strong rate 6 images of 150Mp every 0.8s.
