With highest regard for repeatable 3D positioning accuracy, Earth Intelect is now deploying its airborne LiDAR sensors to monitor landform change.
The exceptional resolution of the onboard UAV/drone sensors – LiDAR and photogrammetric – allow for digital terrain model differencing at regular monitoring intervals.
The technique has recently been deployed to a tidal drainage channel on the South coast and has successfully measured and modelled both the channel scour and accretion, and the flood defence bank slip. The top-down perspective allows for greater subject resolution and a much safer survey programme.
With ever-increasing pressure on our drainage infrastructure and flood defence networks, we believe this fast and effective monitoring technique will become mainstream.
