Targeted High Resolution, High Accuracy Topobathymetric LiDAR

Monitoring change just below the surface with UAS topobathy LiDAR

Under the right conditions, topobathymetric LiDAR can be one of the most powerful tools for analyzing and monitoring hydrography and topographic surfaces. Innovations in unmanned aerial vehicle technology allowing for longer flight times with heavier payloads have recently opened the doors for smaller scale, targeted topobathymetric LiDAR surveys to be conducted.

Whiteout Solutions is one of the only geospatial technology companies offering UAS based topobathy LiDAR services. Our long haul UAS platform mounted with a Riegl VQ-840-GL is capable of mapping up to 15M below the water surface and 2.5x below secchi depth. With flight time up-to 40 minutes, we’re able to collect over 1,000 acres of point cloud data per day with 200 points per square meter and up to 2cm of vertical accuracy.

Here are a few ways Topobathy LiDAR could help:

  • Identify areas experiencing coastal erosion and assess the extent of the damage
  • Measure the effectiveness of sediment restoration efforts and identify areas that need
    further attention
  • Design and plan engineering projects with highly accurate data, reducing the risk of
    errors and delays
  • Monitor changes in the environment over time, allowing for proactive management of
    coastal erosion and sediment restoration efforts

Utilizing our extensive knowledge of aerial surveying, Whiteout Solutions can deliver valuable insights into both the terrestrial and aquatic environments. Whiteout Solutions has worked closely with public, non-profit and private organizations to bring complex and expansive projects to fruition, we are always a ready and willing partner.
