  1. Experiences from 5 years using Bathymetric LiDAR Carl-Johan Stigermark Airborne Hydrography AB 18th of February 2010

  2. Simultaneous Survey of Land & Waterwith HawkEye II

  3. Acqusition Rate4000 soundings/second in water 64 000 soundings/second on land

  4. Sea Bed Identification By return Intensity • HawkEye sea-bed reflectance maps have been delivered to a number of commercial projects Sea-bed depth map Sea-bed reflectance map

  5. Ten cases of LiDAR Bathymetry

  6. Sea Bottom InventoryTregor, France Case One

  7. Sea Bottom InventoryTregor, France • Working in 3-Dimensions • Orthophoto • Digital Terrain Model • Digital Profile

  8. Sea Bottom InventoryTregor, France

  9. Sea Bottom InventoryTregor, France • Covering large areas in short time • Up to 30 km2/hour • Resolution 1,6 x 1,6 m in water • 0,4 x 0,4 m on land

  10. Beach Restoration PlanningGulf of Aigues-Mortes, France Case Two

  11. Beach Restoration PlanningGulf of Aigues-Mortes, France

  12. Beach Restoration PlanningGulf of Aigues-Mortes France - LiDAR technology allows to describe the topo-bathymetry of nearshore areas; - acquisition of topo-bathymetric data and orthopohotos with LiDAR technology is 30% less expensive than by traditional ways; - acquisition of a very large dataset by LiDAR technology allows to improve the quality and the precision of DTMs, DEMs and DSMs.

  35. River MorphologyGardon France Case Ten

  36. River MorphologyGardon France • Unique features of laserbathymetry is • Wide range of applications areas • Nautical charting and sea bottom morphology • Marine biological habitat protection • Environment protection programs and to oversee resources in the coastal sea • Cost efficient in comparison with other survey methods • Low mobilizations costs to remote areas • High areal coverage 50-70 km2 per survey hour • Safe in dangerous areas and tidal zones • HawkEye II brings the future closer
