- Volumetric calculations for landfill and dredging applications
Suggested Scanners
The Riegl LMS-Z420iand Z390 are typically used for coastal survey work.
Typical Projects
3D Laser Mapping have undertaken a number of surveys for the British Geological Survey where we have visited specific locations of coastal erosion every six months. These locations are typically very isolated and are up to 2km from the nearest road. However, due to the flexibility and portability of the Riegl laser scanners, the scanners were either mounted on a quad bike or in a backpack. Control of laser scan data was made with GPS. Scanners have also been used in the mapping of extensive areas of beach and intertidal zone, many kilometres in length, to provide accurate and detailed baseline information for subsequent coastal monitoring projects or as part of Shoreline Management Plans.

ATM3D, a 3D laser scanning company based in France, undertook a coastal study of the large Northern Dam of the Port of Bayonne using a Riegl LMS-Z420i. A pdf of this study can be found here.
