Harvey-Lynch, Inc. - Turnkey Solutions - Integrated Multibeam & Mobile LiDAR Solutions

Multibeam & Mobile LiDAR Solutions...

This turnkey solution was designed to combine the capabilities of Multibeam Echo Sounders (MBES) Sonars and Mobile LiDAR (Light Detection And Ranging) laser scanning systems namely our line of Reson multibeam systems and the MDL Dynascan system.

This sensor integration acquires hi-volume data in shorter periods, safer, and with less manpower making the project cost effective to levels never heard of before.

The integrated solution can be msot efficient and effective when performing surveys in Land & Marine commercial sectors such as:

Land	Marine
Prelim Surveys As Built Surveys Urban Planning Flood Plain / Drainage Surveys GIS / Asset Inventory Corridor Mapping Stockpile Surveys Rock Cuts and Fills Bridge/hydro line Clearances	Scouring Surveys Dams Rivers and Shoreline Surveys Waterways & (Ferry Crossings) Ports and Harbours Surveys Environmental Monitoring Flood Plain Mapping

Solutions & Capabilities...

The intended outcome of performing accurate surveys combining MBES-LiDAR (Reson-Dynascan) subsea and surface acquisition systems 'simultaneously', is to produce a geo-referenced data set of what is below AND above the waterline... "all at the same time".

Reduced survey durations via high-resolution seafloor mapping and small subsea object/debris detection surveys are now possible.

In combination with the super high MBES/LiDAR transmit/receive rates can produce dense point cloud datasets in a very short time.

From a single geo-referenced dynamic platform such as a small boat, ATV, truck etc. high accuracy survey data sets can now be be acquired in a safer, more practical, and accurate way resulting in far more economic operations than ever before.

With this solution we offer the following capabilities:

Customized in-depth operation support
Complete solution from acquisition to reporting
Formally trained acquisition and processing team
Tailor-made data management solution
Multiple "industry standard" data exchange format
Safest and most efficient way to collect land & marine survey data simultaneously
Ability to combine multiple system & sensor Input
Real Time 3D swath visualization and Quality Control.

When the point-clouds of the data from each of these systems are merged, a complete and single respresentation emerges. This data is especially useful for environmental assessments, engineering models, and subsea-asset integrity management & planning purposes.

How does it work?...

High resolution seafloor mapping and small subsea object/debris detection in combination with high MBES/LiDAR ping rates can produce dense point cloud datasets in a very short time and from a single geo-referenced dynamic platform such as a small boat, ATV, truck etc.

The combined MBES/LiDAR (Reson/Dynascan) systems permit the rapid production of detailed subsea bathymetry & imagery while simultaneously gathering above-water surface terrain and structure models. We intergate our Reson MBES systems with the Dynascan Mobile LiDAR instrument which has a rotational speed of 10 Hz, an angular resolution of 0.01 degrees and a range of 150 meters (systems available that scan out to 500m).

The QINSy integrated navigation and data processing software suite by QPS in The Netherlands integrates to both devices simltaneously and orchestrates the data capture in an accurate, simple and practical way. The QINSy package also provides capabilities to generate point clouds for both sensor types in realtime and into one seamless 3d terrain model.

Kalman filtering positioning techniques built in to the QINSy software allow for integration of GPS with an INS (Inertial Navigation System) enabling surveys to continue for short periods even when the navigation is being masked or obstructed which can be typical when surveying around bridges & spans, buildings, cranes, and other similar blocking structures.
