Geospatial Multibeam Point CLoud Mapper

Baywei M1

With integrated INS and SV calculation


Revolutionary!

Extremely portable Multibeam Point cloud mapper that generates, and outputs geo-referenced XYZ .  

No Topside.  No SV Sensor.  No SV Profiler.  Proprietary groundbreaking methodology that utilizes the sonar signal itself to extract speed of sound information.  No Hydrographic Software needed for collection or processing.  Integrated Trimble Applanix in the sonar head. 


Outputs XYZ --> Simply bring into CAD, or point cloud viewer, or HYSWEEP or similar


Designed for the Geospatial user who needs rapid assessment of underwater terrain, scour, infrastructure, or general mapping of lakes and riverbeds. 


It truly is a first of its kind!  An all-inclusive auto-pointcloud mapper controlled and monitored via a simple web based app.  

  Who would have thought it could be this simple?
