FM Viz4D

• Visualize data of different resolution and from different swath sensors in a single environment - various multibeam sonar file and lidar file types are supported (see our supported Data Formats).
• Direct import of ungridded data to accurately and rapidly identify artifacts and features during survey quality control.
• Direct import of gridded data formats, including the BAG/Open Navigation Surface.
• Integrate support data - drape sonar imagery, nautical charts and Google Images, or add coastline, contours, Electronic Nautical Charts and point information.

Additional Functionality Available in Other Bundles

• Area based editing and CUBE¹ processing of multibeam and lidar data (FM Hydro, FM Pro).
• Direct integration with existing systems - Optech SHOALS GCS, SAIC SABER and Tenix LADS (FM Hydro, FM Pro).
• Integration via common data formats - direct read and unload of a variety of sonar, software, and agency specific formats for processing including GSF, CARIS HIPS & SIPS HDCS, Hypack HS2, Kongsberg Neptune, ATLAS SURF, AHS HTF, FAU, NGA B93, and SMA BDI (FM Hydro, FM Pro).
• Integration to hydrographic database and charting solutions including ESRI PLTS Nautical Solution and HydroTeam (FM Hydro, FM Pro).
• Perform sounding selection for charting or shoal-biased data thinning (FM Hydro, FM Pro).
• Create Bathymetric Attributed Grids (BAG), and Sounding Density Surfaces for quality assurance (FM Hydro, FM Pro).
• Process backscatter data for the creation of mosaics or scalar surfaces² (FM Geocoder, available standalone or as part of FM Habitat, FM Pro).
• Perform remote seabed characterization using ARA , Angular Response Analysis, for seabed texture plots and chart anchorage information²(FM Geocoder, available standalone or as part of FM Habitat, FM Pro).
