Data Import

• Import multi beam echo sounder data (MBES) from survey datagrams – Formats: Kongsberg Maritime (Simrad), Reson, Eiva, GSF, Atlas, Elak, MB System etc.

– Toolbox for correcting for calibration errors

– Correct for tide

– Replace or edit navigation, gyro, heaver, roll, pitch, sound velocity

– Convert to XYZ

• Import XYZ data – Kongsberg Maritime, Eiva, Ascii column, Shape, Dxf, GSF points etc

– Eiva NaviModel db + binary NED

Data editing and filtering

• Edit MBES and XYZ data – Flagging without removing

– Can revert deletion of points

– Automatic filtering • Surface filters

• Threshold filters

• Polygon filter

– Point Cloud Editor • Manual selection

• Remove or extract

• User flags and deletion flags

Products

• Create surfaces (digital terrain models) – A choice of algorithms (for different types of data)

– All algorithms can be limited to be within a defined polygon only

• Create BAG (Bathymetric Attributed Grid) and GeoTiff – Compatible with the ArcGIS for Maritime: Bathymetry extension

• Create contours, profiles, points

• Visualization in 2D/3D – ArcGIS (ArcMap, ArcScene)

– Geocap Seafloor

• Optional: Geocap Datalink for ArcGIS

for ArcGIS

• Data showing features between the multibeam echo sounder and the seabed

• Showing details which have to weak signals for the depth detection

• Typical use; Locate seabed leakages, e.g. gas seeps and fresh water seeps

• Locate biomass like fish schools

• Wreck surveys, find details not visible on multibeam data (e.g. masts, anchor chains …)

What is Water Column Data?

Why analyze Water Column data?

Presentation by Terje Thorsnes, NGU,

Challenge with Water Column data

• Many survey lines

• Large areas

• Huge amount of data – Size of depth value file (*.all) : 245 Mb

– Water column file (*.wcd): 1 642 Mb

– ~ 12 Gb/hour

• Time consuming to manually check all lines

• Brick technology can automate analysis

Geocap Water Column Explorer for ArcGIS

• Import MBES Water Column data – Currently Kongsberg Maritime datagrams (*.all, *.wcd)

• Build Brick cube

• Automatic conversion to depth

• Automatic conversion to world coordinates

• 3D visualization – Together with bathymetry

– Together with seismics

• Use ArcGIS (ArcScene) to visualize “bricked” water column wedges.

• Also available as module in Geocap Seafloor

Geocap Water Column Interpreter for ArcGIS

• Geocap Interpreter Machine for water column data – Automatically filter away “nothing”

– Use seismic interpreter techniques to automatically find features in the water column

• Locate seabed leakages, e.g. gas seeps, fresh water seeps

• Wreck surveys, find details not visible on multibeam data

• Locate anchor chains

Expression from seismics 3D body generation: «Put Fire to the Fish» (or gas, freshwater etc)
