NEW PATHS. NEW APPROACHES
• Another tool to the
hydrographer
• High value for: Planning
Chart QC
Added chart contents:• Remote shallow areas
• No other recent source data

NEW PATHS. NEW APPROACHES
• You can do it (GEBCO Cook book)
6 simple steps
Standard GIS tools
Publicly - available satellite imagery
(multispectral)
Easy steps for a trained
hydrographer
• Professional Services
Large volume processing faster
Augmented skill resources
Expertise support
Consulting

Who can do it ?
NEW PATHS. NEW APPROACHES
SDB Policies
• NOAA implementation Policies – NOAA
Nautical Chart Manual
Procedures in place
Support IHO for
developing nations
activities
Coastal Area
Misleading chart data or
dynamic seabed
No critical under-keel clearance
requirement
No recent survey
(acoustic or ALB)

NEW PATHS. NEW APPROACHES
SDB Products
• Cartographic
Representation Approximate depth curves
CATZOC “C”• Full area search not
achieved, depth anomalies
may be expected
• Low accuracy survey
• Uncertainties (Coming
Soon)
