Background 
– We are responsible to survey and map a dynamic 
environment 
 
 
– The nautical chart is vital to world economic and 
environmental health 
 
 
– We create world-class products  
 
 
– AND… We want to improve our products

NOAA’s vision to use Satellite Derived Bathymetry 
• Reconnaissance value 
– Assess chart adequacy 
– Locate possible bathymetric discrepancies 
• Selective application to the chart 
– Interim update until traditional survey techniques can 
be deployed to systematically survey the area  
– Updates are depicted as approximate, with 
corresponding caveats and notes on the chart

Crowdsourcing Efforts 
• ActiveCaptain Navigation Hazards 
– Crowdsourced navigation hazard data 
• Crowdsourced Bathymetry (CSB) 
– IHO’s Data Centre for Digital Bathymetry 
– Software based solution concept study

Conclusions and recommended next steps: 
• This is a promising potential method to extract Crowdsourced 
Bathymetry from a typical light-commercial or high-end recreational ECS 
setup 
 
Next Steps: 
• Automate parsing of GGA and DPT strings for input into GIS 
• Evaluate solution with cursory tides and transducer offsets applied 
• Establish contact with Rose Point Developers  
• Discuss possibility to adopt direct interface with Coastal Explorer 
and Rose Point ECS software to the IHO DCDB in NCEI – Boulder 
• Use this case study to work with other chartplotter software and 
hardware developers to expand potential crowd contributors
