If you grew up with this ...
... then this is a great technology
...and if you grew up this...
... then this really hot (NOW)
Change Comes Fast

What is Crowdsourcing
• Sourcing tasks traditionally performed by specific individuals to a group of people or community (crowd) producing solutions from amateurs or volunteers working in their spare time, or from experts or small businesses which were unknown to the initiating organization.

Crowd Sourcing Oceano and Bathy Data• Coastal waters are
inadequately surveyed the amount of coastal waters that are adequately surveyed is below 50%.
– The high cost of ship surveying - about $30,000 per square mile
• Recreational Mariners
• logging depth,
• position,
• SST,
• dissolved O2,
• acidification,

Why Crowd Sourced Bathymetry
• U.S. coastal waters have never been completely surveyed, and for the areas that have been surveyed, approximately 50% of the
sounding data is pre-1940,
• It is expected to take NOAA 166 years to survey the 500,000 square nautical miles (SNM) of navigationally significant waters (taken from NOAA HSRP Report 2007).
Obvious need for supplemental chartingusing a cost-effective approach

The New World OrderTimeliness: not weeks or days - but within seconds
Connectedness: always connected,
Content: if it isn't online it doesn't exist
Choice: multiple ways to get what you want
Depth: links to ever increasing detail
Knowledge: everybody shares
Innovative: a connected search for better ways
Unlimited Workforce: anyone can add
Wikis: wiki-based information from fellow travelers
Trust: technology works, large institutions don't
Free: as in virtually costless

Current official charts have soundings from all these sources

Its OK to Challenge the Current Charts and Products

Crowd Source BathymetryDelaware River 2004
265,000 gallons of oil into the Delaware River
115 miles of shoreline affected
The Athos I collided with three uncharted and undetected submerged obstructions in the channel and anchorage.
The Athos I incident alone has cost the ship owner and his insurer over $165 million.
The true value of wildlife lost and port commerce delayed or deferred cannot be calculated.

Crowd Sourced Bathymetry
How many vessels passed over these
before the Athos I did?
What one vessel passes over, without knowing, or caring for that matter, will potentially be of significance to any vessel with a deeper draft.

• Weather Data– True and apparent wind speed and
direction – Barometric pressure – Relative humidity– Air and wind chill temperatures
• Water Quality– Water temperature– pH– Conductivity– Dissolved oxygen– Other possible metrics include:
turbidity, oxidation-reduction potential (ORP)
• Pollution/oil spill applications

Representative Tide Data• Over 50% of soundings are from stationary vessels
• “Float” data not only provides depth measurements, but also contributes to tide corrections
• Float data snippets range from minutes to consecutive days, weeks
Potential to extend and enhance NOAA’s current fixed-tide-station network

Hi-Res Storm Surge Datafor Modeling & Visualization
• Application: Obtain highly localized (space, time), very-fine-scale storm surge and met data – before, during, and after tropical storms
• Utility: Selectable-location data for cell-by-cell NOAA model validation

Yes We All CanPressure for change
Use Social Networking technology
Support technologies that give tools to the crowd
Encourage standards to keep specific layers open for direct user input
Free up as much supporting data as possible
Fast lane new information directly to mariners tagged with quality level ratings
Incorporate photo realism and 3D models
Encourage and respond to user ratings
Begin to employ crowdsourcing, initially on non- regulated publications
