To improve centralized ship routing, SeaWiFS data covering all areas where these services are provided will 
be required. Daily global data at a resolution of 4.5 km will satisfy this requirement. Data of this resolution 
will enable routing services to improve their strategic advisories to take advantage of ocean currents and 
eddies. However, vessels at sea will require higher resolution data in real time to tactically position their 
vessels to take full advantage of these currents. 
If there are two parameters in the columns, the first is for a 4200 x 4200 km coverage, and the second is for 
global coverage. 
In conjunction with other sensors.
