Partly thanks to Paul Higgins (Sample
), my problem, which is to display SST data as a map/chart you can navigate on with e.g., OpenCPN, so as to take advantage of surface currents, or to find a promising fishing
spot, or just to better feel the movements of the sea and to entertain a crew during a bay or an ocean crossing
, is now solved
Such data are available for free via numerous websites, e.g., Ocean monitoring and forecasting - MyOcean
(please, post here web sites addresses that could be more convenient for other specific areas). When you access the catalogue, choose an area, a parameter (temperature) and observations (as the product type). At best, SST data are proposed with a 1-km pixel on a daily basis, but you can also get temporal and/or spatial composites (to manage with a too large cloud cover). For the Mediterranean
Sea in particular, five products are offerred among which the fifth one (1-km, daily) provides the most interesting data via «*info*». Then, after having selected your date and sub-area, adjust the colour scale to have it covering the SST range of your sub-area (the round button), and open it in Google Earth
that you let open.
You then follow the classical procedure to display Google Earth
data as more or less transparents maps inOpenCPN, using the Paul's GE2KAP software
(Paul recomends dowloading the latest -at least V 9.4.35- version), the use of which is widely described online.
In case of any comment or any need of help, please, send me an e-mail.
Enjoy navigating with an info about the SST …
