2017-02-06 00:17:42 - Global land surface wind speed
Hi,

I´ve been trying to find a reliable source to have the wind speed and direction data over global oceans. My first objective is to load datas into Matlab using Mapping Toolbox.
Below is the format accepted to import.

(https://www.mathworks.com/help/map/file-import-and-export.html)

What kind of format is the weather updates (WX Weather) come in Sailonline.org.

Is there any kind of server (http) to conect to have the online data?

I´ve been trying to find something in "Google", but I did not find to much sources about the subject.

Below is the most acceptble information I got.

If it is possible to give me a way I will be pleasure.

Maybe openweathermap meets your needs?

What are you trying to do with the data. There are lots of options, which is the best depends on what you want to do with it.

Hi Kroppyer,

Thank you to the option you gave me.
The first objective I have is prediction route and performance routes. It´s a quite early to have any fixed idea. Second objective is take some new materials to understand better about the subject(that is how I create relation between things that I don´t know to much.... :) .)
Within this time I've been seeing tools that I was not aware of and are very close to what I was needing (I got it at SOLFans). And I could realize that one of the tools was made by you.
I tried to download but the server was down.(can you send me the link to download? )
Another point I realized is that brainaids has tools to download the grib files of the reggatas....it at first moment to me appear to cover what I was needing (but I need to check later....I´m at the moment trying to understand better the big amount of formats we can have Geodata... ). Do you know if the background image (World wide) we have at Sailonline is a raster file?......I´ve been downloading some vector files (.shp) to have a world wide picture as a background before start create the weather layers....when I load the image the resolution was so bad compared to the background image we have at Sailonline.

Thank you.

You can find my tools on http://sol.kroppyer.nl/

To find tools created by the community for sailonline, and information shared within the community, http://solfans.org/ is a good place to start, as is the "links"-page on sailonline: links

Weather and maps used by sailonline both originate at NOAA

Have a look at routers like QtVLM or BWR.

When you start creating tools yourself, let me know. I'm happy to provide you with the information you need, as long as your tool will be freely available to all of the sailonline community.

Ok. I apreciate your info.

Oh...sure.....
Thank you for offering assistance with the materials required for the tools. Anyway, I believe that it will still take some time to exist, because I need to improve on programming techniques in relation to this type of subject.
Thank you very much your help.

Current Races:

The Vineyard Race 2026


For the 16th consecutive year, our SOLers are invited to tackle this iconic 250nm overnighter. The classic route charges out through the sound, leaves Buzzards Bay Light to starboard, rounds Block Island to starboard, and heads home.

This year's weapon of choice is the Beneteau First 47.7. A proven performer since its 2012 SOL debut, this Farr-designed cruiser/racer excels at leading real and virtual handicap fleets. Success will demand sharp tactical navigation, so watch the polars closely to conquer the sound's shifting winds!

Welcome to the fourth leg of our MIG series. This time we're racing the Sooty Shearwater on their migration from the breeding grounds in South America to the northern Atlantic. This is also part of our Ocean Championship, and as such the third race of OCQ3 2026. This race will be sailed in our Gunboat 90. Race #2055

New Ice Age 2026 - Scott Base to Neumayer Station


To complete our DN circumnavigation of Antarctica and our 4-race ice-boat marathon series, we continue clockwise, now departing from Scott Base back to Neumayer Station. It’s about 3500nm back as well, which, as said if there’s wind at all, should, well-wrapped in your DN-cockpits, not take you much more than five days. And remember: charts down here are unreliable – what is land and what is ice?!

Cross the Convergence 2026 - Tenerife to Fernando de Noronha


The sixth race of our series of ocean voyages across the World’s convergence zones takes us back up the Atlantic to Tenerife, from whence we will depart on a classic transatlantic passage to Brazil’s Fernando de Noronha. It’s 2150nm as the albatross flies, but you will undoubtedly have to take some and sometimes sudden detours to get your Volvo 70v4 through the doldrums stretching across your path from the Amazon to the Niger.
