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.

Cross the Convergence 2026 - Sao Tomé to Tristan

The fifth race of our series of ocean voyages across the World’s convergence zones takes us back south down the Atlantic from Sao Tomé on the Equator to Tristan da Cunha on the edge of the Roaring Forties. It’s 2500nm; in your path the Benguela winds and current along the south west African coast, and behind that the St Helena High stretching halfway to South America. So, mind where you go in your Volvo OD65 version 3 (based on sampled real-life race data by kroppyer)!

New Ice Age 2026 - Neumayer Station to Scott Base


For a second-half of long-distance ice-boating, we take our DNs to Antarctica for a circumnavigation of that continent in two legs clockwise, in harmony with the prevailing winds (such as there are), beginning with a race from Germany’s Neumayer Station to New Zealand’s Scott Base. It’s about 3500nm, which, 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?!
