      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

Not sure I follow. If I have a grib files from NOAA/etc., how do I view in google earth? Cool stuff if it works, Google Earth rocks.

Download the file under the link, change teh extension to "kml" and double click. Very cool.

As of late I have been working with Google Earth and overlaying data on the maps. For example waypoints, routes and tracks. Easy enough. Now I have GRIB Weather files working.

 

right click on and save a Sample KML that can be opened in Google Earth

 

For those who do not have Google Earth here is a Screen Shot

 

Hey, sportboat! Nice layup. Well done sir.

??

 

the html code from the link? or after you have downloaded the file?

 

make sure you are actually changing the .xml file to a .kml file (ie, you aren't just ending up with a file named 'grib.kml.xml'....

 

 

where is the best place to get the damn small gribs? i can't seem to sift through the NOAA site enough to find where to download them??

 

very, very cool....

How can you import grib info to overlay other locations?

This will be a new feature in our next version of our Mac nav software. That is you can load a GRIB file (.grb) and then "Export To Google Earth". That produces a KML file that Google Earth can open. XML format files for transfering nav data have become much more comming (i.e. GPX for waypoints, routes and tracks). Hopefully the Windows nav software will follow suite and support Google Earth.

Correct me if I'm wrong, but this doesn't sound like a very useful feature for actual navigation - don't you need an active high-bandwidth internet connection to use Google Earth?

 

In any case, there are several good GRIB viewers out there. I use GRIB Explorer from OCENS (~$100 I think), and there are several free ones. Not sure about any free GRIB viewers for Mac though.

 

My favorite free GRIB viewer for windows is the demo version of Expedition, with the free C-Map charts as a background.

 

Given the spacing between grid points on even the COAMPS GRIB's, there isn't really any reason to have a very detailed background map.

Yes you need some software (ours) to convert grib file (.grb) to Google Earth KML (.kml). Once converted they can be viewed by anyone with Google Earth. My hope is someone will create a Windows tool that does the same. Our software is OS X only.

 

It is true you need a wifi connection for Google Earth, but that is becoming more common in marinas and also on cell phones such as Verizon. Eventually it will be world wide with Sat. Also storage prices are coming down all the time so I can imagine holding all of Google Earth on a local hard drive.

Nice work! The message here is ; do not try to deliver from Flattery to SF at this time of year.

 

Not true...you just need to pick the right window, which is slowly closing but not shut completely, yet.

Sportboat, never looked at GRIB, what's the format like? Straight forward or tricky? Got a spec for it? Should be able to bash a GRIB -> KML web page up fairly easily.

 

Rgds,

I've seen estimates of the Google Earth database being a few 100 to maybe 1000 terrabytes, and growing rapidly as they add high res images for more and more of the globe. one terrabyte = 1024 gigabytes. Supposedly, that doesn't count mirroring. It'll be a while before we're carrying that kind of storage around on sailboats. I guess you could just store areas of interest.

 

Still, google earth could make a nice GRIB viewer for use at home, or wherever there is high speed access.

Don't know the particulars, but at work the boys "cache" an area of interest in Google Earth, then disconnect, go out into the field and run Google Earth with no internet connection.

I wish I was more literate in this stuff. I just listened to a radio interview with the guys making a globe that glows different colors depending on how a stock is doing. They also had some weather products. The thing interesting I got out of the program was the so called 3rd wave of internet technology, smart devices that are tuned to internet datacasts and behave accordingly. Like an umbrella that glows when it is going to rain or they have a Stockorb that tracks the market. Several companies already using it in production and project management. One of the big points was that people can gather data when it is conveyed as a color in a much more intrinsict and instinctual way that numbers or even icons like arrows. It easier and quicker to absorb into our brain. This made sense to me. You learn colors before just about anything else. I think the company was called Ambient.

 

Now, this does not seem so hard to configure to sail electronics. So imagine a programable color plate on your mast that glowed through a spectrum of colors as you approached optimum VMG, lifts and headers, whatever. You program it as you choose. No need to focus on doing math in your head and remembering numbers just catch the colors out of the corner of your eye while focusing most of the attention on the environmental data. I am hoping for a discount if this helps someone here develop a product.
