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

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.

That's kick ass, top work. I should finish my KML course mapper.

??

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.

Very nice, SB. Any chance of a howto so that we can produce our own, or is this strictly for your software?

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.

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.

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.

Google Maps now supports KML overlays. What this means you can paste in a URL to a Google KML file. For example paste this URL into the "Search the Map field"..

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.
