I need to know how you guarantee the quality of the "charts" of OpenSeaMap.

How can we be certain that the charts are both:
- Exact with respect to the accuracy of the points
- Complete regarding all objects must be available on the electronic chart to navigate safely.

This is not an issue "in the air". I would like to update as much as possible in a tutorial on French OpenCPN. I wish to inform the French users, as well as possible. This is especially important:
- France is, to my knowledge, the only country that considers the electronic mapping can completely replace the paper mapping.
- The French legislation requires us to have on board nautical charts "up to date".

I count on you to be precise in your answer.
Thank you in advance. Best regards. Gilletarom.

Because these maps (I don't use the word "Chart") are do-it-yourself nobody can ever confirm any accuracy. Don't use them for navigation!

I have claimed the developer already. I have switched back to the old icons which are far better.

OSM (=OpenStreetMap) is do-it-yourself or crowd sourced as well. Used by a lot of serious applications.

That OpenSeaMap is not (yet?) at level with official or from-official-charts-derived material is clear.
But everybody should be free to judge if this chart material is useful for one's objectives.
Navionics and other commercial providers are offering crowd-sourced bathymetry charts. That's for me in the same line. With the difference that the latter comes in a format that nobody but systems from the same vendor can use.
That OpenSeaMap strives to make their charts accessible for a broad public by offering commonly used formats is positive for me.

Gilletarom: please correct me if I'm wrong but it seems to me that France defines "up-to-date electronic chart material" for leisure crafts as "official or derived from official charts" plus updated recently (last year?).

For the Grib, Jean Pierre has replaced all the icons with png svg icons I designed it. It should appear in the next beta or 4.2. It is much better for those of us who have a large screen and, in addition, a good definition screen.
For example, going from a 10 inch to 13 inch, the icons become a little blurry.
With a 10 inch tablet, passing 1014 x 600 to 2500? 1960 were obtained tiny icons in PNG. If we enlarged the cursor is in the "Options / User interface", they became blurred.

By replacing the PNG icons by svg icons, this has resolved the issue. In any case, the icons are clear. It's very nice.

Best regards. Gilletarom

It is also my view. but since we released these cards, much as those who propose them are clear and precise on this subject.

Hence my questions. And I hope we will have a precise answer.

The regulation has changed twice in three months in the fall of 2014. It seems that the responsibility for map editors became too heavy. None of those using raster charts of the SHOM, have the right to say that it is "exactly" the SHOM charts. Just because SHOM geotiff sells them and they turn them into kap.

That said, we are forced by French law, having navigational charts on board, up to date. Choice of: paper or electronic. French regulations said that only official charts must be used by the sailors sailing under French pavilion.

re:
I wanted to edit this connection, bypassing the box "Remove connection" to make a TCP connection, I validated. I noticed that scrolling NMEA sentences provided by the GPS has not stopped.


This won't be fixed for O4.2. It's a corner case, and the fix would introduce significant risk of regression.

In my testing, the anomaly only occurs if you change the type of an existing and enabled connection in the list. Doesn't happen if you simply enable/disable, or delete that connection. And its only a transient for this instance of O. All correct on next startup.
If you find otherwise, we'll look at it again.

Should go onto the Flyspray list, so that it won't be forgotten.


Thanks for the catch.

I agree with Dave. There are many other similar "corner" cases with NMEA data streaming into OpenCPN. OpenCPN just is not set to allow the NMEA streams to change sources on the fly. If we want to allow this it will take a lot of programming and testing to check every conceivable crazy thing someone will do in regards to NMEA source swapping around. Proabably 99.9% of cruisers never change their NMEA source streams and if they do restarting OpenCPN is not a huge burden.

[transmitterdan]

I believe this is new:

First-chance exception at 0x75B1D8A8 in opencpn.exe: Microsoft C++ exception: CacheOverflowException at memory location 0x0018CE08.

I see this in the application output when running in debug mode under MSW 10. If it happens more than a few times then I believe O just simply exists which I have seen once. I do not know if this is a real problem or not.

Cannot reproduce.
Fresh build this morning on Kubuntu 14.04. All fine for me. ???

Anyone else having trouble with alarm sounds?

You may test easily by setting an anchor watch with GPS input disabled. Alarm should sound, independent of ownship position relative to anchor watch point. Thus the anchor watch function acts as a GPS validity alarm as well.

Turn on the GPS, move the watch point close to the ship, and the alarm should stop.

Thanks

AIS and anchor alarm sounds work ok on Windows 10 as does ship's bells.
