It doesn't take that long to download all the NOAA charts on a good connection, so you might consider going to an internet cafe, or to a coffee-shop with free wifi, or visit a friend, or even ask someone to download and put on a DVD or memory stick for you.

Have you tried visiting your public library with your laptop. Most offer a free WiFi connection.

Re: OpenCPN General

I came across this on the IHO Web site. You probably already know about it, but just in case it was something new I thought I'd point it out:

News Links

ECDIS Data Presentation and Performance Check in Ships

INSTRUCTIONS and RESULTS REPORTING FORM
The IHO has produced two simple fictitious ENC datasets that are designed to alert mariners to the possibility that their ECDIS software may require upgrading. Results from the checks will enable the IHO to identify how the different brands of ECDIS display and handle chart data. This information will be used to inform the IMO, national Hydrographic Offices, ECDIS manufacturers and others, so that they can take any corrective action that may be necessary.

Re: OpenCPN General

And already results? Errors in presentation part?

( Check 4 – Detection of objects by route checking in voyage planning mode does not apply, not implemented in OpenCPN)

Re: OpenCPN General

No compliance with the latest presentation library.

First is "should be", second is "as is"

OpenSeaMap versus OpenCPN resolution

Hi,

I'm new here so forgive me if this is a dumb question or if I'm not in the right thread.

Why zooming in in OpenSeaMap gives more details than zooming in in OpenCPN with the .kap file downloaded from OSM ?
See screenshots.

Thanks in advance,
Jérôme

Re: OpenCPN General

Jerome...
Because the scale at which the KAP bitmap was generated contains less detail than the zoom level at which you are in OSM on the other screenshot.

Re: OpenCPN General

Thanks for your quick reply.

Of course the next question is why the generated/downloaded .kap contains less details.
But that's a question off topic here.
Let's go to OSM forum to figure out.

Re: OpenCPN General

Here is a interesting illustration to GPS accuracy. "Ran" is aground, and pumping oil to a Swedish Coast Guard Cutter. The trace is set to 20 minutes. I suppose that what we is the see the difference between a standard GPS and the best money can buy. Or .... is the CG running something that interferes with Ran's GPS ?

Attachment 70980

The two ships should be alongside I understand? How big is the distance in meters on the plot?
Don't think that you can "offset" a GPS reception by a certain amount. And here the offset is drifting or jumping - resulting in the track.
If you have a faulty antenna or some interference, thus a instable signal and your GPS receiver is filtering the signal with some median filter you might get even a track.

Here's the screenshot from Marinetraffic. The footprint is around +/- 15m.
Not ok, but not dramatic.

Luminance is only 230 cd/MW so this screen is not really daylight viewable. I am looking now for a touchscreen to run Nobeltec and am aiming at 750 cd/m2 or higher.

Re: OpenCPN General

Hi Dave,
An easy one.
I am using two Datalux Tracer PCs for nav computers. They have a 'one button' feature that allows you to program a keystroke sequence at the press of a button. I thought shutting down was a good idea, but Cindy recommended making it an MOB button. Of course, a great idea.
But is there a keystroke, or series of keys that would be the same as hitting the MOB icon on the screen?
Thanks,
Matt
