OpenCPN Version 2.2 Beta Test

[sinbad7]

Ref message # 178
I have reverted back to the previous OpenCPN ver. until Dave manages to correct the anomaly of foreign characters used in .BSB/.KAP filenames, (æøå) and others.

Example: ÖGÖT_3.KAP - VÄN_4.KAP - Östra Hjälmaren (1986).kap

(OpenCPN freezes up when it encounters a BSB/KAP filename using foreign characters.)

Tore...

Which version, please, has the Swedish .KAP file problem?
Which version did you revert to?

Thanks
Dave

Dave..

I am referring to the latest ver. beta 2.2 1007.
When rebuilding the chart database,OpenCPN freezes up when it reaches my Swedish .KAP/.BSB directory. After removing the directory,all is back to normal.
It is not a faulty individual file,but all containing characters shown i my report.

While I remember, is there any way you could restrict the display in the AIS Target list to contain only targets contained in the display window? This would result in a much quicker display,especially within areas with heavy traffic. It would also extend the usability of OpenCPN to us who have now become 'armchair sailors'.

Have a look at the Siitech prog. with some 12.000 targets..

Thank for a truly great program.

Dave..

Here a sample .kap file from Sweden.

Dave..

Another strange thing happened with ver. 1007.
One of my converted .kap maps did not retain the AIS targets properly when panned. Instead the targets were displaced a few millimetres E-W and N-S
depending upon where the map was panned. In other words the targets did not lock on to the map.

Having reverted back to an older version of OpenCPN,all was normal again with this particular map. All my Swedish maps also loaded normally with this version.

Dave..

I have reverted back to Version 2.1.0 Build RC615a which is working fine until
the bugs of 2.2 1007 has been fixed.

Where? I didn't see it. What type of chart? Does it show up on all charts of that type? Does it show up on other types of chart? Can you perform an object query on it? What are the results? More details would help.

Hello Fabbian, thanks for your quick response. I am talking about the yellow AIS target at the centre of the screen - it has some blue bit attached to it. I see the same on the ferries that pass by my marina here.

This blue bit is the European "Blue Paddle" signal, commonly seen on inland waters to indicate that the vessel requests a "stbd-stbd" passage or crossing.

Mostly used by heavy ships proceeding down-current requiring to be on outer, deeper part of river bends. Bit is set by captain by a switch on AIS transponder. Save VHF radio bandwidth, since no passing arrangements call need be made.

Should be deactivated when at sea, I believe.

Not seen in US at all.

Anyone else have amplifying info?

Thanks for the quick response Dave, opencpn development seems to be going on at such a pace now i hadnt heard of the implementation of this feature? The target in question is the oostende - ramsgate ferry in the north sea, I believe it doesnt travel in inland waters at all; it does, however, navigate some famously narrow channels in the shallows off dunkirk.. so it would make sense.

The indicator might be more intuitively accessible if it was spelled out in the ais target query window (although that is getting a bit packed by now). I guess "RTFM" might be helped

Hugely enjoying the rate of turn indicators by the way!

In Europe it is called the "Blue sign". It is not only used downstream but also to make profit (downstream) or to avoid strong currents (upstream) in the river e.g. in curves.
It is incorporated in the so-called Inland AIS standard and forms two (spare) bits in Message 1. The Inland AIS standard is almost equal to the Class A standard but some inland specific changes are included. Therefore you will see inland ships as Class A AIS stations on your display in Open CPN. Other changes are: no IMO number but a European Vessel ID number which is transmitted in an Application Specific Message 8 which contains a number of specific data fields. This is not decoded in Open CPN.

The Blue sign can be set by hand or automatically when the Blue sign has a switch connected to the Inland AIS box.

Inland AIS as described in the Inland AIS standard is typical for European waterways only (till now) e.g. river Rhine, Danube, etc. and is mandatory in some European countries. Some other European countries are introducing Inland AIS on a large scale now and on voluntary basis at this moment. In the US, inland ships are using 'standard' Class A stations.

I hope this helps you.

Ami,

please go to Vector Chart Display | Official OpenCPN Homepage and read especially the first sentence ... .

Gunther

PS:
@Dave - maybe this should be enabled by default ...

Hello,

I'd like to give the latest build a try, however the exe-file is a 1007 build where the Ubuntu build is 1024. Could someone pls be so kind to update the exe-file (I don't have the tools installed to compile or so....)

Thnks in advance!

[nohal]

George,
be a bit more patient. The current code is not considered stable enough to make a beta release. If you really really want to have the latest (but not always greatest) build, you will have to follow Compiling the Source in Windows | Official OpenCPN Homepage and build it yourself.
