Do we need/want an AIS filter?

I can agree but something is strange with the present code in Dirks GitHUb. OCPN won't close down completely but is still in background. I suspect that the temporary slider box is not properly killed, but that's not verified.

Yes Dirk says sliders are temporary to get the right adjustments for
SOG, CPA, TCPA, Range & Size. Currently CPA & TCPA don't seem to be working based on setting those sliders at 100 (maximum effect) and the sliders for the others at 0.

Håkan points out that there is a problem in the main repos OpenCPN where CPA is calculated at 800 nm, which is out of range of the setting, so that might be affecting the RooieDirk TargetScale version too, making CPA TargetScaling not work.

BCN what is ext Beta? The next beta? I suppose wrapping his Targetscale into the next beta would be a good conservative approach, allowing others to test it more widely. Maybe we wait today and see if Dirk is back and responds. He's been working hard on this and there's somet with AIS in the main OpenCPN too.

Quite frankly, this addresses one Display problem many others have commented on, with various alternative solutions, and this solution does not remove any data from display, just resizes based upon importance. I am not sure it will slow things up that much either.

@all
Been underway the last 3 day from first, till last day light. Tomorrow one more lock
I found the problem with the CPA and TCPA settings. Weight was linear with value. Made it reverse with value now.
After some trying I'm not confinced that the TCPA value is any good for determining if a target is important or not. A vessel passing on 10NM distance with a TCPA of 1 minute is not important at all. Maybe combine it with CPA, if vessel is still approaching more weight then when vessel has passed already.
I will have a look at it tomorrow.

Dirk..
By more or less a mistake I posted on another thread about this plugin. If you want, follow this http://www.cruisersforum.com/forums/...ml#post1988937

Dirk,
I will try to find opencpn.ico and put it in there, but something is missing.
Thanks.

PS --didn''t find a solution.

Rick...

I am working on the missing files now. I will have a fix shortly.

Thanks
Dave

Dirk...

Minor fixups on the Pull, merged into master. Looks good so far.

So, can you give us a tutorial on the functions and behaviour of this Feature? Especially, tell us about the filtering/sizing logic, and the tool icon cycling, so that we may update the docs.

Thanks
Dave

[Hakan]

Scaled AIS in core code builds fine with VS2013.

The new scaling logic is much better. Not less with the new default values. So - a tip for those having used the function before: Delete all five "AISScaledNumber........." in the config file to write them to default on next start.

Would it be possible to remember the last scaling mode to next OCPN start, as erlier discussed? It may be prepared with the "AISShowScaled=1" in config but is not yet used I think?

Very nice Dirk!

Thanks
Håkan

[Hakan]

When I changed to Traditional tools style I saw the new icons for the AIS function. Normally I'm using the Journeyman style and there the icons are as before?
Would it be possible you make icons for the scaling feature also for Journeyman?

Thankyou Dave, Dirk and Håkan,

1. Compiled main Opencpn, opencpn_4.1.1108_GIT7-32ee195AddMissingImagefiles
2. Deleted the AIS scale settings from previous use.

I really like the Toolbar Icon AIS messages
"Show All AIS Targets." click
"HideAIS Targets" click
"Scale Less important AIS Targets". click


I also like the Menubar AIS dropdown selections (see image below)
"Scale Less important AIS Targets". click
"Show All AIS Targets." click

This all seems to work very nicely.
I am having some trouble getting the underlying checkmark for
"Scale Targets when greater than > 10 boats"
to respond however. I don't know if I have unrealistic expectations.
I think this gets checked on and off by the controls above as well, but It does
not seem to do anything from
Options > Ships > Ais Targets > checkox for Scale Targets....

Great Improvement! Thankyou all.

[did-g]

Nice work but two small things

- lost scaled down targets, black bars don't seem to be scaled.
- label text:
allow scaling down targets if more then ... targets.

[rgleason]

did-g
"allow scaling down targets if more thAn ... targets."
Under Windows this is Under Options > Ships > AIS only I am not sure if it works from that window/menu. I put a check or take it off and close and there does not seem to be a change. However it works in the other places.

How about you? Is it Linux?

Dave, Dirk & Hakan,

New compile of Opencpn today. After working with fresh compile of ocpn_draw and watchdog awhile, I tried the new AIS features in their final configuration.

1. Menubar > AIS clickable access to turn on and off AIS features quickly.
2. Toolbar clickable rolling AIS Icon to control the state of AIS, very nice.
3. Attenuate less critical AIS targets, works very nicely.

Thank you.

Through the Menubar > AIS drop down we can now quickly turn on and off "Show CPA Alert Dialogs" and "Sound CPA Alarms". We are also able to turn on and off "Attenuate less critical AIS Targets" and "Hide moored AIS Targets".

I believe these are the main controls needed when transitioning from Ocean to Coastal to Harbor conditions, so hopefully there will address most people's concerns.

Bdcat, we have your operational description of the controls for updating the manual, thank you.

Dirk, for update to the Opencpn Manual, regarding Scaled Targets, you gave a great description earlier but that has been updated by some adjustments to the parameters. Do we want to have some description of the way the algorithm works in the manual?

Dirk & Bdcat. Thank you. Have a great Xmas...
