Beta Test / Technical

Gunther....

Is there anything we can do to also have these information shown up in OpenCPN?

Of course!

1. Produce some 26 or 28 hour days, and I'd be happy to fill them with code.
and
2. Recruit a few more c++ developers, and point them at the Flyspray Feature Request list.

As it is, hard priorities are necessary.
I'm on task, and I'm running as fast as I can.

Cheers
Dave

Thanks

Dave.........
It is a MS Word .doc file. I make a new try

I compare the same cm93 between Open CPN and another software, this show 2 shoals in one program but not in Open CPN. (Compare north and south of the light house in the attachment) This is my home water and I know where I could find them but looking in OpenCPN I only see a red cross in the chart. I have tried to alter the values of safety depth and the other values, but I can not come to the point that I can see that there is a shoal in open CPN. Is there a way that I can be sure of that I see all of them?

Checking 2.4.423 with the latest CM93 ver2 available, I find that the issue is already solved in the beta development. I suppose you used 2.3.1, as you posted in his thread?


The northern "red cross" has been replaced with "rocks awash" and the southern with rock "always submerged".

Thank you for your answer. I am on the the beta 2.4.423, XP SP3 and CM93 jan-2011

This is a mystery! No matter what I do, 2.3.1 or 2.4.423 , three different editions of CM93, no way can I get your "red crosses". I tried different vector chart settings as well.

I know this ... - it is even hard to keep step to keep the website up to date.
But I did not know that this task is already on track (even though I try to follow the project's tracker regularly).

So all is fine if it is just a matter of time ...!
In the end I still have to learn C++ to help you ... !

PS: I attached Jan's screenshots:

It could just be a stale cache thing.
Go to the ? button. At the bottom of the "About" tab note the location of your log file. Close down opencpn. Go to he directory that contains the log file.
Rename the "chartlist.dat" and the folder "CM93....". Then restart.
Any difference?

Thanks. I've seen it in the documentation and wondered what it meant.

Thomas....
I am also scratching my head
On the north red cross it say:
Feature Class: UWTROC
Position: 057 59.6977 N 011 32.1382 E
Attributes EXPSOU shoaler than range of depth of the surrounding depth
area(2)
WATLEV awash(5)

and the south red cross say:

Feature Class: UWTROC
Position: 057 59.2860 N 011 32.1050 E
Attributes WATLEV always under water/submerged(3)

When I installet a one year older CM93 set, then the red crosses was no more. So something differ in the 2 sets

The text from the one year older is
North:
Feature Class: UWTROC
Position: 057 59.6980 N 011 32.1355 E
Attributes
EXPSOU shoaler than range of depth of the surrounding depth area(2)
WATLEV awash(5)

and South:
Feature Class: UWTROC
Position: 057 59.2863 N 011 32.1022 E
Attributes WATLEV always under water/submerged(3)

Strange.....maybe you can see something?

Thomas.....
No difference
It is still strange that the set of CM93 is showing all details in MS but not in OpenCPN

You can turn red crosses on and off by changing the 'safety depth' value in Toolbox / Vector chart...
Exemple
1 - Safety depth set to 5 meter
2 - Safety depth set to 10 m

Shallow : 3 meters
Deep 10 meters

Object query
EXPSOU shoaler than range of depth of the surrounding depth area(2)
WATLEV covers and uncovers(4)

Thank you for your answer. Got your point.
But if you set your safety depth to 3 m, the you have red cross. With a higher value the red crosses go away and you can see the shoal.
My wish is to have the Safety depth on 3 m (because 3 m is a good value in the Swedish archipelago) and have no red crosses visibly. I want to see "everything"

Sorry, I'm not sure I get your point.
If you set your safety depth to 3 meters, all shoals reaching above 3 meters in deeper water will come out as red crosses, as a conspicuous warning. And you still see 'everything'.

On the pic, I've set shallow depth, safety depth and shallow depth on 3 meters. Now lighter shade means safe water, unless there is a red cross meaning a shoal less than 3 meters under the surface in that safe zone. The dark blue (between 0 and 3 meters, gray (uncharted or obstructed) or green (tidal zone) areas mean danger zone.
Note how conspicuous are the two shoals shown as red crosses in the safe zone (they would show as a the classical cross with 4 dots with other settings)

Maybe this is a question of taste.
In a paper chart you see "everything". With this setting it is no longer a shoal it is just a red cross and I have to search for information what the red cross stand for. So in my opinion it is better to show all information directly on the chart independently of the value of the Safety depth.

On electronic charts, the red cross is precisely defined as
"isolated danger or depth less than the safety contour" (see pic)
It obviously could not exist on paper charts where there is evidently no notion of 'safety contour'.

We'd better get used to it...
