My BSB charts are indicated as borders but when I click on them they are not shown and the "border" disappears. I tried to attch them them but the files are to large. Help!!

[idpnd]

What version are you on? Could you upload screenshots please?

Have you converted the charts yourself with libbsb?
If so, let us have a look at the template/header files.
It could be bad geo-referencing.
BTDT!! (been there done that)

I found VSPE (Virtual Srial Port Emulator) on Eterlogic - Welcome to www.eterlogic.com website
It is very usefull if you want to connect several programs similtaneously to one COM port. I use it to run OpenCPN AND PolarCom similtaneously from the same GPS and NMEA data sets. You may consider this link for the NMEA Instruments | Official OpenCPN Homepage page.

If Quilting is ON the *Show ENC text* button stops functioning.
If text is ON it remains on after Quilting is set ON
If text is OFF it remains OFF after quilting is set ON

This happens with both the 2005 and the 2009 set of CM93 charts

[petermoree]

When Quilting is ON and using a Cmap chart set (CM93 2005 set)
you can bring your mouse to the yellow bar at the bottom of the chart.
It then gives the following data:

Chartfile: D:/CM93/00300000/A/00300000.A
CM93 chart E 1/50000

However, only the second line changes when one moves from the North Sea to somewhere in the Pacific. The file location is always given as the first file folder in the CM93 subdirectory.

How can I find out in which file the program is really looking at a specific setting?
When I switch Quilting OFF the yellow bar does not release any data and the righthand top bar does give a file date but not a location.

In the 2.1.0 build 514 this has been solved

Hello,

EeePC 1001, W XP, OpenCPN 210 514.

I loaded all the RNC and all ENC U.S. without problem. But when I tried to unload all the RNC, forcing the reconstruction of the base, I had a crash.

In restarting the software, loading of ENC apparently ended normally and the display was set up correctly.


Best regards

Dave,

I spend sevral days testing (OpenCPN versus MaxSea and Tsunamis99). I tested charts on several locations where I once was such as Ducie (Pitcairn Group), Conway Reef and Minerva Reefs) and found a bug which can be reproduced as mentioned below:

Minerva Reef (south of Tonga) 23 39 S 178 55 W
On Google Earth clearly visible (I spent several days at these reefs in 1981)
In Tsunamis99 charts OK, reefs are visible at all scales
CM93 2010 very detailed ONLY when zoomed in correctly (OpenCPN version 2.1.0 build 514)
Before zooming in there is no indication whatsoever of a danger.
Charts of the reefs only show from True Scale 357300 (True scale 44600 gives the whole chart of the northern reef)
ALSO the detail charts at true scale 357300 ONLY shows up when the cursor is ON the exact position of the reef when zooming in.
Just zooming in does NOT result in showing up the detailed chart
I checked the same chart set with MaxSea 10.3.2.1
MaxSea has the similar display problems as OpenCPN which suggest that it may be a problem of the chart set.
However the following test shows a small but significant difference:

With the cursor exactly ON the detail chart zoom in/out and you get or lose the details.
With the smaller scale (= big area chart) you have no indication of the fact that a shoal or reef is there.
Put the cursor (AFTER zooming in) just slightly off the detail chart and zoom in/out again and you will see that the detail chart does NOT show up again (in OpenCPN 2.1.0 build 514)
With MaxSea you can zoom in/out without the cursor being in the right spot and still get the detail charts to show up.

The MaxSea is therefore a little bit safer with navigation, but this may be a repairable bug in OpenCPN.

However, for far greater safety it is necessary for the smaller scale charts (= big area map) to indicate by way of showing availabillity and location of larger scale detailed maps that dangers could be ahead.

The indication of the availabillity of largers scale details should show up on ALL levels of smaller scale instead of just showing up on SOME smaller scale
charts. At present it seems as if the detail map areas show up (in the purple outlined rectangles) only with scales appraoching the scale of the detail chart.

It would greatly enhance the safety of using OpenCPN if smaller scale charts ALWAYS indicate the location of available larger scale detail.

Kind regards

Peter

Hello Peter,

I have noted the same issue and tend to agree - some chart features appear very late at a level that would perhaps not be used in planning (although I would assume you navigate at that sort of scale).

However, you could try:

- increasing the CM93 detail setting (in toolbox or on right click - detail slider)
- if you turn on "show chart outlines" it draws red boxes where detailed charts are available.

[petermoree]

Details are always set tot maximum. The "show chart outlines" is also switched ON but this has no effect on showing chart boxes on the smaller scale (= big area ) charts.
I expirimented with the other vector chart settings without any succes.

Peter

[petermoree]

And it DOES make a difference if Quilting is set to ON. With quilting ON there are no chart outlines shown. With quilting OFF the chart outlines are shown only at certain larger scales but never at the smaller scales (= bigger area maps). Therefore the availabillity of the detailed charts can easily escape the attention of the navigator.

As I once spent a very scary 48 hours on the Minerva Reef, I have reason to worry about this.

[cagney]

I agree with much of this, but there is an other factor. There is no CM93 coverage of the Minerva area in C scale charts, only A scale. This makes a big difference in the amount of details that are shown.
In an earlier thread, the omission of Conway Reef from any CM93 chart has been discussed. Other areas of South Pacific also lacks proper detailed coverage. My own conclusion is to never trust CM93 for navigation(specially if only an A scale chart is available) without reference to other sources ( paper charts, raster charts, or info about the accuracy of CM93 in an area, etc).
For Minerva Reef there is proper coverage in small scale charts, available from Marco's NZ charts.

[petermoree]

The availabillity of chart outlines of ALL charts in ALL scales would solve the problem I think.

[petermoree]

I have tested this on 4 different PC's but cannot find the solution.

OpenCPN 2.1.0 build 520a with charts CM93 V2 2010

Under XP >>>> cardinal boys show up perfect
Under Vista >>>> cardinal boys show NO black topmarks or black/yellow boys.
All are completely yellow (boys and topmarks) which looks strange.

But this is not consistent (yesterday on an other brand PC and Vista the cardinal boys showed up correctly).


Whe trying to completely remove open CPN (via the control panel / software option) AND deleting files that remain under C:\windows there still seem to be files left. I do not know where they are but if I re-install OpenCPN it still has the *old* settings somewhere.

Does anyone know where they are located so I can test from a completely clean install?
