Small bug.

When viewing raster charts, if I zoom all the way out and them move my cursor down to choose a different chart, when my cursor gets over the colored selection bar for a chart, it jumps back to the center of the chart. If I move the cursor back down, it works the second time. It is totally repeatable. Just zoom in, back out to max, it does it again. It doesn't jump up if the cursor is over the gray area between the colored bars.

EDIT: Just noticed you don't have to zoom back in, just try to zoom back out again. Also, it only happens when using the scroll wheel to zoom.

Another small, kinda bug.

When I scroll wheel zoom in with "Wheel zoom to cursor" on, the bars at the bottom don't update to show the detail charts. If I then pan, they immediately show. Very minor inconvenience.

OK, this is more of a real bug.

When using raster charts, large scale, and further North, zoomed in, the pan doesn't work right.

Example is 50_1.KAP

Zoom in towards the edges of the chart. Try to pan South. It will behave differently depending on where you are on the chart. Sometimes it just quickly pans all the way to the North edge. The detail charts don't do it. And the charts in the lower 48 or in Brazil don't do it. I have only noticed it in Alaska, only on the large area ones. Sometimes panning left-right, it slowly works its way North, as well.

In exact same areas, cm93s and ENCs pan just fine.

dacust...

3 bugs:

1. Cursor jump to center on raster charts:
I cannot reproduce this. XP or Vista? Anyone else see this? More info, please
.
2. "Wheel Zoom to cursor" chart stack update. Noted, fixed.

3. 50_1.KAP:
This chart has very bad georeferencing coefficients embedded in it. I think it is an error by the chart producer (NOAA). Looks like a typo. Here it is in glorious detail:

WPY/3,1.2714083040e+004,2.6961271260e-007,-1.7590194810e+002,1.8652546170e-009
6.9495159630e-011,2.2049114840e+000,4.2542566690e-012,-2.8553754410e-013
-1.5201154140e-013,-2.9512686200e-002

The last number should definitely not be "e-002". Maybe "e-012"? Who knows....

I can fix it by manually editing the .KAP file to ignore this coefficient. Not a good idea in general.....

Do you see the same behavior on any other small-scale charts?

Thanks
Dave

Thanks. I'll watch the cursor jump and see if I got any more details, but so far it seems to consistently work like I said on all raster charts.

I had not seen it before Dacust speak of that but I have the same jump to center with the cursor.
I have Ubuntu Jaunty.

More about the jump :
It does that also once with CM93, but all the time when the cursor is going down 2 or 3 cm from its position, it jumps at the center and then go down. More difficult to see.
With raster chart, the more you wait after zooming out to go down, the less it does that.
If you go fast down after zooming out it jump when you arrive at the bottom, if you wait a little while, it jump at the center by going down, if you wait more it is normal !
And if you do that too much to try, Opencpn freezes for a while.

In terms of practical usage, I think it would actually be of advantage to permit further zooming in to follow the swaying at anchor closely; at maximum zoom, I can't really see the movements adequately (see below).

I haven't quite understood what "Automatic Anchormark" does. Does anyone have ideas regarding the implementation of an anchor alarm (under linux)?

The measure function is fantastic thanks! Maybe measuring tool & tracking could be marked as solved on sourceforge?

Good progress

I noticed this panning problem on 50_1.KAP before as well. I'm glad to hear its a chart error as it was kind of unnerving when panning up the coast.

Although, now that we can right click -> move boat here, I'm not having to pan up the west coast on 50_1.KAP. Thanks for that!

Currents in the pac nw are fixed as well. I'll be sailing with opencpn this weekend!

Will

Can someone explain the function of 'move boat here'? I was exploring the menus &, of course, clicked it to find out what it did. Well, it moved my boat to a new place on the chart & now I can't get rid of it. Tried plugging-in my GPS to see if it would return to my home port, but the icon stays in the wrong place. Am i just dense, or what?

I have been in touch with cartographic.com,sellers of a goof range of map types at very reasonable prices. They normally supply raster charts in 400 dpi size .jpg .gif .tiff but they would also be willing to supply .geotiff charts at a service charge of US$ 29.- This is on top of the standard raster charts prices at US$ 19.-each.
.
Is there a better site to obtain cheaper geotiff charts?
.
I understand that geotiff charts are required in order to produce BSB charts?
As the BSB format is licensed it would obviuously only be for 'personal' use.
.
I would be interested to hear from anybody working on the BSB conversion.
.
Perhaps,in the end it's cheaper to buy them ready made??
.

BSB conversion

Sinbad7,

You might want to hold off on purchasing any geotiffs for now. I'm still working on getting the bsb conversions to georeference properly. I'll open up a new thread about this soon.

Move Boat Here, etc.

Jerrymc, and others....

Move Boat Here: This function, well, moves the boat "here". It actually is implemented by simulating one( and only one) position message from the GPS.

The function can be useful for planning purposes, as the Status Bar "From Ownship" report will be an accurate reflection of the brg/range from the cursor to the ship icon. There may be other uses..... Manimaul?

If you have a real GPS attached, properly configured, then the Chart Title block in the upper right corner of the Toolbar will be pale green, and the ship icon will immediately jump back to the acquired GPS position.

Thus, "Move Boat Here" is of no practical use with a real GPS attached. But there it is anyway.

Other ideas for similar function are encouraged. One of our goals is to make stuff so intuitive that the combination of software and cognitive user together just do the "right thing", especially under high stress conditions.

Comments?
Dave
