That is fast

Yes a GPS is connected and working.
Attached a screenshot with the cursor above Liverpool. According the statusbar the distance is 298 nm. According PI 11000

It may work in Linux, but I think there is something amiss for the Windows version.

I'm having the same problem under Linux.
Zooming in and out again does help as a workaround.
I already tried to add a RequestRefresh after the JumpToPosition call, but that didn't help.
More likekly to be a bug in the implementation of JumpToPosition in O I guess.

Dirk...
Yes, the problem is in the core, most likely related to the brutal change of position and scale that happens during this operation vs. OpenCPN trying not to do unneeded work, which works fine during normal panning/zooming. I will have a look into it.

Hi all...
The second testing release of the plug-in is now available for download from PlugIns | Official OpenCPN Homepage

The changes included:
- Update the bundled sqlite to 3.8.6 and wxsqlite to 3.1.1
- Hopefully work around the OpenCPN crash on exit on Windows
- Implement human readable and localizable texts for chart feature names
- Implement select/unselect all in the features dropdown
- Implement Lat/Lon formatting according to OpenCPN core settings
- Prevent zooming to scale 0
- Fix the distance calculation
- Improve the performance of database operations

So far this should be all the stuff I'm able to address in the plug-in itself without touching the core program, let me know if it works as expected.

Also, it appears to only search area near the boat location as well as wherever the viewport and sometimes outside the viewport. I would prefer an option for a distance from ownship, or viewport. I am getting results from locations far from the viewport and ownboat.

The longitude shown is 0-360 instead of 180 E and W, and latitude doesn't show N/S.

More later.

Pavel,

As Sean already noted the longitude has a problem. I think this causes also other problems.
Distance across the greenwich meridian are wrong. (or right if you would travel around the globe)
The "Show on chart" also seems to work fine aslong I stay on the eastern hemisphere, but goes (almost) blank with a jump over the zero line.
Lat long much better readable now.
Object names

Edit
I added a

if (lon > 180.0)
        lon = lon - 360;

at line 712 and this does the trick for show on chart

Solves just the symptoms, not the cause, which is the chart data. We better fix it while saving the objects in the database - coming in the next version.

Underway so only a quick check.
Seems OK now in git.
At installing I get an error

-- Installing: /usr/local/lib/opencpn/libobjsearch_pi.so
CMake Error at plugins/objsearch_pi/cmake_install.cmake:52 (FILE):
  file INSTALL cannot find
  "/home/dirk/Development/OpenCPN_master/OpenCPN/plugins/objsearch_pi/data".
Call Stack (most recent call first):
  plugins/cmake_install.cmake:40 (INCLUDE)
  cmake_install.cmake:192 (INCLUDE)

But everything seems to work fine.

sugestion:
After a show on chart, the chart jumps to the position. but this position is hidden behind the obj_search window. Is it an idea to close the window after "Show on chart"?

Nohal, great job. After some polishing, this will become an awesome tool.

Is it possible to make a function which iterates through every installed chart, so the database will be populated? Maybe you could put it under plugin settings, and write a small notice it might take a very long time.

Buy a zillion coffees and run OpenCPN with -unit_test_1 command line parameter...
I'm still not convinced the database with all objects from my worldwide chart portfolio is a good idea (I did it during testing, of course)

Thanks, unfortunately /unit_test_1 seem broken on Windows. And I am currently out of coffee and Linux.

What seems broken on it? Works just fine for me. If you expect it to scan the whole world of CM93 charts, then no, it will not do it.

Is there a simple way to scan the whole world for CM93? For S57?

[nohal]

S57 - unit_test_1
CM93 - no
