Grib Enhancements

No, the arrows are OK, as you point out. I meant the numerical value displayed, for currents only.

ah of course.. fixed in git now

Branch Sean/grib_enhancements - Grib_pi (grib_enhancements) complied. Copied grib_pi (2 minutes old) from ...opencpn/build/plugins/grib_pi/debug to be just under ..plugins. Then ran MSVC debug. It works. Tried running most of the grib files I had, some current, waves, pressure, wind. Did not try seatemp or clouds.

A few breaks due to timeouts, but just continued. Seemed reasonably stable.
Have compiled a release DLL (should run in windows) and now attach it for others to test and try out. Screen shots to follow. Thanks Sean. It runs very nicely!

Perhaps there is one small control that would be helpful. How to control the intensity of the colored overlay so that we can adjust it to see the underlying wind or current arrows? Maybe I am overlooking something here...

[rgleason]

Here are various screenshots. Currents, Pressure, Wind,

[rgleason]

Here is the most recent which fixes the little bug with the horizontal scroll which obscures reading the current grib file.

Incorrectly Posted in Wx-Rte thread Post #198

Do these work in release mode? All of them work for me. Maybe I need to try with wx2.9 to get the asserts

Using the grib_pi.dll published above, in Opencpn 3.2.0 I get the following:

solent_Whole_Domain.grb Opens, no data field shown, hit play...bombs and removes the plugin by turning off enable.

WW3_DIRSW_HTSGW_Whole_domain.grb.bz2 Opens, no data field shown, hit play...bombs and removes the plugin by turning off enable.

WW3_DIRSW_HTSGW_Whole_domain.grb same

OSCAR-bdc9be2a-CUR-SEATEMP.grb Opens, no data field shown, hit play...bombs and removes the plugin by turning off enable.

Also bbs2010.grb Opens, data field is different than normal, hit play... bombs and removes plugin by turning off enable.

Sean these files are in the Opencpn/Currents-Grib folder that I shared with you.

I have not tested all of these files, but I believe you had them all working in an earlier version, because I tested them before.

I'm going to GIT the current version you have available and try it in both Debug and Release.

[rgleason]

Okay, I done've GIT FETCH and GIT PULL with for grib_enhancements. Compiled, copied wx-rte and grib to plugins.

In Debug mode I had a number of breaks with various files listed. Call Stack is copied.

In Release mode using Opencpn 3.2.0 the Grib plugin was stopped immediately and had to be re-enabled when I tried playing or step frame solent_Whole_Domain.grb and WW3_DIRSW_HTSGW_Whole_domain.grb.bz2

The other files seemed not to do anything, but I noticed that the Date drop down only shows one date, not a series of dates!! I could generally select to try another file, unless it failed completely as abbove.

I don't think the grib plugin is handling a slightly different date and time format as it has in the past.

[rgleason]

I have updated the enhanced grib_pi.dl , weather_routing_pi.dll and opencpn.exe for weatherrouting, based opon a git fetch and git pull from sean's website.

Okay, I'm going to post the link in hopes that it will work for the majority, keep in mind that Nortan may complain and remove the file. You should do what you think best. Perhaps we'll find a better way later if this proves to be a problem.

Click here and you'll see the files. Then click on each file and download it.

Let me know if there are problems.
Sean I think I can fit into your schedule, lets hope we get some other guys testing this pronto!

From Post #114 the files at this location have been updated.

NOTE: The grib_pi.dll will work standalone with Opencpn 3.2.0 and others, however weather_routing_pi, requires a special version of Opencpn, which is in the opencpn.zip (opencpn.exe) along with creation of a plugins/weather_routing/data/ directory that contains weatherroutingInformation.html file and the grib-pi.dll in this download.

[seandepagnier]

I think the problem is those files only have one date which was the source of some bugs. So I think I need to disable the play and step buttons in this case. Maybe even hide the play and slider timeline

[rgleason]

Sean, I am not sure those files have one date. I had the impression that at least some of them had multiple dates / times. Can you determine that somehow?

[seandepagnier]

I fixed a lot of timeline issues, the plugin should work much better now

[rgleason]

Sean, GIT grib_enhancements branch and weather_routing_pi and built OK.
Started Debugging, Enable plugins, then Select Grib plugiin, with no Grib data no Play,
When select small wind multi frame grib it works fine, play etc.

However there is a problem with Pressure Isobars and having the right setting for that. When you select a grib which has Pressure AND you have the Pressure Isobar checked under Pressure AND the Isobar Spacing is tooo small, the computer gets overwhelmed, fans speed up, cpu use increases, and the Building Isobar popup can remain up running. (It would be nice to be able to shut that down by Canceling in the upper right X box with a mouse click (everything gets very sloooow and unresponsive) so that the Isobars are discontinued when this happens. --Somehow I had Isobars set at 10 instead of a larger number like 500 (probably a change from millibars to inches or something).

Now I think I understand the problem... I had it set for Inches, where did the inches setting go? Now only mmHG and millibars mercury..

After messing around some more with Pressure Units, perhaps I had it set on Millibars at 10 and somehow it got changed to mmHG causing the problem.

Is there a way to adjust the size of the Numbers and the Number spacing in Pressure, they seem to be two different things with double number overlays!!
Checking numbers causes another overlay of numbers.

- No, now I think the "Numbers" check is for a grid of numbers not associated with isobars.

- So now I think it would be helpful to have two other settings for Isobars - size of numbers and spacing of numbers. Or perhaps there is someplace to set these?

[seandepagnier]

No place to set those I didn't implement most of the millions of possible options. Source is open...

Anyway.. yeah.. it should let you cancel isobar generation if it is taking forever. Also I could probably optimize the isobar routine to run about 20 times faster.. but I'm doing other stuff.

[rgleason]

I didn't check alll the files that were giving trouble. Some of ones that were a problem are now shown as single frame with Play button greyed out. --Are you sure that these only have a single frame?

Other ones still break, but I don't have to re Enable the plugin, I just have to Browse to the Grib directory again. I don't know what the problem with these files is, perhaps a different format, or perhaps they a badly formed? I will try them in several other grib viewers to find out.

Anyway here are some of them from the Grib-Current folder. Did not check them all.
