AvNav implementation in OP2

[Littlechay]

The quilted view is a problem.

@Littlechay: do you really also see this on Windows? I made some quick tests with a subset on Windows - and do not have this issue at all.
It seems to be related to some new GDAL version - but should not be there on Windows.
When you use the chart just be sure to copy all parts of the created gemf to the AvNav server. Uploading inside the app will not work for multi part gemf.
But I guess I will change the size limit so that you will get bigger gemf's in one chunk.

---

Ok, after some final checks:
1. I guess the problem with the quilted view should not be there for you except if you run a GDAL version between 3.0 and 3.1.1.
2. If you run from the GUI there should be one gemf at the end
3. The remaining problem are charts that cross 180 - but the set seems to be usable after conversion


Best regards

I'm not sure about the quilted issue on windows.. I meant that it would be a problem in general. I have not managed to produce a set to quilt yet. 

I stripped the BSB files etc out as you suggested and tried to run a conversion on the whole set and got this output in the converter window.

I have attached the .vrt files in a zip
and the log file (delete the .doc on the end )
