The OpenAIP support has been merged yesterday in the master branch.
The NOGLIDER definition of OpenAir remained, in order to don't change the existing airspace definitions.

For who is interested I wrote an open source airspace converter tool from OpenAir or OpenAIP airspace files to KML files to be shown in 3D with Google Earth. It is also capable to output back again in OpenAir (attempting to recalculate arcs and circumferences), in PFM "Polish" format, as file .mp, for software like: cGPSmapper or directly as file .img for Garmin devices obtained using directly cGPSmapper.
Written in C++, it works from "command line" on Linux, but in order to make this tool immediately easy to use, it is also available as Windows application with graphical user interface.

All the info here: http://www.alus.it/AirspaceConverter/

Wow! This is a very nice tool!
I've been looking for this a long time.
Understanding the airspace structure becomes a lot easier this way.

After uploading OpenAir files of The Netherlands and Germany the program produced 29 error messages like the one below:
ERROR: unable to parse line 4577: AC RMZ
Also AC UNKNOWN isn't recognized.

Thanks for the feedback I will try to reproduce the error and fix it this weekend.

Beware that this tool is relatively new so there will be other errors...

BravoLima, can you tell me from where you got those OpenAir files that generate errors?

Check this dropboxlink for my airspacefiles: link removed.
These are selfmade (ZCH_230616-1.txt) and modified (DAeC_310316-4.txt) files.

AirspaceConverter doesn't recognize:
- Radio Mandatory Zones (RMZ), new in LK8000 v6.0a -> 28 RMZ's in total = 28 errors
- Airspace Class UNKNOWN in LK8000 -> VOR/DME approach specified as class unknown = 1 error
(unknown can be any name except from those already specified in LK8000)

Thanks for sharing the files.

As promised, I fixed the two problems plus other bugs I discovered along the way...

The new and fixed version 0.0.1.2 is ready and downloadable from the same place.

BravoLima, thanks for your interest and if you find something else let me know.

When I will find the time I would like to make the colors for each kind of airspace configurable.

This possibility exists in Google Earth already and is easy to carry out. Therefor this color adjustment may not be necessary.

What also would be useful, is the ability of showing waypoints in Google Earth. Waypoints are saved as cup-file but you can edit the file with MS Notepad. (See: http://www.keepitsoaring.com/LKSC/Downloads/cup_format.pdf)

The latest version 0.0.1.4 is attempting to parse also SeeYou .CUP waypoints files in order to display them as well in Google Earth.

The HSI I developed in LK8000 (as agreed with Paolo) assumes the waypoint coordinates of an airfield as the exact center of the runway, then it uses the orientation to calculate the alignment and the length to calculate the descent path angle to the head of the runway.

So for this reason, for all the airfields, I wanted to draw the runway perimeter knowing center position, orientation and length in this way the people maintaining CUP files can try to easily correct any eventual wrong positions, length or orientation simply comparing the rectangle drawn in GE with the actual runway. The way the converter displays the runways in GE is exactly the same as LK8000 is interpreting the same info for the HSI screen.

Hi All,

I just wanted to let you know that recently I introduced several improvement to the converter.

I made a Qt user interface to make it more portable, so now the UI is also available for Linux, also as Debian package, I created an APT repository for it.
So it can be easily installed also on Nimbus, the LK8000, Debian based, development virtual machine.

Now it is also able to read KMZ/KML files as input, this feature is based on the Austrian airspace file made by Austrocontrol so it should still be tested with KMZ files from other sources.

The conversion to Garmin IMG files has still to be improved.

Hi All,

I just wanted to let you know that I released a new version of AirspaceConverter: 0.2.6

Thanks to the help of a new contributor: Valerio Messina we added some new features, which the most relevant is the possibility to filter the output on a latitude and longitude range.

Thanks to Valerio we have now also DEB packages for Ubuntu 16.04 in our repository.

If you find anything not working properly please let me know.

Al.
