FlightGear - LICP Airport - What's wrong with the coordinates?!?
I have an aerial picture of airport LICP (Boccadifalco, Italy) with UTM33N coordinates which could be very usefull for correcting FGFS' LICP airport geometry, whose level of details is relatively poor. I made a .xml FGSD Map file out of it.Now I have a problem because the aerial picture I have should have correct coordinates (the web site that publishes the pictures is a Government Institution) but as soon as I overlap it to the scenery data in FGSD, I have it displaced by by approximately 550m (Fig.2).
As you can see the bottom-right corner of the runway has different coordinates.
- www.atlanteitaliano.it : E 013:18'52.3 - N 38:06'36.1
- fgfs scenery file: E 013:18'51.3 - N 38:06'18.2
I don't know if it's the aerial picture's fault or the FlightGear airport file's fault.
I think it's the airport file's fault but I am not shure. You maybe have other tools and knowledge for determining that. Any hint? I have to choose between thinking that FGFS airport files are not very correct or that a Government Institution does a bad job (which, even if I doubt, is still possible).
