Lately I'm controlling egll ground. I found a sectorfile with a good ground layout. There are also good sector file of england center. I'm looking for a file with both however. As I could not find one i merged the two files together which worked out pretty good. One minor problem however is that the ground layout is a little bit to much to the south ( t was already in the original file).
Is there any easy way to correct this? I tried editing the numbers by hand but that takes for ever and it is nearly impossible to track errors.
