Credit goes to Jon, who did by far most of the work regarding
mass-imports of obstruction databases.
There's just one minor drawback hidden in this concept: Contributors
are slowly but steadily replacing the respective 'generic' models in
use as placeholders for aeronautical obstructions - which is Good
because it makes our Scenery nicer. Even though we may assume that
these customized models are being designed closely aligned with the
original building, probably not all of them are matching the criteria
of having the 'official' height as accurately as the generic ones did.
If we make the highest spot of these models align with the authritative
elevation, some of them may end up hovering above the surface if the
terrain elevation is too low :-)
If anyone is having a solution at hand, feel free to contribute. Even
though some of the customized models have now been adjusted to the
current terrain elevation, we're still having backup copies of the
'original' data.
Cheers,
Martin.
