I would be very interested in any test done on using Bias values
I'll have a look into it first thing in the morning, I used Global Mapper to figure out the offset and then manually dragged the building to it in ADE and almost got it spot on.
There may be a different option that could be implemented in ADE where instead of bias values it takes the heading info and calculating meter offsets from lat/lon co-ordinates. i.e. the user knows the offset distance in meters and inputs it then it calculates the lat/lon offset from that based upon Lat/Lon pixel size. I have a chart that I could give you that might help with calculations.
Another suggestion that would significantly speed up airport scenery design would be:
a) ability to automatically build a runway 'link' based on the actual runway data, i.e. places nodes in the middle of both ends of the runway (or blast pads) etc. This would save having to find the midpoint of both ends of the runway and make it easier to prep for cross taxiway links.
b) if a) were to be implemented then it would also be good to offset the runway links left or right by x.xx meters as you'll notice on real world airports the taxiway lines tend to start just left or right of the centerline.
c) create (x) number of parallel taxiways based off "runway link", as most taxiways are parallel to the runway creating master taxiways with the same heading would be a very rapid way to build an airport.
d) if (c) were implemented, being able to choose a taxiway link and copy it and paste it and rotate it 90 degrees would also be helpful. If (c) and (d) were implemented then all you'd have to do is add nodes at the intersections of the taxiway links.
e) import of shp and kmz/kml line, polygon and point data and generate taxiways/airports from that data. I have a little program that can kinda do that with KML files that Jim Keir wrote a while back but we never polished it up, I could give you that code.
f) manual placement in lat/lon for Slope/DME data in ILS localizer dialog box. can this be accomplished via the pro key and manual XML editing? some airport data has the lat/lon of the glide slope, DME and localizer transmitters. Right now you can manually drag the DME box to it's real location but I'm not sure if this affects it's actual placement in sim?
g) as mentioned in an earlier post by someone reading of .tfw, .jgw, .ecw or .mcf image lat lon data. (.mcf is easiest as it has the extents)
[edit] one more suggestion h) design parking with a top down view of a particular aircraft model shape (i.e. a 727, a 747 etc) it could be a cut out of a standard 3 view top view, and maybe eventually a red dot on that overlay aircraft for where the door should be located. Would help lining up aircraft with Jetways. The other option or co option would be someone figuring out standard T offsets for each type of aircraft and then quickly choosing t offsets based upon aircraft type
okay one more suggestion for a future release. i) a set of vector poly overlays that contain runway markings and numbers (according to FAA, ICAO, Aussie CAA specs) that can be placed on top of the scenery to add custom ground markings at an airport. I'm not sure if the default markings would override a ground texture poly though.
