As can be seen, Shannon airport doesn't exactly line up with MegaScenery Earth's Ireland photoreal. Do i need the payware version of Airport Design Editor to move it somehow?

Not sure if it's worth me buying a payware Shannon airport, but if i were to buy the airport, would that version be better aligned I wonder?

Thanks.

Yes, to move a whole airport, you must have the "pro" version of ADE. 

That said, looks like more problems than just moving will solve. 

 

Well, that is the stock Shannon airport, but I've also tried a couple of freeware ones which have similar offsets... 

What do you mean by "more problems"? 

It's been about four years since I last created my one airport.  If I recall you need to put base layer or polygon underneath to block out what is otherwise there.  Then the replacement airport sits on that polygon.

Different parts of the airport would need to be "moved" different amounts, the objects are not all off by the same distance/angle. 

The taxiway/runway intersection towards the top of the photo appears to differ significantly between the photoreal and AFCAD.

The taxiway/apron to the left of the runway doesn't seem to match well at all. 

These are the biggest things I noticed.

I've created several airport sceneries for FSX (published a half dozen) and found an easy way to check the accuracy of objects (e.g. runway ends, taxiway intersections, apron corners, etc.) is compare what you get with slew mode in the sim (displaying coordinates) with Google Earth or Google Maps. Many freeware airports are simply amended/augmented copies of the default airports in the sim. Thus, they carry forward a lot of positional inaccuracies that were in the original, default AFCAD.

Hope this helps.

If I were to get the pro ADE then I'd "just" move the entire airport down and to the right (when looking at the photo) the get a "point of best fit" as it were and then proceed from there. After getting my head around the manual 

Frank - I know what you mean about ground polygon - that would certainly block out the photoreal, but seeing as the actual airport doesn't appear to line up with a real world photo it's kind of ignoring the real problem I think. The polygon ide does sort out the problem of plateaux airports quite nicely though! One might argue that the photo could be distorted, but it looks pretty uniform over the entire area, especially given that it's part of the whole of Ireland.

What I can check easily is the placement of other stock airfields... 🍻

Thanks gents!

@HighBypass Before you do anything else, I would use the slew/Google technique to see which of the presentations is more accurate. 

Most likely the photoreal is more accurate. However, I have seen freeware sceneries where the photoreal base was moved to match the AFCAD. 

Good luck with your exploration.

Hi Mark,

Unfortunately I can't really tell you whether it would align as I do not use Megascenery Ireland, but just to let you know, if you were to go down the payware pathway, that the only payware scenery available for Shannon is from Eiresim and this is showing its age a little as it dates from FS9 days and seems to have been minimally modified for FSX. In particular, the textures of the buildings, etc are not quite up to the standards which we know are achievable with many FSX airport add-ons. In saying that, perhaps I am being a little too harsh on it, as it really is not bad and, although it portrays EINN as it was in the mid 2000s, it is a pretty accurate rendition of the airport as it was then and reasonably priced. The other thing to bear in mind is that, although their products are still available, Eiresim itself seems to have disappeared off the face of the earth, so in the unlikely event that you would require support I am not sure if it would be available from them.

I do know that the stock AFCAD data for Shannon is contained in the file APX45130.bgl which lives in the FSX\Scenery\0501 folder and, although it might be a bit of a longshot, I guess you could try temporarily deactivating this to see if it resolves your issue?  However I cannot be sure whether deactivating it might cause other issues so make sure you keep a backup!

I use Eiresim EINN with Orbx Ireland and, after deactivating a couple of Orbx files, it works very well. However, although the Orbx scenery for the area is visually very nice and reasonably accurate (if you use your imagination!) it would of course be nothing like as accurate as Megascenery's photoreal scenery. I used to fly into EINN a lot in the real world as a young lad, as the nearby airfield where I learned to fly many years ago did not have refuelling facilities available in those days requiring a 5 minute trip up the river for Avgas, so I am very familiar with the area and, for this reason, I did use photoreal scenery for Ireland in my FS9 set up. I haven't done that in FSX though because I found that photoreal scenery tends to have a cumulative effect on VAS usage so I opted to use the Orbx scenery for the various countries of the British Isles as a compromise. Hope you can get it sorted!

Thanks for the info, Bill! 

I don't know if an EINN payware version would be better aligned, but I do know the default scenery isn't aligned with the airport's actual coordinates.  Inserting a Google sat image as background to the default EINN shows the default airport isn't aligned with the real world.  Comparing what I see with your image shows the MegaScenery Earth's Ireland photoreal is aligned with the real world.  I would upload the image here, but avsim isn't letting me for some reason.  If you're still interested, I use ADE and move the airport for you.  Please let me know.  

 

Hi SAX - yes please if you would be so kind, thank you! 

A great bit of work @SAX702 placing the stock Shannon where it should be and a couple of tweaks also! Thank you so much! 🍻

forgot the images!

@HighBypass, glad you like it.  Looks good with the MegaScenery Earth's Ireland photoreal scenery.
