It is essential to NOT scale imagery or change total pixel Rows / Columns ...to keep existing Geo-referencing correct.
IIUC, you are trying to change the size of ONLY a road within the photo-real imagery.
If so, this can be done in ex: Photoshop with a copy of the original imagery file by selecting the road with ex: the Magic Wand tool, copying it, and pasting it into position as a floating selected object, and re-scaling that object ONLY.
That scaled floating object can then be 'merged' / 'flattened' into the background image.
Please let me know if I have understood your goal correctly.
Could you please explain what you mean by: "the image is out of proportion in comparison with the rest of the scenery" ?
By "rest of the scenery", are you referring to surrounding artificial land class tiles provided by OrbX FTX Global ?
If you would please post a screenshot of where you are seeing the mis-match of imagery proportions you reported above, I would be glad to offer more more task-specific observations / suggestions ex: on how to better integrate your custom photo-real land class imagery BGL into the underlying surrounding artificial land class tiles provided by OrbX FTX Global.
What I'm trying to say is the image looks too small, so objects like the hanger look too small compared to the glider. The hanger should be roughly x2 the size. This also makes the airfield smaller than it should be. BTW I have now blended the image, looks great!
As you can see the hanger is too small for the glider so it looks out of proportion.
Also, here is the road. The road provided by Orbx vector is the correct width, while the photoreal image is too small, about 1/2 the size.
I'll have to think about this scenario for a bit before I reply with a suggestion to try, as I have not yet encountered this apparent inaccurate 'sizing' / 'scaling' issue with imagery from any online tile-servers ...processed via SBuilderX.
Did you manually edit any Geo-referencing or pixel dimension parameter values in the *.INF file before compiling ?
BTW: Which user aircraft 'glider' are you piloting in the FS screenshot above ?
< Yup... I want to verify the wing-span size to identify what imagery sizes we are seeing there locally in FS at run time >
GIS application in ESRI World Imagery shows same size as Google Earth and SBuilderX in 'VirtualEarthSatellite'.
The FTX Global vector is AFAIK, intended to be accurate to the real world for Roads.
FTX Global land class textures are apparently not accurate for this location at this time.
I would suggest that you consider expanding your custom photo-real imagery coverage area outwards so the Blend Mask can be aligned with edges of Roads / landmarks in OrbX Global Vector CVX BGL data set that more closely match the imagery of 'VirtualEarthSatellite'.
Otherwise, you can 'Exclude' OrbX Global Vector CVX vector BGL (local) QMID-11 contents, and replace it with your own custom Roads, so that they align with the imagery of 'VirtualEarthSatellite'.
Feel free to let me know what your thoughts are with regard to this, as there are other options which might be considered as well.
FYI: I am making a "quick-and-dirty" 3D model of the hangar in question from Trimble imagery in Sketchup to inquire into the 'scale' issue.
I will post some results on that in a while, in this same thread.
