How to change a photoreal images 'scale' (increase size)

[Ols500]

Hi I would like to upscale a photoreal image to fit the road size. Is there a parameter where I can upscale the image?

Thanks, Ollie.

Hi Ollie:

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.

Hi Gary, I actually mean the image is out of proportion in comparison with the rest of the scenery. So yep I would like to actually scale the image.

Thanks.

Hi Ollie:

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.

Hi Gary,

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.

Thanks, Ollie.

Hi Ollie:

I see what you are referring to now.

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 >

Hi,

"Did you manually edit any Geo-referencing or pixel dimension parameter values in the *.INF file before compiling "

No I did not this is my INF file:

I am using the "K21" roughly a wingspan of 17meters.

Hi Ollie:

I will check a few things relative to Southdown in Google Earth, SBuilderX and a GIS application for a few minutes.

Hi Ollie:

The same appears to also be true for the hangar size; are you certain that hangar is used for a non-disassembled glider ?

What are the Geographic coordinates of the "mis-matched" road sizes seen in the bottom image that you attached to your post above ?

Yes I am certain as I go the club.

Do you mean long/lat?

Yes I am certain as I go (to) the club.

Hmmm... I will have to do some further inquiry on this "scale" scenario via SBuilderX and my GIS application for a few minutes.

Yes, please; Geographic coordinates in Latitude and Longitude ...from either SBuilderX or Google Earth.

50.919948, -0.465599


Those are the lat and longs

Hi Ollie:

GIS application shows same size as Google Earth for the above cited Southdown Glider Club hangar in ESRI World Imagery.

Which tileserver did you use in SBuilderX for your custom photo-real imagery land class BGL shown in your attached screenshots above ?


Also, please confirm whether you have more local add-ons than just OrbX FTX Global Base Pack installed.

Specifically, I'd like to know if you also have installed:

OrbX FTX Global Vector

OrbX FTX Global openLC Europe

OrbX FTX EU England

OrbX FTX EGHR Chichester / Goodwood Airport

Flight1 Scenery Solutions Ultimate Terrain X Europe

...or:

Any other 3rd party (payware or freeware) add-on providing land class textures and/or CVX vector Roads that cover this local area.

GaryGB

 

[Ols500]

Hi Gary,

OrbX FTX Global Vector

OrbX FTX Global openLC Europe

OrbX FTX EU England

All of those.

I used 'virtualEarthSatelilte'

Flight1 Scenery Solutions Ultimate Terrain X Europe

...or:

Any other 3rd party add-on providing land class textures and/or CVX vector Roads

I only use Orbxs' stuff.

Thanks.

Hi Ollie:

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.

This seems like the best option

Oh wow, thanks a lot! I have been planning to create some 3D models but got no idea how to. Is Sketchup free? If so is there a tutorial?

Hi Ollie:

I am basing the "Q+D" Sketchup 3D model of Southdown Glider Club's large hangar on this image from their website:

https://www.southdowngliding.co.uk/wp-content/uploads/2019/05/hangar-1-1030x639.jpg

I have estimated that hangar's real world size to be: 15 Meters Wide x 25 Meters Long x 4.5 Meters Height at roof peak

Apparently the Glider bays are on the sides, each with double sliding doors for each adjacent pair of bays ?

[EDITED]

Info on another website stated the intended Southdown large hangar capacity was 18 gliders ?

https://uk.linkedin.com/in/craig-lowrie-17909510


That would be 2.7777777777777777777777777777778 Meters for each Glider bay width ...along each of the (2) hangar sides.

IIUC, that means Glider wings must be stowed before backed into bays.

I'm not yet sure how that correlates with structural supports shown in the above image ...and this one:

[END_EDIT]


More info to come shortly on Sketchup.

Yes this is correct

Thanks, Ollie.
