FSX How can I batch resample hundreds of aerial images ?

[Flywell]

Hello all,

After encountering several timeout errors when downloading and processing aerial imagery with FSET, I decided to skip the “resample to BGL” step to gain processing time, thus avoiding the fatal timeout error.
Furthermore I thought this would be an opportunity to try out some colour balancing with Metrix before starting the resample step.

Now I have hundreds of BMP images (including seasonal changes, masks and thumbnails), plus their pertaining .INF files, as well as TXT files related to masks.

Is there a convenient way to perform resampling as a batch process for all those files, without having to manually add detailed information for each of those "hundreds" in the INI file intended for “resample.exe” ?

Thanks in advance for your help.

Chris

Hello, not answer your question but Im interested in learn how to make a matchmaking satellital pictures, its a hard work but I read with Metrix its more easy, do you have a video tutorial to show us how use this tool? Thanks

Hi Chris:

You may wish to study the methods Arno uses via CMD mode (aka "DOS") batch processing ...cited / linked here:

Hello,

Here's where I learned about METRIX : https://www.fsdeveloper.com/forum/threads/gimp-question.428948/
and here's a basic tutorial on how to use it : http://www.jnrubin.net/psi/instruc.html
As you will see, it needs two image files to perform the balancing process.

At the time I started this thread, I was not aware that I first would need to balance colours within single tiles/files,
before using METRIX to match a set of images.

So using Photoshop, I started to extract the non-matching areas and save each as a separate image, then perform the balancing steps,
and later on re-assemble/blend the patchwork properly. But honestly, this is a lot of work : more than I can afford to do now...

Meanwhile I considered downloading an updated set of images, then mix both sets to replace the 'faulty' tiles.
Hopefully this will give a better result

Hello Gary,

thank you for your reply.

I'll have a close look at all these items and surely find some valuable information to reflect on

Hi Chris:

If this is for a personal project rather than a commercial one, you may find the current imagery for ex: EDRO in SBuilderX v315 via the Google_api3_Satellite tile server to be rather well color-matched already.

https://www.google.com/maps/place/49°01'54.0"N+7°59'27.0"E/@49.031667,7.988639,454m/data=!3m2!1e3!4b1!4m5!3m4!1s0x0:0x0!8m2!3d49.031667!4d7.990833


IMHO, since most photo-real in that area is likely to be largely obscured by Autogen, you might only need to adjust the color palette to match that of FSX / P3D, rather than to be as detailed as Metrix allows (...but at a cost in manual labor).

This could likely be done via a semi-automated procedure using Photoshop's batch processing feature:

BTW: John Venema of OrbX discusses making seasonal textures:

PS: Even if you have licensed imagery that needs 'some' color matching, you could set up a batch routines to apply certain presets that may be required based on visual inspection in a preview mode as you view adjacent imagery tiles.

I hope this info might also prove helpful as you consider ways to reduce some of the work-load for your project.
