• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Hello :)
To train myself for future photoreal placement, I've downloaded some orthoimagery at USGS TNM, and I need help to know how to transform the images to a Photoreal scenery. (the images are not for Nouméa or Wallis&Futuna, it is for me to learn how to make photoscenery, maybe after, I'l make a scenery with it)

What I want you to teach me:

1) What are JPG2000, how to use them?

2) Ho to place it on FSX (correct place :P)

3) Seasonal and night textures

and if there are other things to do, you can help me too :)

JPEG 2000 is an image compression standard that was hoped to replace JPG. Although it was developed in 2000 very few applications use it. I understood Adobe used it but it's now a legacy option plug-in.
 
The nice thing about the JPG2000 format is that it can also contain geographical information (so contains information where on earth the image is positioned). Hopefully that also applies to the image you downloaded.

If that is the case you can try to convert it to GeoTIFF using the GDAL tools (check OSGeo4W to get those tools). If you have the image as a GeoTIFF using WGS84 coordinates, you can very easily use resample from the SDK to turn it into a photoscenery BGL. You might have to reproject to WGS84 using gdalwarp.

Seasons or night versions of a photo scenery are basically another set of images that you compile with resample into the same BGL. So then you would have to use some tool to edit the imagery and make the night or season variant.
 
I think I got started in creating photoreal scenery by googling "FSX How to create photoscenery" (literally). From there I read every tutorial, post, and YouTube video I could find - can take weeks or even months if you are serious. Yes, there is that much information about the subject over the years. I would suggest the same as it gives you a good foundation. Just a suggestion.
 
Wow; thank you all for fast reply :)

I'll try :)

EDIT: Where and how to download GDAL,? :)

Sorry for the silly question but is Gdal and FWTools similiar tools. FWTools is what I use to backup the data from geotiff before edit in any image editor
 
Yes, but FwTools is no longer maintained, so it contains a much older version of GDAL.
 
Thanks for answer, this is what FsxKml work with too, and having learning this two command listgeo to backup the data to a .gtf file and geotifcp -g to resotore the data to the geotif raster is enough.
 
Thabks arno :)

Tejal, I confirm that FWTools is no longer available; I'v' tried to get it yesterday :)

You better get GDAL from OSGeo4W.

http://trac.osgeo.org/osgeo4w/

Then you can use the OSGeo4W shell to run the tools.

Hi Arno:

Speaking of GIS utilities which are "older" versions, do you by any chance know if the above cited OSGEO4 contains the "newest" GDAL components ...as discussed in the context of this thread: :scratchch

http://www.fsdeveloper.com/forum/threads/watermask-from-shapefile.433999/


Thanks in advance for your clarification on this ! :)

Yes, the OSGeo4W build is frequently updated with newer versions of the tools. So it has the latest GDAL version quite soon usually.
