• 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.

How do I create a photoscenery?!

I bet it's been discussed a million times, but i don't even know where to start, what progs i need and so on.

The thing is:

I have a 0,5m/pixel satelite photo of my airport and the sourroundings. But I don't know how to put it in FSX...

I have read the SDK but I made me just more stupid ... can somebody help me?
 
Hi There

Hi There.


If you have the image, all you need is a good program which can do the rest for you easy.

This is payware, but I bought it my self. I have not used it just yet, but many which make photoreal scenerys like the one you are talking about, use Terrabuilder.

Terrabuilder does the work for you. It is almost follow steps and click next.
There is even a good guide on the website.

Terrabuilder will cost you money, but Terrabuilder lite is free, but it has some limitations. I would go for the payware. :rolleyes:

Terrabuilder guide which is found on the website tells you what to do with the program.

I want to use Terrabuilder for future development. Go for it ;)
 
Rather use the correct FSX method, it is described in detail in the Terrain and Scenery SDK (Terrain and Secenery.html). It is very easy to do, just follow the examples. What I like about this method, is that it will absorb the images into the bgl file. so you don't have to worry about cutting the image to pieces, image format, etc. There will be no images to distribute with your "background"; everything will be in the bgl file.

You will find it just about at the end, just search for Example 3: Creating Custom Terrain Textures

Yes, I would also use the resample tool from the SDK. With all the given examples it should be quite easy to use. Especially if the image you have is already in the GeoTIFF format and WGS84 projection.
 
I followed the instructions for #3 and got the image into fsx, but the border from the image was still there. I used the null 255,255,255. My border was a yellow and not white. I used google earth and global mapper to make the geoTiff.

Any help thanks
 
In my limited work so far, I haven't had good luck with null values on tiffs. I use the blend channel to mask off the border. Actually, I use a gradient to make it more gradual, ensuring full black where I don't want coverage.

Click to expand...

In that case you would have to enter yellow and not white as the null value. Just make sure you enter the RGB values of the color that is on your border. Or use a blend channel to make things transparant.
 
What's the correct method for defining the blend mask in the .inf file? The SDK did a poor job of properly defining how to do that. Obviously, the blend masks are done using alpha channels.
 
Of course the SDK does a bad job, it describes all settings you need in great detail. Example 4 of the SDK for example shows how to use both an water mask and a blend mask in your images.

Also check out the Channel_LandWaterMask and Channel_BlendMask parameters that you can use in your INF file. They can be used to determine which channel of your image is used for water and which for blending. If the order is not as expected by default, you need to set it with those.
 
IMHO it's easiest to either create both the water mask and blend as separate 8-bit grayscale images and use the mulit-source format of the inf while specifying the channel usage of the 2 grayscale images. In this case the main image is 24 bit. The alternative would be to include 1 of the grayscales into the alpha channel of the main image (so it would then be 32 bit). Again, you need to specify in the inf file which channel is which if you don't follow the defaults.
Look at the multisource_multichannel.inf example in the SDK. The SDK example is based on using a separate day and night photo, so they share the same masks.

I have a question. When I drag the text file "MillenniumImage" that has this in it. How does it know the coordinates to put the image at? The other files have them but not this one.

[Source]
Type = GeoTIFF
SourceDir = "SourceData"
SourceFile = "MillenniumImage3.Tif"
Layer = Imagery
Variation = Day
NullValue = 255,255,255

[Destination]
DestDir = "Output"
DestBaseFileName = "Millennium_Image"
DestFileType = BGL
LOD = Auto
 
When the
Type=GeoTIFF
then the locational data are included within the source image, referred to as "tags". These tags are placed in standard Tiff-format files by GIS software. There is a freeware program called gedtiff header examiner which can read out the location tags in a geotiff file. Note that in addition to the location data, the tags also include information about the projection and datum used for the data. For FSX these must be geographic and WGS84 respectively, or resample will give an error about source file not being found. A common problem is that a different datum such as NAD83 is specified. Even though this datum is functionally the same as WGS84, if resample sees this in the tags it won't accept the source file.

Thanks for the link program works great.

Anyone know where I can download imagery that tells me the meters per pixels? I am just guessing on the pictures I am using so it is taking a long time. How can I calculate this? Anyone know how to do it with google earth?
