• 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, Arno.
Watching your video tutoial, I had an idea.
You are using GeoTIFFs with embedded coordinates. But many people work with BMPs or PNGs.
I suggest to add to the IMPORTGDAL step a new argument:
Code: 
IMPORTGDAL|filename|lonmin;lonmax;latmin;latmax
So, if I want to detect trees from a simple picture, it could be looks something like this:
Code: 
IMPORTGDAL|image.bmp|44.4560768586739;44.678750534085;37.8990662097931;38.1775921583176
But if I have GeoTIFF with coordinates, it could be looks simpler:
Code: 
IMPORTGDAL|image.tif|*
Another way to do that: add coordinates manually in the Texture Filter Editor and write them into *.tfc file.
 
Hi,

If a lot of people have images that are not geo referenced that might be an option. I was assuming most developers will have their sources geo referenced.

Another option might be to read the coordinates from the resample inf file.

The texture filter editor is not the place for this, since in general you will only run a representative subset through that tool and not all images. That editor doesn't require geo referenced images either. It can work with any format.

Most developers I know, have to use non-georeferenced images. But usually we have coordinates of an image's corners in a kml or map-file.
 
Hi,

I have now added a new step IMPORTINF that can read the resample INF file. It will take the coordinates from the INF file as well. So that should work for non-georeferenced images.
 
Thank you Arno and Vitaly
this is a great addition to ScenProc
i was waiting for this to be supported
