[gdal-dev] georeferenced but not georeferenced?

[Matt.Wilkie at yukon.ca]

Hi all,

I'm creating images from SPOT6/7 archive DIMAP format. The resulting images display in the correct position in the world when combined with other sources, however all the usual tools say the images have no georeferencing. 

* If the images have no georeferencing how do ArcMap/Pro and Qgis know to put them in the right place?
* How can I convert whatever-this-is into proper georeferencing so that other tools know how to handle them too?

Attached is a sample image.  It was created with (on one line):

    gdal_translate  -outsize 100 0 
    -co compress=zstd -co predictor=yes -co level=17 -co bigtiff=yes -of cog 
    .\path\to\IMG_SPOT6_MS_001_A\DIM_SPOT6_MS_201609082010410_SEN_1.XML 
    source_tiny.tif

The biggest problem this causes me at the moment is that gdal_pansharpen.py output does not have any kind of goereferencing, and I can't use old faithfuls like listgeo, geotiffcp, or gdalcopyproj.py to copy the coordinate system across.

thanks in advance for your thoughts,
